Just in time for Memorial Day–the hamburger cake! We had a blast putting this together as a family and the grandparents even joined in to add the finishing touch…the olive on top.
Here’s how to put the cake together.
First, the bun:
Mix up a boxed yellow cake mix and divide into two 8″-round cake pans. Bake until golden. One cake will be the top of the bun and the other the bottom. Let your kids choose which cake looks the most like a bun top. Put them in the fridge (the cake, not the kids).
Now for the meat:
Bake a brownie mix in a 9″-round cake pan (or you can use the same 8″, I just like having the “meat” hang over the side). Yup, in the fridge it goes. Note: You will have extra brownie batter if you use a family-sized brownie mix.
You can’t have a decent burger without the fixins’ mayo, lettuce, tomato, and cheese. I bought 1 can of ready-to-go vanilla frosting. Divide the frosting evenly into four bowls.
Spread the red-tinted frosting onto a piece of waxed paper making two, large circles for the “tomatoes.” Put the tomatoes into the fridge. For the lettuce smear the green-tinted frosting onto a piece of waxed paper with a spoon trying to make the texture uneven, like lettuce. Finally, the yellow-tinted frosting is smoothed onto a piece of waxed paper (you’ll cut it later so the edges don’t need to be even). Into the fridge for all the fixins’.
I recommend having a burger assembly team–there is flipping involved, folks! Make a circle just smaller than the bun bottom with a piece of cardboard. Put your bottom bun piece onto the cardboard circle (this will make assembly, cutting, and moving the cake much easier.)
Break up the green-tinted frosting lettuce into large pieces and lay half of them around the bottom of the bun. Spread a little bit of the leftover white frosting (remember that fourth bowl we haven’t used yet?) and carefully place the brownie “meat” onto the bun bottom–this will hold the “lettuce” in place.
Add more lettuce around the edges of the brownie “meat” and then carefully add more white frosting onto the center of the brownie. Lay the two tomato slices on top of the lettuce. For the cheese, use a kitchen knife to slice the yellow pieces into squares that look like American cheese. Place two pieces of your “American cheese” on top of the tomatoes. Use the rest of the white frosting to smear over the bottom side of the bun top for the “mayo.” It’s flipping time! Flip the bun top onto the cheese layer–carefully (this is a two- or three-person job). Gently push down on the bun top.
With the remnants of white frosting, stick crispy rice cereal pieces onto the top of the bun to look like sesame seeds. We had leftover red and green pieces from constructing the lettuce and tomato so we made it into a green olive for the top of the burger.
Voila! It’s hamburger for dessert.
