Ingredients Needed

- Sour Cream: Helps keep the muffins moist and soft. Greek yogurt can be used instead.
- Peanut Butter: For best results, I recommend using a creamy peanut butter rather than something natural or old-fashioned.
- Mashed Bananas: Choose overripe, brown bananas for the best flavor and texture. Frozen bananas can be used; just drain any extra water once they thaw.
- Mini Chocolate Chips: I recommend using semi-sweet chocolate chips to prevent your muffins from becoming overly sweet.
How to Make Easy Peanut Butter Banana Muffins

- Step 1: In a large mixing bowl, whisk together dry ingredients (flour, cinnamon, baking powder, baking soda, and salt).
- Step 2: In a separate large bowl, combine vegetable oil, vanilla, egg, and brown sugar until just combined.

- Step 3: Mix in the peanut butter, milk, and sour cream.
- Step 4: Fold the dry ingredients into the wet ingredients until a batter forms. Avoid overmixing.

- Step 5: Fold mashed bananas and mini chocolate chips into the batter.
- Step 6: Divide batter into 12 liners in a muffin tin, then bake at 425 degrees for 5 minutes. Reduce heat to 350 degrees and bake another 15 minutes.

Recipe Tips
- Insert a toothpick into the center of a muffin to test for doneness. They're good to go if the toothpick comes out clean.
- Avoid opening the oven between temperature adjustments.
- Try not to overmix the muffin batter, as this can lead to tougher or denser muffins.
- If you want to serve these as a dessert rather than a snack or as breakfast muffins, milk chocolate chips can be used for some additional sweetness.
- Peanut butter chips also work to double down on the nutty flavor.

Peanut Butter Banana Muffins FAQ's
I recommend using overripe, brown bananas as they'll add lots of moisture and sweet flavor.

No, you can omit the chocolate chips if you want to simplify the flavors in these muffins!
