Finn Cakes are tasty and special cupcakes that are shaped like Finn and were created by him. They are only to be eaten by Finn. Finn tells Jake not to eat his Finn Cakes when Finn was leaving to pick up BMO from soccer. The Bear ended up eating all of the Finn cakes and Jake recorded it on video. Finn was still angry at Jake, even though Jake didn't eat the Finn cakes since Jake stood around watching the Bear without stopping him.
Use chocolate cupcake mix or make chocolate cupcakes from scratch. Frost with vanilla frosting, use a small circle of fondant for Finn's face, and draw Finn's facial features on it with chocolate frosting. Use marshmallows for ears.
Finn cakes are cupcakes that have Finn's face frosted on them. They also have a blue patterned wrapper, possibly trying to resemble his shirt color.
