Peanut Butter Banana Muffins have a surprise inside and are so fluffy and moist. These easy banana muffins are filled with creamy peanut butter and topped with caramelized peanuts.
Peanut Butter Banana Muffins are easy to make and perfect for breakfast, brunch, or as an afternoon snack. They are inspired by one of my favorite afternoon snacks – banana slices topped with peanut butter. Have you tried this yet? It’s so tasty and easy.
Who doesn’t love the combination of sweet and slightly salty?! Bananas and peanut butter go so well together! It doesn’t have to be chocolate and peanut butter all the time, this combination is as tasty. But you have to promise me to check out my Peanut Butter Brownie Bars after trying this recipe.
These muffins are stuffed with creamy peanut butter which makes them super delicious and they’re so moist because of all the bananas. Creaming the butter and sugar makes them super fluffy and tender. That’s how I love my muffins!
Julia’s Tips and Tricks
- Overripe bananas: You want to use over-ripened bananas with black spots for this recipe. They are easier to mash and sweeter. If your bananas aren’t ripe yet you can bake them in a 300°F oven for 30-40 minutes to make them softer and sweeter.
- Muffin Liners: Use muffin liners for this recipe! The muffins will come easier out of the pan and are easier to store. These muffins are super moist so they are more likely to stick to the pan when you don’t use liners.
- Mixing: Don’t overmix the batter! This is important for every muffin recipe. To ensure that your muffins are light and fluffy mix the dry ingredients with the wet ingredients until just barely combined, and no more dry flour is visible.
- Cooling: Don’t let the muffins cool down in the muffin tin! The hot muffin tin will continue to bake the muffins and you might end up with drier muffins. Give the muffins a couple of minutes to cool off, then remove them and transfer them to a cooling rack.

Tools Used in the Making of these Peanut Butter Banana Muffins:
Ice Cream Scoop: This scoop is perfect for portioning the muffins and quickly scooping without mixing the batter too much.
