Ingredients

Scale
  • 2 cups old-fashioned rolled oats (200g)
  • 1 cup natural peanut butter, creamy or chunky (250g)
  • 1 large ripe banana, mashed (about 1/2 cup or 120g)
  • 1/3 cup honey or pure maple syrup (80ml)
  • 1 large egg (or 1 flax egg for vegan: 1 tbsp ground flaxseed + 2.5 tbsp water, mixed and rested 5 min)
  • 1 tsp vanilla extract (5ml)
  • 1 tsp baking powder (4g)
  • 1/4 tsp salt (1g)
  • 1/2 cup dark chocolate chips or chunks (85g)
  • Optional: chopped nuts (pecans, almonds), shredded coconut, chia seeds, flaky sea salt for topping

Instructions

  1. Preheat the oven to 350°F (175°C). Line a 12-cup muffin pan with paper or silicone liners, or lightly grease each cup.
  2. In a large bowl, combine oats, baking powder, and salt. Stir to combine.
  3. In a medium bowl, mash the banana until mostly smooth. Add peanut butter, honey or maple syrup, egg (or flax egg), and vanilla extract. Stir until fully incorporated.
  4. Pour the wet mixture into the oats. Mix well with a sturdy spatula or wooden spoon until all the oats are coated and the mixture is thick. If too dry, add a splash of milk.
  5. Gently fold in chocolate chips or chunks, reserving a few for topping if desired.
  6. Divide the mixture evenly among the 12 muffin cups, filling each about 3/4 full. Press down gently to compact and flatten the tops.
  7. Bake for 15-18 minutes, or until set and slightly golden around the edges. A toothpick inserted in the center should come out mostly clean.
  8. Remove from the oven and let cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
  9. Enjoy warm or cool. Store leftovers in an airtight container in the fridge for up to 1 week, or freeze for up to 3 months.

Notes

For best texture, use runny natural peanut butter and rolled oats. To make vegan, use a flax egg and maple syrup. For gluten-free, use certified gluten-free oats. Add-ins like nuts, coconut, or chia seeds can boost nutrition and flavor. Don’t overbake—cups firm up as they cool. Let cool completely before removing from liners to prevent crumbling.
