Step 1

Preheat oven to 350°F (180°C) and prepare a muffin mold with muffin liners. Make sure you grease the liners to prevent the cupcakes from sticking.

Step 2

In a large bowl, mash the banana then combine with Greek yogurt, egg, maple syrup, vanilla extract and a pinch of salt. Stir well until you get a smooth mixture.

Step 3

Add into the wet mixture oat flour, protein powder and baking powder. Stir the ingredients together while pouring in the milk gradually. Start with about 3 tbsp (45 ml) and add as much as ⅓ cup (80 ml) of milk until the batter becomes smooth, but not too liquid. This depends on the type of protein powder that you are using.

Step 4

Fold through the chocolate chips or any mix-in you'd like.

Step 5

Fill ⅔ of each muffin liner with the batter, sprinkle with more chocolate chips and bake in hot oven for 20 to 25 minutes. Make sure you do not overbake the muffins. They are ready when a toothpick inserted into the center comes out clean.

Step 6

Remove your protein muffins from the oven and let cool over a baking rack for about 15 minutes.
