Divide cake batter into 4 portions. Color 2 portions with yellow and 1 portion with sky blue. Divide remaining portion into 4 equal portions. Color portions black, gray and brown. Leave one portion uncolored. Spoon each colored portion into a piping bag. When ready to pipe, cut the tip of the piping bag with scissors.

Minion Ice Cream Sandwiches Assembly
Soften ice cream and shape an ice cream block in a small freezer safe dish. I used a small baking sheet. Freeze for at least 2 hours. Cut it up into sections. Peel the cakes from the wax paper, chocolate should be firm now. Sandwich ice cream filling between 2 minion cakes. Ice cream will not stick to the cakes right away, let it soften for a couple minutes and then press the cakes into the ice cream. Store in one layer in a plastic container, in the freezer. Ice cream sandwiches can be prepared ahead of time and frozen for a month.
