Banana crumb muffins are moist banana muffins that are topped with a sweet crumb topping. These banana streusel muffins make a great breakfast or dessert.

We almost always end up with a few overripe bananas. I love turning the bananas no one wants to eat into things like banana bread, banana waffles, and these banana crumb muffins.
These muffins are moist banana muffins that are topped with a sweet crumb/streusel topping. They’re easy to mix by hand (and I recommend making them that way), and they take less than 30 minutes total from start to finish to make.

Ingredient notes and substitutions
- Butter: I use salted butter in this recipe. If you’re using unsalted butter, add a pinch of salt to the topping, and increase the salt in the muffins by 1/4 teaspoon.
- Bananas: I like to use bananas that are equal parts speckled and yellow in this recipe.
- Brown sugar: I use light brown sugar, but dark brown sugar also works well in this recipe.
How to make banana crumb muffins
Here you’ll find step-by-step photos showing how to make this recipe. The full recipe, including ingredients, is given below.

Step 1: To make the crumb topping, stir the flour, sugar, and cinnamon together.

Step 2: Cut in the butter until it resembles coarse crumbs.
Step 3: Chill until ready to use.Â

Step 4: Mash the banana in a large mixing bowl.
Step 5: Stir in the melted butter and sugars until well-combined.

Step 6: Add the eggs and the vanilla and stir in until combined.

Step 7: Add the dry ingredients and mix in just until combined.

Step 8: Divide the batter between the prepared muffin tin cups.

Step 9: Sprinkle with crumb topping.
Step 10: Bake for 15 minutes, or until done.

Recipe Tips!
- Crumb topping: The butter should be at room temperature so that it mixes in easily. However, because it’s warmer, it’s important to chill the topping so that it doesn’t run while baking. Also, you can press it to get a clumpier topping. The clusters tend to hold their shape a little better as the muffins bake.
- Mixing: I recommend mixing this muffin batter by hand. It’s easy to mix, and mixing the batter by hand helps to avoid overmixing.
- Baking: The muffins should spring back when lightly pressed. Also, a wooden toothpick inserted in the center should come out clean.

Storage
These muffins can be stored in an airtight container at room temperature. They will keep for up to 3 days when properly stored.
