Bake the Cake Prepare the cake mix according to the package directions. Bake in round cake pans or a sheet pan and let the cake cool completely before frosting. Cut out circular shapes to fit into a small dish.

 Frost the Cake: Spread a thick layer of vanilla frosting over the top and sides of the cake. The frosting needs to be thick enough for the sprinkles to stick properly.

Add the Dots: Pour rainbow nonpareils into a large bowl or tray.

Carefully press the frosted cake into the sprinkles or gently press the sprinkles onto the cake using your hands until fully coated.

This is what gives the cake its viral “dot” appearance.

Chill and Serve: Place the cake in the fridge for about 20 to 30 minutes to help the frosting set.
