I love recipes that use common pantry items so I don’t have to look far to create a delicious muffin or baked good. Plus, I get to use up my ripe bananas for something more than banana bread! 

How to make peanut butter banana muffins from scratch

  • Butter – using unsalted butter is best to allow you to control the salt level better. This is where the richness of the muffin shines through.
  • Peanut butter – I use creamy peanut butter to evenly distribute through the batter. You could also use almond butter or another nut butter.
  • Brown sugar – for a soft deeply sweet muffin, brown sugar works best for this recipe. Regular sugar can be substituted if preferred.
  • Other wet ingredients – an egg, vanilla extract, and milk.
  • Dry Ingredients – all-purpose flour, baking powder, baking soda, salt, cinnamon powder, and nutmeg.
  • Add-ins – bananas and chocolate chips


  • Flour – I use all-purpose flour.
  • Brown sugar – light brown sugar has the best flavor, or use dark brown for a much richer topping.
  • Butter – use softened butter to get the best crumble.
  • Peanut butter – creamy or crunchy peanut butter would work for the crumble.
  • Ground cinnamon – adding cinnamon will allow the flavors to match from the batter to the topping.
  • Peanuts – adding chopped peanuts adds texture and portrays a peanut butter muffin perfectly.
  • Chocolate chips – this is optional, but who doesn’t love a chocolatey, crunchy crumble topping? A fun alternative would be peanut butter chips.

  • Milk
  • Powdered sugar

How to make peanut butter banana muffins

I follow a certain method to create the batter for these banana peanut butter muffins. This is how I get soft, evenly mixed muffins that are moist and tender.

Mix the batter

In a medium bowl, microwave the butter and peanut butter until completely melted. Do this in 15-second intervals to avoid overheating the butter.

Once melted, remove the bowl and whisk in the brown sugar until combined.

Follow by whisking in the egg and vanilla. Make sure the butter isn’t too hot before adding the egg.

In a separate bowl, whisk together the dry ingredients. Then lightly mix into the butter-sugar mixture.

Stir in the milk.

Gently fold in the mashed bananas and chocolate chips (if using).

Divide the batter into the muffin cups. 

Make the crumble

Combine the ingredients and then use your hand to squeeze the mixture into large pieces, gently breaking into varying sizes. 

Once you add the batter to the cupcake pan, spread the crumble on top evenly.

Bake until a toothpick comes out clean and you have a nice brown crumble. 

Allow cooling for a few minutes before transferring to a wire rack to finish cooling completely.

Prepare the glaze

In a small bowl, whisk together the peanut butter and milk until it is evenly mixed and smooth.

Add in the powdered sugar and whisk to form a thick glaze. Add a smidge more milk if it is too thick, or alternatively, add more sugar if too thin.

Drizzle over the muffins how you like.

These muffins have the best texture and richness in every bite. From the soft peanut butter muffins with bits of bananas and chocolate chips throughout to the crunchy crumble topping, finished off with creamy peanut butter glaze. There’s so much going on that you’ll just enjoy the simple fact that these are overwhelmingly delicious.

Baker’s Tips for Muffins

I want you to get the best results when you try my recipes so here are a few tips for this peanut butter muffin recipe with bananas and chocolate chips. 

Measure the flour. The most common mistake when baking is not measuring the dry ingredients properly which will always lead to dry baked goods. Ensure that you get the best results by measuring the flour with the dip and fill method.

Use ripe bananas. They don’t have to be overripe like when you make banana bread, but they should be ripe. The riper a banana the sweeter it is. You’ll get the most banana flavor from a ripe one, too.

Don’t overmix the batter. For this muffin recipe, there are a few steps to making the batter. Heating both kinds of butter, add the sugar, whisk in the dry ingredients, and fold in the bananas and chocolate chips.

Once the dry ingredients are added, you want to mix everything until JUST combined so as to not overwork the muffin batter. Doing so may lead to a denser or too crumbly muffin. They may also bake unevenly or have lopsided tops.

Make without the crumble topping. The peanut crumble-topping is a showstopper. But you can easily skip adding this and bake. You’ll find the tops to be similar to a bakery-style muffin with a shiny golden-brown rise.

Make them JUMBO! Use a jumbo muffin pan and increase the baking time. For jumbo muffins, bake for 28-33 minutes, checking for doneness around the 28-minute mark. 

Substitutions and Variations

I love every bit of this muffin recipe with peanut butter and bananas but there are a few ways to make it unique and fit your taste. 

  • Use almond butter – Switch out all of the peanut butter in this banana muffin recipe for almond butter. You can even use slivered almonds instead of chopped peanuts for the crumble.
  • Switch out the chocolate chips – If you use the chocolate chips, try trading them out for white chocolate or peanut butter chips.
  • Add nuts to the muffin batter – For more texture, add some crunchy chopped peanuts into the batter when you add in the mashed bananas. It’ll add an additional texture feature to these peanut butter muffins. Or, you could use chunky peanut butter instead of smooth.
  • Use nut milk instead of regular milk. This is an easy exchange and shouldn’t affect the muffin.
  • Use oil in place of butter. You can swap out the butter for oil without lose of texture. But, the step you need to change is melting the peanut butter and butter. Instead, melt the peanut butter first, then stir in the oil before mixing the brown sugar in.

How do you know when muffins are done baking?

The toothpick method is one of the best and easiest ways to check for the muffin’s doneness. Insert the toothpick into the middle of a muffin while still in the oven. You want it to come out clean or with a few moist crumbs. You can also check if a muffin is done by using a thin knife.

How full do you fill a muffin cup with a crumble topping? 

Even with the crumble topping, fill the cup up to ¾ full. Once it rises the crumble with meld into the batter and forms a rounded top. You shouldn’t have to worry about it overflowing because of the crumble. 

Why is the bottom of my muffins soggy?

Soggy muffin bottoms usually happen when you leave them in the muffin pan too long after baking. The steam gets trapped under the paper liner. To avoid this, remove the muffins to a cooking rack when they are cool enough to handle.

How do I prevent muffin liners from sticking?

Lightly spray the liner with cooking spray, emphasis on the light! Or, skip the liners completely and bake right in the pan using cooking spray.
