Preheat your oven to 350°F (175°C). Line muffin tin with parchment paper or grease lightly.

In a mixing bowl, peel and mash about 2-3 ripe bananas until smooth.

Add ½ cup of peanut butter and ¼ cup of honey (or maple syrup) to the mashed bananas. Whisk until smooth.

Combine 1 cup of oats and 1 teaspoon of baking powder in a separate bowl. Gradually fold into the wet mixture.

Add 2 eggs to the batter and mix until fully incorporated. Add any optional mix-ins if desired.

Scoop the batter into the muffin tin, filling each cup about 2/3 full.

Bake for 15-20 minutes until golden brown and a toothpick comes out clean.

Let the muffins cool in the tin for 5 minutes before transferring to a wire rack.
