# What You Need:

→ Dry Ingredients

01 - 1 1/2 cups all-purpose flour
02 - 1 teaspoon baking powder
03 - 1/2 teaspoon baking soda
04 - 1/2 teaspoon salt

→ Wet Ingredients

05 - 2 large ripe bananas, mashed
06 - 1/2 cup creamy peanut butter
07 - 1/2 cup brown sugar, packed
08 - 1/4 cup vegetable oil or melted butter
09 - 2 large eggs
10 - 1 teaspoon vanilla extract
11 - 1/2 cup milk

→ Optional Add-ins

12 - 1/2 cup chocolate chips or chopped peanuts

# How to Make It:

01 - Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners or lightly grease with cooking spray.
02 - In a medium bowl, whisk together flour, baking powder, baking soda, and salt until well blended.
03 - In a large bowl, mash bananas thoroughly. Add peanut butter, brown sugar, oil, eggs, and vanilla extract. Mix until smooth and incorporated.
04 - Stir milk into the wet mixture until fully combined.
05 - Add dry ingredients to wet ingredients. Fold gently with a spatula until just combined—do not overmix or muffins will become tough.
06 - Gently fold in chocolate chips or chopped peanuts if desired.
07 - Divide batter evenly among prepared muffin cups, filling each about 3/4 full.
08 - Bake for 18-22 minutes until a toothpick inserted in the center comes out clean or with just a few moist crumbs.
09 - Let muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

# Expert Tips:

01 -
  • These muffins stay incredibly moist for days, thanks to those overripe bananas doing all the heavy lifting
  • The peanut butter isn't just an aftertaste—it's woven through every single bite like a warm hug
02 -
  • Over-mixing is the enemy here—those lumps are going to bake out into fluffy perfection
  • Room temperature ingredients mix together so much more smoothly than cold ones
03 -
  • Use an ice cream scoop for mess-free, perfectly portioned muffins every single time
  • Let them cool completely before storing, or the trapped steam will make them soggy
