Powdered peanut butter gives these apple peanut protein muffins great texture and flavor with 21g protein per muffin! Naturally gluten free. Makes 3 muffins.
Add protein powder, baking powder, and cinnamon. Mix well.
Fold in chopped apple and peanuts.
Spoon batter into 3 large silicone muffin cups.
Bake for 24 minutes, or until firm and a toothpick comes out clean.
Let cool, and enjoy! Store extras in the refrigerator.
Notes
A note about substitutions: because each type of protein powder has a distinct flavor and texture when baked, I would not recommend using whey protein or other vegan powders here. You might try using peanut flour in place of the powdered peanut butter, but you'd probably want to add a sweetener. (See my Recipe Basics video for examples of what goes wrong when you use the wrong protein powder.)
