This banana crumb muffin is a spin off of a recipe I got from my dear friend Sarah. She makes this killer banana crumb bread, that we LOVE and I just couldn’t resist making them into muffins.

We buy bananas by the dozen in our house. We use them daily in protein smoothies, and also just to eat because bananas are so dang good. Occasionally we will get some that last long enough to become over-ripe, and then I know it’s time for some sort of delicious banana baked good! The questions is, do I make our classic banana bread (or any of our banana bread recipes, I am obsessed with banana breads!) , or these bakery style banana crumb muffins? The choice seems impossible! But there is something so convenient about muffins!

Muffins are a great grab-and-go breakfast, after school snack or individual dessert. These muffins have real bold banana flavor and are so tender. My kids go bananas for these banana muffins!

What’s the Secret to a Streusel Crumb Topping?

Salt is the secret to the best crumb topping! I’m serious, adding a little salt makes all the difference as it’s perfectly sweet with a hint of mouthwateringly delicious saltiness!

Why Use Over-Ripe Bananas?

The perfect bananas for this banana muffin recipe (or any baked good that uses bananas) are really yellow in color with brown spots freckled all over them. They can even be turning brown. Very ripe bananas are sweeter because the starches in the banana have begun changing into sugar. Don’t throw those bananas away people! They are the best for baking!

Other Ways to Use Ripe Bananas

Besides all the delicious banana quick breads, there are so many delicious ways to use ripe bananas. Here are a few ideas:

How to Make Banana Crumb Muffins

One of the things I love about muffins is that they are so easy. Here are the basic steps:

  1. Make the topping. I like to get my fingers into it to mix it all together, but feel free to use a fork.
  2. Combine all the wet ingredients in a stand mixer.
  3. Combine all the dry ingredients in a separate bowl.
  4. Mash the bananas in another dish.
  5. Add the wet ingredients to the dry ingredients and mix until smooth and then fold in the mashed bananas.
  6. Fill the muffin cups or liners about 2/3 full and then bake partially, add the crumb topping and then finish baking.

The instructions in full detail can be found in the recipe card down below.

How to Mash Bananas

I like to put my bananas on a large plate and mash them with a fork. It also works just fine in a bowl or using a potato masher. This leaves the bananas chunky, which I like. I don’t recommend putting them in a blender or food processor because it makes the bananas too thin. You want some good chunks left!

Banana Muffin Variations

These muffins with the crumb topping is all you really need, but if you want to add more flavors or a little more texture, you could add chocolate chips, walnuts, pecans, peanut butter chips, almonds, etc. to the batter before baking. Any of the nuts would also go great in the topping!

Storage Tips for Banana Muffins

  • Storing: Banana bread muffins should be tightly wrapped or kept in an air tight container. They will keep 2-3 days at room temperature. If you want them to last a little longer, store them in the refrigerator. They will keep for up to a week in the fridge.
  • Freezing: Muffins will keep 2-3 months in the freezer. Wrap the muffins well in plastic wrap, foil or place in a freezer bag and then place it in the freezer. Set them out on the counter for a half hour or so to let them come to room temperature before serving.
  • Warning: The crumb topping will lose it’s crunchiness once the muffins have been refrigerated or frozen.
