Mix the white cake mix according to the package directions. Divide the batter in half. Put a few drops of green food coloring in one half of the batter and a few red drops in the other half. Mix until the color is spread evenly through the batter.
Pour each batter into an 8 inch cake pan. Bake according to the package directions. Once the cakes are baked remove from pans and cool on a wire rack.
Once the cakes are cooled place the green cake on a cake round. Spread with 1/2 cup of frosting. Top with the red cake.
Use all but 1/4 cup of the remaining frosting to frost the tops and sides of the cake.
Alternate the gingerbread men, trees, and snowmen around the outside edge of the cake.
On top of the cake place a PEEPS® snowman at the edge of the cake facing inward. Place two PEEPS® Minions facing the snowman as if they are building him.
On the opposite side of the cake place one PEEPS® Minion laying flat and face up on the cake with a gingerbread man next to him.
Finally, place 1 Milk Chocolate Dipped Sugar Cookie Flavored Chick on the edge of the cake. Using a bit of the remaining frosting stick a PEEPS® Minion on the back of it so it looks like he is riding the Chick.
Use the remaining frosting to stick mini marshmallows to the Minions sides and all over the cake as snowballs.
Pipe the red icing on a few of the Minions heads to make Santa hats, using a mini marshmallow as the puff ball on the hat.
Finish the cake by piping the red and green icing around the edge of the cake in a decorative way.
