  • Total Time: 45 minutes
  • Yield: 6 servings

Ingredients

1 cup mashed overripe banana (about 3 medium bananas)

½ cup creamy natural peanut butter

2 large eggs (or flax eggs for vegan)

¾ cup unsweetened dairy-free milk

2 tbsp maple syrup

1 shot espresso (optional)

⅓ cup unsweetened cocoa powder

¼ cup unflavored collagen peptides (optional)

1½ cups gluten-free rolled oats

1 tsp baking powder

Pinch of salt

½ cup chocolate chips + extra for topping

Instructions

  1. Preheat oven to 350°F (175°C) and lightly grease an 8×8-inch baking dish.
  2. Mash bananas in a large bowl until smooth.
  3. Stir in peanut butter, eggs, dairy-free milk, maple syrup, and espresso (if using).
  4. Add cocoa powder, collagen peptides (if using), rolled oats, baking powder, and salt. Mix until combined.
  5. Fold in chocolate chips.
  6. Pour mixture into the prepared baking dish and spread evenly.
  7. Top with extra chocolate chips.
  8. Bake for 30–35 minutes, until set and a toothpick inserted comes out mostly clean.
  9. Cool slightly before slicing and serving.

Notes

  • Swap peanut butter for almond butter for a different flavor.
  • Use chopped dark chocolate instead of chips for extra richness.
  • Add nuts or shredded coconut for added texture.
  • Make it vegan by using flax eggs and dairy-free chocolate chips.
  • Store leftovers in the fridge for up to 5 days or freeze individually for longer storage.
