• 1 cup bread flour
• 2 tablespoons white sugar
• 1 teaspoon baking powder

• 2 tablespoons maple syrup (optional)
• 2 tablespoons melted butter

2. Whisk flour, sugar, baking powder, baking soda, and salt together in a bowl.
3. Stir buttermilk, egg, syrup, and butter together in a separate large bowl until just combined; add flour mixture and stir with a spoon until just combined and no lumps remain. Fold peanut butter pieces into the mixture; spoon into the prepared muffin cups.
