Preheat your oven:
Preheat the oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan or line it with parchment paper.

Mix the dry ingredients:
In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.

Prepare the wet ingredients:
In a large mixing bowl, combine the mashed bananas, peanut butter, melted butter, and sugar. Stir until smooth. Add the eggs and vanilla extract, mixing until fully combined.

Combine wet and dry ingredients:
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.

Add Reese’s and chocolate chips:
Fold in the chopped Reese’s Pieces or mini Reese’s cups and the chocolate chips until evenly distributed throughout the batter.

Bake:
Pour the batter into the prepared loaf pan and smooth the top with a spatula. Bake for 55-65 minutes, or until a toothpick inserted into the center comes out clean.

Cool and serve:
Allow the banana bread to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. Slice and enjoy!
