We have been Minecraft fans for a long time, so it’s pretty amazing this was my first time throwing a Minecraft Birthday Party. I’m going to do an entire post outlining the party and what we did, but the Minecraft cake we made deserves its own post. Saying it was a Minecraft cake is a little misleading, technically it is a Minecraft rice crispy treat. That’s right, I took my favorite treat and made a giant Minecraft TNT rice crispy cake! It isn’t TNT without a fuse, so we added a cake sparkler! Like all things in Minecraft, the TNT block is a cube. It measures, 9 x 9 x 9″.
This cake was so much fun to put together. It was a little time consuming, but compared to a traditional cake with icing and fondant, this was a breeze! I will tell you that I used about six 12 oz boxes of rice cereal, which was about 48 cups worth! Thanks to a big pot, I only had to do one huge batch per layer. I will break down exactly what I did below, but first check out the how-to video. It gives you a good idea of how I put the TNT block together and what it looks like with a champagne sparkler on top!
CAUTION: A sparkler can be dangerous. Only allow adults to light the cake sparkler and make sure to take appropriate fire safety precautions. We always had a bucket of water or a fire extinguisher at the ready in case of trouble. Follow safety precautions and use common sense when lighting a sparkler. This is an outdoor activity!
- 48 cups crisp rice cereal (about 6 12 oz boxes)
- 3 sticks + 2 Tbsp margarine
- 8 10oz bags mini marshmallows
- Super Red Gel food color
- Super Black Gel food color
- White Gel food color(optional)
- 6 qt stock pot
- 3" T, N Cookie Cutters
- Fat Daddio 9 x 9 x 3" pan
- Cake Sparkler or Champagne Sparkler (They are the same thing, but depending on where you are looking, they are called different names)
- Heat 1 stick margarine over low heat in a 6 qt stock pot. When the margarine has completely melted, add 25 ounces (2.5 bags)marshmallows. Heat the marshmallows until completely melted, stirring occasionally. Remove from heat.
- Add red gel coloring until the melted marshmallows are a deep red color. Stir in 15 cups of rice cereal until it is completely covered in marshmallows. Pour the treats into a greased 9x9x3" pan. Press the treats down into an even layer with greased hands or spatula. Allow to cool.
- Repeat these steps and make a second red layer and a white layer.
- Heat 2 Tbsp margarine over low heat until melted. Add 5 ounces(1/2 bag) of mini marshmallows and stir to coat. Heat the marshmallows until completely melted, stirring occasionally. Remove from heat.
- Add black gel coloring until the melted marshmallows are black in color. Stir in 3 cups of rice cereal until it is completely covered in marshmallows. Pour the treats into a greased 9x9x2" pan. Press the treats down into an even layer with greased hands or spatula. Allow to cool.
- Center one red layer of treats on a cake board.
- Cut the front 1 - 1.5" of treats off the white layer and set aside. Cut T-N-T from the black treats with the letter cookie cutters. You will need to trim the letters to match the height of the white layer.
- Stack the white layer on top of bottom red layer. Press the TNT letters into place. Use the cut white strip from above to fill in around the layers. Heat the white treats in the microwave for 5 seconds to make them more pliable if necessary.
- Cut a hole in the top red layer to fit the cake sparkler in. Stack the red layer on top. When it is time to light the cake sparkler, insert it into the hole and light.
The champagne sparklers we used burned between 40 seconds and a minute each time. We bought 8 sparklers and we’ve pretty much used them up because it is so fun! The adults may have found it more entertaining than the kids.
Full disclosure, we ended up not eating the cake. I will tell you why. My first sparkler tests were done with a white surface underneath and after two tests I noticed a fine black powder on the board. I figured if it was on the board it was probably on the cake. The other reason is that I made this ahead of time and didn’t put effort into keeping it covered so the rice crispies were stale by party time. If I was going to serve this, I would keep it covered to keep it fresh. I would also remove the top layer and serve the bottom two layers only. That would personally make me feel comfortable that I was avoiding any soot or whatever from the sparkler. However, we didn’t eat it so I’m not making any claims about it’s safety.
We had to buy the champagne sparklers online and they can only be shipped via ground. Keep this in mind when you are planning out your cake. As a back-up plan we purchased some number sparklers too. I was able to find some at a party supply store as well as online. My son turned 10, so of course we got a 1 and 0.
We had a really hard time getting these to light. We held a lighter on each one for the best chance to get them to light simultaneously and it still didn’t work. They also dropped some burned up debris on the cake. Here’s what it looked like lit up! It was still fun, but I prefer the cake sparkler.
We also tested out those birthday candles that spark. They are long skinny candles and look much more like typical birthday candles. We didn’t take any photos but it is extremely underwhelming. They mostly just let out a random spark here and there. Honestly, I can’t recommend them, at least not for this cake.
That was a lot of words for a relatively simple process. Three big batches of rice crispy treats and a half batch of black is all it takes to put together a Minecraft birthday cake. It really was the star of our Minecraft Party. I can’t wait to share the rest of the party with you this week!
