Step 1: Preheat and Prepare
Preheat the oven to 350°F (175°C). Grease and line a 9×5-inch loaf pan with parchment paper, leaving some overhang for easy lifting later.

Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together flour, baking soda, and salt until evenly combined. Set aside.

Step 3: Mash the Bananas
In a large bowl, mash the bananas until smooth but slightly chunky. The more overripe the bananas, the better the flavor and moisture.

Step 4: Combine Wet Ingredients
Add melted butter, peanut butter, brown sugar, eggs, and vanilla extract to the mashed bananas. Whisk until the mixture is smooth and creamy.

Step 5: Combine Wet and Dry
Gradually add the dry ingredients to the wet mixture, folding gently with a spatula until just combined. Do not overmix.

Step 6: Add Chocolate & Reese’s Pieces
Fold in the Reese’s pieces and chocolate chips evenly. Reserve a small handful to sprinkle on top for a melty, decorative finish.

Step 7: Pour and Bake
Pour the batter into the prepared loaf pan. Smooth the top, sprinkle the reserved toppings, and bake for 55–65 minutes until a toothpick inserted into the center comes out mostly clean.

Step 8: Cool and Slice
Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
