Found this recipe on BuzzFeed and had to try - definitely a new favorite post-workout snack!
1 ½ cups nonfat Greek yogurt
3 large eggs
¼ cup unsalted butter, melted
¼ cup granulated sugar
½ cup all-purpose flour
¾ cup oat bran
1 ½ teaspoons baking powder
½ teaspoon kosher salt
1 cup chocolate flavored protein powder of choice
¼ cup unsweetened cocoa powder
¼ cup dark chocolate chips (I used the Ghirardelli 60% Cocoa - highly recommended!)
In a medium mixing bowl, beat together eggs, yogurt, and melted butter. Add the granulated sugar and whisk to combine. In a large mixing bowl, stir together flour, oat bran, baking powder, protein powder, and cocoa powder, just to combine. Pour the wet ingredient over the dry ingredients and stir together until the mixture is a thick, uniform batter. Add chocolate chips and stir to evenly distribute the chips in the batter.
Spray a 12-cup muffin tin with nonstick cooking spray and divide the batter evenly among the muffin cups. Bake the muffins in the preheated oven until puffed and cooked through, 18 to 21 minutes. Cool completely before serving.
