Preheat oven to 350 F. Grease sides and bottoms of each cup of your cupcake baking pan. Blend cake mix, oil, eggs and water in a large bowl (follow the instructions on your specific box of cake mix). Pour batter in cupcake pan and bake for 18-21 minutes. Let the Minnie Mouse birthday cupcakes cool completely before frosting.
MINNIE CUPCAKES FROSTING
While these DIY Minnie Mouse cupcakes are cooling, cut the tip of the bag and the insert the 1M Wilton tip, then add the frosting to fill the bag, leaving enough space at the top in order to twist the bag so frosting will not leak out.
Once cupcakes are completely cooled, frost with the vanilla frosting. Add 2 Oreo cookies on each side of the cupcake to create Minnie ears.
MINNIE PINK BOWS
Knead the fondant until pliable. Lightly brush your bow mold with powder sugar. Take 1 tablespoon of pink fondant and push into your bow mold.
Create 24 pink bow. Place each pink bow between the 2 Oreos. You now have Minnie Mouse cupcakes with Oreos!
