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

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

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.

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


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!

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!!

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.

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!
