What would I change? 1. I would use paper cupcake liners (as originally planned) in order for the cotton ball tails to stick better. 2. I would replace the butter in the frosting with shortening to get pure white instead of off-white. 3. I would have (as my mom suggested) baked the cookie ears with a toothpick or stick in them to help them stay on the cupcakes a little better.
Hope you all had a Happy Easter!
