Ingredients

• 2 1/2 cups old-fashioned rolled oats
• 2 scoops (about 1/2 cup) vanilla protein powder
• 1 1/2 tsp baking powder
• 1 1/2 tsp ground cinnamon
• 1/2 tsp kosher salt
• 3 medium (about 1 1/4 cups) ripe bananas, mashed
• 2 large eggs
• 1 3/4 cups unsweetened almond milk or dairy milk
• 1/4 cup maple syrup
• 2 tsp vanilla extract
• 1/2 cup chopped walnuts or pecans
• 1/3 cup dark chocolate chips (optional)

Instructions

1. 1Preheat the oven to 375°F. Lightly grease an 8×8-inch or 9×9-inch baking dish with cooking spray or butter.
2. 2In a large bowl whisk the oats, protein powder, baking powder, cinnamon, and salt until evenly combined and no protein-powder clumps remain.
3. 3In a separate bowl mash the bananas until mostly smooth with a few small chunks. Whisk in the eggs, milk, maple syrup, and vanilla until fully blended.
4. 4Pour the wet mixture into the dry ingredients and stir with a spatula until every oat is moistened; the batter will be thick but pourable. Fold in half the nuts and optional chocolate chips.
5. 5Scrape the batter into the prepared dish and smooth the top. Sprinkle remaining nuts (and chips) evenly over the surface and gently press them in.
6. 6Bake 32–38 minutes until the center is set, the edges are golden brown, and a toothpick inserted in the middle comes out with just a few moist crumbs. The top should spring back lightly when touched.
7. 7Cool in the pan on a wire rack for at least 10 minutes so slices hold together. Cut into 6 squares.
8. 8Serve warm as-is, or with a spoonful of Greek yogurt and an extra drizzle of maple. Leftovers keep covered in the fridge up to 5 days; reheat individual portions 45–60 seconds in the microwave.
