Somehow I found myself in the position of the one person who brings the unusual and fun dessert the kids all love. In keeping up with this tradition, this past Labor Day I made Lego cakes. Using the basic recipe idea from Betty Crocker. I modified it a little because I find the Wilton dyes to be a bit more stable in frosting.
- 2 box of cake mix – the flavor is your choice but we used white vanilla
- 2 cans of white frosting
- 1 bag of standard sized marshmallows
- 3 – 1oz Wilton icing dye bottles – Golden Yellow, Red-Red, and Royal Blue
- Bake the cakes according to the packaging in 13×9-inch pans. Be sure to grease the pans well because you want it to be easy to remove without any cracks on the bottom.
- While the cakes are baking, cut at least 20 marshmallows in half. You want to make sure you have enough so going a little high is okay.
- When the cake are finished baking, wait 20 minutes and then carefully remove the cakes from the pans and onto a flat surface. I used cookie sheets for this.
- Freeze both the marshmallow halves and the cakes for at least two hours.
- Take two bowls and put half of each frosting can in each. This leaves you with 4 portions of frosting. Put 1 portion to the side. In the other 3, add dye to each to reach the desired Lego colors(red, blue, yellow).
- Cut the tops of the cakes where it domed off using a serrated knife to give you a flat surface. Cut the cakes each into rectangular portions. (As you can see some of my cake had an accident so one of my rectangles is smaller than the others.)
- ***I made a special display for my cakes using printed images of the Lego green baseplate on top of cookie sheets and covered them with cling wrap. You can display yours how you wish but it made the Legos look more Lego-like to be on their own base.
- Place the 4 pieces of cake neatly upside down on the display you are using. Lightly frost the outside of each cake the color they are going to be and then put the cakes back in the freezer for an hour. Then finish frosting each cake.
- Now the fun and messy part, take you marshmallow halves from the freezer. Carefully frost the halves to match each cake and place into location to look like a real Lego building block. When you are finished the cakes should look like several Legos. This step can be really messy so be careful.
Now, sit back and watch the smiles because every kid loves to eat a piece of Lego cake!
