Here is what you need for this R2D2 Cake:
1 9×13 cake homemade, freeze about 45 minutes first
3 cups butter cream frosting
M&Ms and Twizzlers for embellishments.
I got a basic outline of R2D2 off the internet, search for “coloring pages”, or “how to draw R2D2”. Then I blew it up to 8 ½ x 11. I then drew it onto a piece of wax paper with permanent marker. R2D2 has a lot of detail, its better to simplify and just do a few on the cake.
1) Trace shape onto cake using waxpaper and toothpicks
2) Cut the cake into the shape of R2D2
3) Freeze cake 20-45 minutes to make it easier to frost edges
4) Color frosting (can be done the night before)
5) 2 cups white
6) 1/2 cup gray frosting (1 red: 1 green: 1 blue)
7) 1/2 cup blue frosting
8) Do the white frosting first and the gray dome.
9) Let sit 15 minutes until the frosting is hardened a bit and then laying a smooth tissue over the frosting and rubbing a spatula in careful circles over the tissue, smooth the frosting to give it the smooth fondant look.
10) Use a toothpick to sketch on blue and silver designs
11) Sketch blue designs
12) Pipe on blue with largest tip available
13) Pipe on gray designs with a narrower tip and outline R2D2’s white areas.
14) Embellish with red and yellow peanut butter M&M’s and Twizzlers for the wires on R2’s feet.
2 cups all-purpose flour
2/3 cups cocoa powder
1 ¾ tsp baking soda
½ teaspoon baking powder

Loosen cake edge from pan, invert on a rack, remove waxed paper and cool completely.
6 cups powdered sugar, divided
¾ cup butter or margarine softened
¼ cup shortening (makes better frosting for decorating)
6-8 tablespoons milk, divided

Combine 3 cups powdered sugar, butter, shortening, 4 tablespoons milk and vanilla in a large bowl. Beat with electric mixer until smooth. Add remaining powdered sugar; beat until light and fluffy, adding more milk, 1 tablespoon at a time as needed for good spreading consistency.
