Mix everything in a bowl until you get a thin batter.
I then poured the batter into mini muffin tins with cupcake liners.
Bake them at 350°F until a toothpick inserted in the center comes out clean. I started checking my cupcakes after about 6 minutes.
I then topped the mini cupcakes with the chocolate buttercream frosting. I added cocoa powder to the frosting by the tablespoon until I reached the desired flavor.
I also added brown Wilton Gel Dye until I reached the desired color. After the frosting was piped on, I topped with chocolate sprinkles!
