37 Calorie Brownies

Who doesn't love chocolate? Tastes & Treasures cookbook has awesome recipes for brownies and chocolate, and I have tried them all. Perhaps this one should be in the book too.
I wanted to try this one since it was so different.

37 CALORIES BROWNIES
Ingredients:
3/4 cup nonfat Greek yogurt (I used vanilla yogurt)
1/4 cup skim milk
1/2 cup Cocoa powder
1/2 cup Old fashioned rolled oats (like Quaker)
1/2 cup Truvia (or any natural/stevia based sweetener that pours like sugar)
1 egg
1/3 cup applesauce
1 teaspoon baking powder
1 pinch salt

Directions:
Preheat the oven to 400°F. Grease a square baking dish (I used 8"x8"). Combine all ingredients into a food processor or a blender, and blend until smooth (about 1 minute). Pour into the prepared dish and bake for about 15 minutes. Allow to cool completely before cutting into 9 large squares.
