April Fools' Day Cheeseburger Cake - cooking recipe

Ingredients

1 (18 ounce) box white cake mix
3 egg whites (or as called for by your cake mix)
1/3 cup oil (or as called for by your cake mix)
1 1/3 cups water (or as called for by your cake mix)
1 (18 ounce) box brownie mix
1/4 cup water (or as called for by your brownie mix)
1/2 cup oil (or as called for by your brownie mix)
2 eggs (or as called for by your brownie mix)
5 sugar cookies (4 inches wide)
1 (16 ounce) can vanilla frosting
red food coloring
yellow food coloring
10 spearmint candy leaves
1/4 cup granulated sugar
1 (16 ounce) can milk chocolate frosting

Preparation

Heat oven to 350\u00b0F
Grease 2 8-inch layer cake pan.
Prepare the box of white cake mix and bake according to the recipe.
Cool on wire racks.
Invert cakes on rack after 15 minutes and let cool completely.
Prepare the box of brownie mix, and bake as directed in the 8 inch layer cake pan.
Cool for 15 minutes in pan, then invert and let cool completely.
\"Tomato Slices\" Place plain cookies on a wire rack set over wax paper.
Put about 1/2 cup vanilla frosting in a small saucepan.
Stir over low heat until melted and smooth.
Remove from heat and stir in red food coloring (and a bit of yellow if needed) until frosting is tomato colored.
Brush or spoon on top and sides of cookies.
Let stand at least 30 minutes until firm to the touch.
\"Cheese\" Spoon another 1/2 cup of vanilla frosting into a small bowl.
Stir in yellow food coloring (and a drop of red if needed) until cheese colored.
Cover to prevent drying.
\"Lettuce\" Sprinkle granulated sugar on a large sheet of wax paper.
Working with 1 at a time, place spearmint leaves on the sugar and fold wax paper over, so the candy is sandwiched between the sugar and the wax paper.
Roll with a rolling pin until flattened and edges are jagged.
The candy will become very sticky, but the sugar should help it release from the wax paper.
\"Buns\" Put remaining vanilla frosting in a medium sized bowl.
Stir in milk chocolate frosting and red and yellow food coloring, little by little, until frosting is the color of a hamburger bun.
Place one cake layer on a serving plate.
If well-rounded, best to cut off the hump, then put it upside down for the flat top.
Cover with frosting.
Arrange spearmint leaf \"lettuce\" on top and around edges of the bottom \"hamburger bun\".
Place brownie cake on top of the \"lettuce\" using spatulas.
Spoon \"cheese\" about 1 inch from edge of top of burger, letting some run down the sides.
Top with \"tomato\" slices.
If needed, now is the time to insert toothpicks through the brownie layer (leaving at least 1/4\" above the tomato cookies) to keep the cake layers from sliding off!
Take the cake layer that rose the most for the top \"bun\".
Place cake on wax paper and frost with remaining bun colored frosting.
Lift onto tomato topped burger.
