Preheat oven to 350°F.

To make the frosting, combine Cool Whip with pudding mix in a bowl, and mix until smooth. Cover and refrigerate until cupcakes are ready to be frosted.

In a large bowl, combine cake mix with baking powder and stir until free of lumps. Add soda and vanilla extract, and stir or whisk until batter is smooth. Set aside.

In a separate bowl, whip egg whites with a handheld electric mixer set to medium speed until fluffy, about 1 -2 minutes. Gently mix egg whites into the cake batter until thoroughly combined.

Line 9 cups of a 12-cup muffin pan with baking cups and/or spray with nonstick spray. Evenly distribute batter among the 9 cups. Cups will be VERY full --this is okay!

Bake for 15 -17 minutes, until a toothpick inserted into the center of a cupcake comes out fairly clean. Set aside and allow to cool completely.

Once cupcakes have cooled, top each evenly with the frosting and 1 tsp. sprinkles. Chomp chomp!
