Make homemade vanilla cupcakes with vanilla frosting and add tint with blue food coloring gel or use cake mix and canned vanilla frosting to get the number of cupcakes you need. You’ll need enough blue frosting to lightly frost the cupcakes, plus additional blue and vanilla frosting for the decorations. See How to Make Schnauzer Cupcakes for step-by-step instructions and photos.
For the basic frosting on top of each cupcake, you’ll only need enough to lightly coat the top of each cupcake, about ¼ cup frosting per cupcake. Too much frosting on the cupcake will make it harder to decorate into the puppy face.
