Moist banana muffins topped with a sweet crumb topping. These banana streusel muffins make a great breakfast or dessert.
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.
How to make banana crumb muffins
To make the crumb topping, stir the flour, sugar, and cinnamon together. Cut in the butter until it resembles coarse crumbs.
Chill until ready to use. Mash the banana in a large mixing bowl.
Stir in the melted butter and sugars until well-combined. Add the eggs and the vanilla and stir in until combined.
Add the dry ingredients and mix in just until combined. Divided the batter between the prepared muffin tin cups and sprinkle with crumb topping.
- 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.
- Bananas: I like to use bananas that are equal parts speckled and yellow in this recipe.
- 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.
These muffins can be stored at room temperature in a resealable container for up to 3 days.
