Introduction: Rice Krispie Treat Watermelon

Picture of Rice Krispie Treat Watermelon

We were invited to a couple of 4th of July parties this year and needed a treat to bring. So I came up with the Rice Krispie Treat Watermelon. My kids love faux-foods, and this one we came up with on our own.

Strawberry flavored marshmallow Rice Krispie treats with dried blueberry "seeds" covered with fondant.

Step 1: Ingredients

Picture of Ingredients

I used the standard Rice Krispie Ceral Treat recipe. I had to double it to make mini watermelon. So buy 1 large box of cereal and 2 bags of strawberry marshmallows.

You still need to make in two separate batches to make it easier to handle.

Watermelon Filling
3 Tablespoons of butter
6 Cups of Rice Krispie Treat Cereal
1 10 oz. bag of Kraft Jet-Puffed Strawberry Marshmallows
1/4 Cup of dried blueberries

Watermelon Skin
8 oz of mini marshmallows (half a bag)
1 pound of powdered sugar

shortening (for your hands)

Step 2: Watermelon Skin

The skin of the watermelon is made from fondant. Do not use pre-made fondant from a bucket. Make you own. The recipe I used is from Peggy Weaver's site.

Just follow the directions on her site. It is the best tasting fondant and is easy to make. Once you have the base fondant made start adding color. I started with equal parts green and yellow. Add just a few drops at a time and work it in. Once you have a good yellowish-green put a third of it in a plastic bag. Now start darkening the remain 2/3 with more green and some blue. Again work in the colors a few drops at a time before adding more. If your green is too bright add a drop of red. Compare to you light green to judge your colors. Put the darker green in a baggie and place them in the refrigerator.

Step 3: Watermelon Insides

Clean up from the previous step. I made my treats using the microwave. I first melted three tablespoons of butter. Then add one bag of StrawberryMallows and coat with butter. I heated them in 30 second increments. Stir in between each heating. After a minute most of them should be melted, if not continue to mix. There should be enough heat to melt the rest.

I added about 5 drops of red food coloring, I wanted the inside to be a little more pink. Now add 6 cups of Rice Krispie Cereal. Stir them in with the dried blueberries. (Our first thought was to use chocolate chips, but they would have melted too easily.)

Spread the mixture on to a greased cookie sheet to let it cool. Now repeat the recipe again and add the second batch on top of the first.

When it has cooled enough to handle, roll it up into a log and cover with waxed paper. It needs to cool for an hour or longer. If it is too warm it will loose it's shape.

Step 4: Forming the Melon

Picture of Forming the Melon

Use your hands and starting shaping in to melon. My wife thought it looked like raw hamburger and my daughter thought it looked like a brain. If it holds it shape then your are ready for the fondant. If it starts to sag, let it dry out some more.

Get the fondant it out and knead it some. It will warm up quickly. Use powdered sugar to keep it from sticking to the counter and rolling pin.

I used a piece of plastic wrap to get the size I need to roll out. Make sure your stripes are in the right direction.

Step 5: Finshing Touches

Wrap the Rice Krispie shape up in the fondant and work out and seams. You can add more stripes over the green and just smooth them in. If it is getting sticky add a little powdered sugar and rub it in.

If you have it outside slice it quick, the humidity make the "skin" stick together. It may not be as refreshing as a good watermelon, but you can make them year round.

hi just wondering how do you store this recipe if I was to make it for a party? and also, how long would this recipe keep for? thanks :)

bwente (author)bchang62015-06-28

About 3 to 4 days, wrapped in plastic wrap at room temperature.

susanchen2011 (author)2012-07-11

Wow this looks beautiful and delicious!!!

swolfphoto made it! (author)2012-07-06

This was such a great idea! And I found it in perfect time to make for the 4th of July! I was so worried about the fondant being too think since I have never used it before but it turned out perfect. It was such a big hit at my party, everyone loved the way it looked and it tasted so good too! I couldn't find dried blueberries so I used dried cranberries and they were so yummy! Making it was a lot of work but definitely worth it. Thanks for the idea!

bwente (author)swolfphoto2012-07-07

I am so happy you made a watermelon. I totally forgot about this year. We were on vacation and did not have a picnic.

The fondant recipe is so simple and it is a perfect complement to the marshmallow treats. It looks like you had no problems, you photos are great. Cranberries are far easier to find and a whole lot cheaper too. I was trying to keep the cost down with the blueberries ($8 for 8oz). I think I will need to increase the amount to a more appropriate watermelon to seed ratio by using cranberries.

Great job!!!

jmiksanek (author)2012-03-22

Wow! This is brilliant. I can't wait to find a good occasion for making this:)

Peterdaughter (author)2011-07-07

Very creative and fun. Great instructions too!

xfangsxupx3 made it! (author)2011-07-04

I made this for the fourth of July and it was a huge hit at my party! Thanks for the instructions! It was really easy and fun to make. I used raisins as my seeds.

TheGarrison89 made it! (author)2011-06-27

Very cool! My girlfriend and I decided to give this a go and it turned out great!

We could not find strawberry marshmallows locally so to substitute we just added a fair amount of red food coloring(12 drops in total for our 10 ounces of marshmallows).

Also, dried blueberries were going to be very expensive, in relative terms($6 for a small bag!!) so I decided to get a cheap $1 box of cupcake mix with imitation blueberries instead. I just sifted out the blueberries and used half(~25) of them in the watermelon. It tasted and looked great, saving me about $5(also got a box of blueberry muffins ready to be baked). We ended up making this one for under $6(already had the powder sugar and food coloring, bought everything else).

And to anyone about to attempt this, I can't stress enough how much lots of crisco helped. Next time I do this(Yes there WILL be a next time ;D), I'll make sure to have the fondant a bit thinner on the watermelon, as ours was very sugary. Pictures are attached, thanks for an amazing recipe!!

bwente (author)TheGarrison892011-06-27

Fantastic job! Very resourceful.

Raisins would cheaper than blueberries, but not they way you did it. I used two bags of dried berries for three watermelons and started to run out by the last one. (I wish I had taken a photo of the first one cut up)

I got the strawberry marshmallows on sale. I think they were trying to get rid of them, not a lot of demand I guess.

fofmock (author)2010-12-15

maybe just a small bit of cocoa krispies for the seeds would work...

barkingmonkey (author)2010-07-09

I wonder if you could freeze the chocolate chips for a few days to harden them up against the heat. I think an experiment is needed! But this looks like something the grandkids would love!

Or freeze brown m&ms

Granny_Leah (author)2010-07-30

I found your instructable on today's edition of my food looks funny .

TheGeek1984 (author)2010-07-07

That's Awesome! I recently found out (the hard way) that I'm allergic to melons, and I love watermelon... :( But now I can have it again! :) Very creative! Like...10 thumbs up!

bwente (author)TheGeek19842010-07-07

If you have a chance to try it making one with watermelon drink mix before me, let me know how it turns out.

TheGeek1984 (author)bwente2010-07-07

I'll do that! I'm going to make my first attempt for my cousin's 19th birthday party this weekend actually.

TheGeek1984 made it! (author)TheGeek19842010-07-11

I made it! I couldn't find a drink mix that was just watermelon, so I used watermelon/cherry. I had some trouble with the fondant sticking a lot, and my decorating could use some work, but overall it turned out great! Awesome recipe and wonderful idea! :D

bwente (author)TheGeek19842010-07-11

Awesome! The next one I make I will definitely use watermelon flavoring. I had bought out the stores supply of strawberry marshmallows anyway. I think I will also add some vanilla extract to the fondant. Especially if the kool-aid is a little tart.

TheGeek1984 (author)bwente2010-07-11

The fondant on it's own seemed to counter the tartness, I hadn't even thought of putting vanilla in it though. The flavor of it is basically like if you only added half of the sugar needed for a gallon of kool-aid, so it wasn't bad or anything.

monkeymojo made it! (author)2010-07-08

Very nice, I tried it out tonight. My first one is more of a watermelon-loaf of bread hybrid shape.. When you used powdered sugar to keep the fondant from sticking when rolling it out did you have trouble with it leaving white spots on the fondant? I ran into this and I was able to brush it off the light green; however, the dark green stayed spotty in some places. I got it off some with a light brushing of water but this lightened the fondant slightly..

bwente (author)monkeymojo2010-07-08

Great job! I am impressed., that you were able to make it from instructions. Was this your first time with fondant? I was able to use my hands and work the powdered sugar into the fondant. In fact I added more once I covered it to take some of the shine off.

You got a good dispersion of "seeds". By my third watermelon I was running out. Which happened to be the one I took pictures of.

Did you use strawberry marshmallows or did you use regular and add food coloring?

Also, what do think of the taste? Everyone here really likes the taste of fondant and rice krispie treats.

monkeymojo (author)bwente2010-07-09

This was my first time with fondant, it was messy but fun! I worked the powdered sugar in but ran into trouble while rolling the fondant out. It was sticking to the counter so I sprinkled some sugar down to keep it from sticking.. It stopped the sticking but stained the dark green. I looked around and saw that a lot of people recommend either corn starch or shortening. I've got one to make tomorrow so I guess I need to pick one.. I went with the strawberry mallows, I was worried about seeing watermellon but tasting strawberry; however, I think the taste came out quite good. I was going to try to make it with regular mallows and kool-aid for flavoring but figured I would try that for another day because I was worried about trying to get the right dilution of koolaid, especially since you need to cut it with water and I knew that wouldn't get along with the mallows. To make things worse the only koolaid I could find was watermellon-cherry.. Apparently plain old watermellon koolaid is out of style. I brought it into work this morning and sliced it up, so far the reactions are "wow" and "delicious"! Of course, I can barely look at it as I'm the kind of person who is constantly taste testing while I'm making something.. I cut it up this morning and felt my teeth starting to hurt, hah!

TheGeek1984 (author)monkeymojo2010-07-11

In the area where I live I was unable to find strawberry marshmallows, so I ended up using watermelon-cherry kool-aid. Mixing it in wasn't hard as the marshmallows added enough liquid, and the taste is really good, a little tart, but you can taste the watermelon.

ainterr (author)2010-07-10

My family is having a surprise birthday party for my sister (sweet 16). I am going out to get the ingredients now! I just know shell love it haha

mslaynie (author)2010-07-08

This is absolutely adorable, and so creative! Good job! I wonder what else you could use for the seeds, I don't really like dried blueberries...

What about Zante Currants? Suzanne in Orting, WA

Ooh, I haven't seen those before. Interesting idea, though, thank you!

They should be n the grocery store with the raisins. "The Zante currant (Vitis vinifera) is a variety of small, sweet, seedless black grape named after Corinth (currant) and the Ionian island of Zakynthos (Zante) and not to be confused with the blackcurrant, redcurrant, and white currant which are berries of shrubs in the Ribes genus and are in a different family altogether. Like grapes, currants are perennial.The name apparently comes from the Anglo-French phrase "raisins de Corinthe" (Raisins of Corinth)[1]; "Zante" is a recent prefix given to distinguish them from the Ribes berry currants. Unlike blackcurrants, the Zante currant is not a significant source of vitamin C[2]. Zante currants are very small and intensely flavoured. They can be eaten raw, especially when ripe, when they are sweet to the taste. They may also be referred to as table grapes for this purpose. More commonly they are used for making raisins and occasionally wine. When dried, they are often referred to as dried currants or just "currants" and in this form are used in cooking, especially baking and are a major ingredient in currant slice (or currant square) and currant cake. In the United Kingdom they are usually referred to simply as "currants" and often used in scones, currant buns, Christmas cake, Christmas pudding and mincemeat. They are sometimes sold mixed with raisins and sultanas as "mixed dried fruit"." File:Zante currants.jpg

Weird, I've never seen them before! I'll look next time I'm in the grocery store. They sound interesting! Thanks for the information!!

bwente (author)mslaynie2010-07-08

My first thought was chocolate chips. But those would melt and be a mess. You could try black licorice (strips, bite, or drops) or raisins. I didn't use either of those, since my kids don't like them.

mslaynie (author)bwente2010-07-08

Yea, that makes total sense. If your kids won't like it, why bother? Especially with something this cute and fun! Chocolate chips would turn into brown smears, i think. But raisins would work well, I think! This is such a great idea, I told my husband all about it, and how cute I thought it was!

porcupinemamma (author)2010-07-08

very cool! Way to go!

ax89 (author)2010-07-08

very creative! and nice instructable too. well done.

heather1 (author)2010-07-08

love it!

sadiecoons (author)2010-07-08

Thats sooo cute!

gardenwife (author)2010-07-08

What a terrific instructable with good photos and descriptions. This is really fun and creative. I can think of lots of fun ways to adapt Rice Krispie goodness now, too. :)

rkcndy (author)2010-07-08

I can't wait to try this!!!

pperea (author)2010-07-08

Awesome instructable! Thanks

SeamusDubh (author)2010-07-07

Another idea instead of the strawberry marshmallows look for melon extract or watermelon flavoring.

scoochmaroo (author)2010-07-05

LOVE. Love, love love! 5 stars. Keep em coming!

bwente (author)scoochmaroo2010-07-07

Thank you so much. I have fun trying out the stuff I find here. I only post when I have something really special to share. So far I have two.

Spear_man (author)2010-07-07

never commented on an instructable before but WOW!!! very cool.

RavingMadStudios (author)2010-07-06

This is super cool. When I saw the first picture, I thought you had made the skin out of yellow & green Starburst candies. Which might also be tasty, come to think of it....

kcls (author)2010-07-06

That's pretty awesome! Faux foods ARE awesome!

bwente (author)2010-07-06

After talking to friends, I realize some confusion about the flavor. It is strawberry, not watermelon. But that gives me an idea for next time. Since pink marshmallows are hard to find anyway, I am going to get white ones and get watermelon flavored drink mix. I bet it would mix well with the melted marshmallows.

bigmama1079 (author)2010-07-06

Wow, this has to be the most creative food 'ible I've seen in a long time. Keep this up and you just might give scooch a run for her money!

MechanicalMashup (author)2010-07-06

Love it! Gonna make this for our family camping trip. I also love the recipe for the fondant, I like making cakes but the store bought fondant tastes crappy.

muyo19 (author)2010-07-06

Great! I should try this someday.

BeanGolem (author)2010-07-06

Holy damn that's amazing! Genius.
