Preheat oven to 350°F (175°C). Grease and flour a 9×5 inch loaf pan.
Whisk together flour, baking soda, cinnamon, and salt in a bowl.
In another bowl, cream butter and sugar until light and fluffy. Beat in eggs, one at a time.
Mix in mashed bananas, peanut butter, and vanilla extract.
Gradually add the flour mixture to the wet ingredients, stirring until combined.
Fold in the chopped Reese’s peanut butter cups.
Pour batter into the prepared loaf pan. Bake for 60-70 minutes or until a toothpick inserted into the center comes out clean.
Let it cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.
