1UP Cakes




About: I live in the UK. Half my time is spent running events for people who make videogames, the rest is spent prototyping… things ¬¬ I used to take my toys apart and put them back together when I was a kid. One ...

Make cakes that look like 1UPs from Super Mario Bros.


These ones look like they were made by a five year old. I am 27, and have no excuse. YMMV.

Step 1: Collect!

You will need:

Cake bases:

Baking powder (if your flour isn't self raising).

(This is actually adapted from a muffin recipe, but for some reason comes out tasting like scones. Savoury works quite well with the amount of chocolate you're going to be putting on these)

White chocolate (2 - 3 decent sized bars should be enough)
Green food colouring
Cooking oil (Can substitute milk - this is to loosen the chocolate and stop it binding if it dries out during melting).
White chocolate buttons.

Various mixing bowls, whisks, spoons, pans etc. as required.
A small muffin tin. I recommend the silicone type shown in this instructable, as it gives the closest to a mushroom shape I've found and they also pop out of it very easiy without any greasing.

Step 2: Melt! Mix!

First, melt the butter on a pan on the hob. Keep it moving so as not to burn it, and take it off the heat for a little while if you need to.

Now break a medium egg into your mixing bowl, and whisk it up. Add half a cup of melted butter, then a cup of milk, then whisk them all up. Photos above show this in far too much detail.

Step 3: Mix!

Now, in your other mixing bowl, mix up:

2 and 1/2 cups of flour
2 tablespoons of sugar
and 1/2 a teaspoon of salt.

If your flour isn't self raising, add 2 teaspoons of baking powder too.

Now dump in the wet stuff you mixed in the last step too, and mix it all together until it forms delicious, sticky muffin dough.

Step 4: Bake!

Now use a couple of teaspoons to portion your dough out into the tray. To avoid air bubbles in the bottom, I find it best to push a bit of dough right down into each muffin compartment first, then build up more on top. To get a good mushroom top, I also put a bit more in than they can hold rather than leaving them level.

If you're using a silicone tray like the one in the pictures, you don't need to grease it or anything, they'll pop right out when they're done. If you're using a metal tin, you'll need to grease it and might want to use paper muffin cases too.

Bake them at gas mark 5 (190°C, 375°F) for 25 minutes, and they should look like the ones in the third pic below.

Step 5: Melt!

Now to make the icing.

Break up all your chocolate into a microwavable bowl, then blast it for a while on a defrost setting or the lowest power you have available. Keep doing it until it gets a bit melty like in photo #1, then you can stir it up.

Now add your food colouring, and be ready for something ugly to happen: Chocolate is oily, and most food colouring is water based. So, the same as if you're melting it in a steamer and some water gets into it, when you add colouring the chocolate will immediately seem to dry out and stiffen, going powdery and lumpy in places.

You can sort this out by adding a little bit of cooking oil or milk - not too much or it will get really watery and not be able to set.

Keep adding colouring and oil/milk as needed until you get the shade of green you want, and that's your icing ready.

Step 6: Dip!

After letting the cake cool for a while, dip them in the icing to give them green tops. You might need to microwave your icing for a little while if it sets too much during this step.

Next add the white chocolate buttons to create the white spots, but make sure to let the icing set for a while before doing this. If you add the buttons too early, they'll go blobby and melt off the sides, but if you add them too late, they won't stick.

Step 7: Refrigerate!

Now pop them all in the fridge to set, lick your kitchen stuff clean, and within a few hours they'll be ready.

I take no responsibility if you do super dangerous stuff after eating these.

    Look down to eviloverlord's comment. A few decades back they marketed powdered baby formula with sales reps dressed as nurses, who told mothers it was better than breast milk. They did this in countries where the water isn't potable, so a lot of babies caught diseases and died.

    you should at least try to be nice. the person who made this put a lot of work into it and for you to scold them on chocolate is just ... wow. next time if you want to state your opinion like THAT then do it on your blog. not cool.

    Personally I don't think boycotting solves much at all (it just turns a tiny segment of the market invisible and the companies keep rolling on), but it's worth knowing these things about companies.

    instead of buttons could you just put a few dollops of white chocolate ( maybe some Parafin wax mixed in) and put them in the freezer for a bit? think i'll try it :)

    I have make my own fondat out of marshmellows and powdered sugar and if you chill the mushrooms unil they set and use fondat for the white circles and put a dab of icing to hold it on it will most likely do better

    I made these a few months ago and they were fantastic! The cupcakes aren't fantastic without the icing though.

    Whatever you do though, do not use a steamer to melt the chocolate! I stupidly done this with my first batch of chocolate (I planned to make red and green mushrooms) as my sister told me that it would work, it ruined my red chocolate. Definately mix in the oil before adding food colouring too, it works wonders if you keep stirring.

    I'm making them again tomorrow but with a usual fairy cake recipe :)

    You should totally do up a bunch of red ones, with an HGH supplement in them. I was thinking though, instead of the Icing/white chocolate setup it might work better if you first put a "head" of cream-cheese icing on the shrooms, (leave it white) and wrap it with a sheet of red/green fondant with holes cut in it to let the cream cheese come through, (maybe I'll do an instructable to that effect. )


    Reply 9 years ago on Step 7

    the fondant with cream cheese sounds like it would be a good effect, but my only worry with that would be if it got warm, your cream cheese would probably get all over the place :)


    Reply 9 years ago on Step 7

     yeah, but most cream cheese icing is thicker than straight cream cheese, and you would probably wanna aerate it to make it puffy

    but, What no comment about the HGH shrooms?
    I thought that was funny. . .

    just an idea here, perhaps after you have beate the egg into the batter add two drops of vanilla for flavoring? This would give it that kind of cake like effect. :)


    Reply 9 years ago on Step 6

    White Cake Icing doesn't give you that sheen that a chocolate (for lack of a better word) ganash can. The chocolate also adds a bit of flavor, because the recipe in and of itself for the cake (or quick bread for those that are semantics about it). I'm going to post earlier, that maybe a drop or two of pure vanilla may be helpful in the batter, but I would NOT put it in the chocolate...
