Step 1

Preheat the oven to 350 degrees F. Grease a 7-inch x 11-inch pan with nonstick cooking spray.

Step 2

In a large bowl, whisk the mashed banana, eggs, plain whole milk greek yogurt, milk, maple syrup, and vanilla until well combined. Add in the power cakes mix and stir until just combined and no dry mixture remains. Next, use a wooden spoon to mix the salted butter into the batter until well incorporated. Gently fold the blueberries into the batter. Pour the batter into the pan and use a rubber spatula to smooth the top.

Step 3

Bake for 30 to 35 minutes until a tester comes out clean. Allow to cool for 10 minutes then cut into slices. Top each slice with butter or yogurt and a drizzle of maple syrup, if desired.
