Preheat the oven to 350 and put liners in your mini muffin tin. This recipe makes 36 servings, but my mini muffin tin only has 24 holes...so I did 2 batches.

In a large bowl, mix egg whites, water, applesauce and brownie mix until well blended. I did this with a spoon by hand, so as to not over mix.

Pour mixture into muffin liners, filling almost to the top.

Bake brownie bites for about 12-15 minutes or until a toothpick inserted into the middle of one comes out clean.

Remove brownie bites from oven and cool completely. Dust with powdered sugar before serving.
