What You’ll Need to Bake These Muffins
Gathering your ingredients is the first step to baking these delicious muffins. You’ll need items for both the delightful crumb topping and the moist muffin batter itself. Specific measurements are key for the best results.
For the delicious streusel topping you will sprinkle over the batter:
- Packed light brown sugar
- All purpose flour
- Ground cinnamon
- Cold unsalted butter (cut into small pieces)
And for the moist, flavorful muffin batter:
- Granulated sugar
- Melted unsalted butter
- Mashed ripe banana (the spottier, the better)
- A large egg (ideally at room temperature)
- Pure vanilla extract
- All purpose flour
- Baking powder
- Baking soda
- Ground cinnamon
- Fine sea salt
Getting the Right Amount of Ripe Bananas
Ensuring you have the correct amount of mashed banana is really important for the texture and moisture of your muffins. The best way I’ve found to do this is to mash your overly ripe bananas in a separate bowl first. Then, measure out the specific amount the recipe calls for, whether it’s by volume like 1 ½ cups or by weight like 345 grams. While most recipes suggest 3 or 4 medium bananas, measuring after mashing gives you accuracy and guarantees consistent results every time. Using bananas that are very ripe, with lots of brown spots or even almost completely brown skins, will give you the most intense banana flavor and natural sweetness.

How to Create These Wonderful Bakery-Style Muffins
Baking these banana crumb muffins from scratch is a simple and rewarding process. You’ll want to follow the full recipe details for precise measurements and timing. The basic steps are easy to follow, ensuring delicious results with minimal fuss. A key tip for achieving light, tender muffins is to avoid overmixing the batter once the dry ingredients are added.
Here is a simple overview of the process for making these muffins:
- Get Ready: Preheat your oven and prepare your muffin pan. You can line it with paper liners or grease the cups thoroughly with nonstick cooking spray.
- Make the Crumb Topping: In a small bowl, combine the brown sugar, flour, and cinnamon. Add the cold butter pieces. Use a fork or your fingers to blend these ingredients together until the mixture looks like coarse crumbs. Set this topping aside for later.
- Prepare the Muffin Batter: In a large bowl, beat the granulated sugar and melted butter together. Stir in the mashed bananas, the egg, and the vanilla extract. Mix these wet ingredients well.
- Add the Dry Ingredients: Introduce the flour, baking powder, baking soda, cinnamon, and salt to the bowl with the wet ingredients.
- Combine Carefully: Using a rubber spatula, gently fold the dry ingredients into the wet mixture. Stop mixing as soon as you no longer see any dry flour spots. Do not overmix the batter.
- Fill the Cups: Divide the batter evenly among the prepared muffin cups. Fill each cup about two-thirds full. You can use about 3 tablespoons of batter per standard muffin cup.
- Add the Topping: Spoon the prepared crumb topping generously over the batter in each muffin cup before they go into the oven.
- Bake: Place the pan in the preheated oven. Bake for the recommended time, testing for doneness by inserting a toothpick into the center of a muffin. It should come out clean or with just a few moist crumbs.
- Cool: Let the muffins cool in the pan for a few minutes on a wire rack. Then, carefully remove them from the pan to finish cooling completely on the rack.

Storing Your Banana Crumb Muffins Properly
You’ve baked a batch of amazing muffins, and now you want to keep them fresh and delicious for as long as possible. Proper storage is key. One trick I use to help keep the tops from getting soggy is to place a slice of plain bread or a few saltine crackers in the storage container with the muffins; they help absorb excess moisture.
To store them, first make sure the muffins are completely cooled. Line an airtight container with paper towels on the bottom. Place the cooled muffins in a single layer in the container. Add another layer of paper towels on top before sealing the lid tightly. Check the paper towels occasionally and replace them if they become damp. Stored this way on the counter, the muffins usually stay fresh for up to four days.
For longer storage, freezing is a great option. Once the muffins are completely cooled, wrap each individual muffin tightly in plastic wrap. Then, place the wrapped muffins in a freezer bag. You can keep them in the freezer for up to three months.
To enjoy a frozen muffin, you can simply thaw it at room temperature. If you want that warm, fresh-baked feel, wrap the frozen muffin in aluminum foil and warm it in a 300 degree Fahrenheit oven for about 12 to 15 minutes, until it is heated through.

My Best Tips for Perfect Banana Crumb Muffins
I’ve learned a few things over the years that really make a difference when baking banana muffins, especially these wonderful crumb-topped ones.
- Use Very Ripe Bananas: This is perhaps the most important tip for achieving fantastic flavor. The natural sugars and intense banana taste from overly ripe bananas (the ones covered in brown spots) are what make these muffins truly special. If you have bananas that are getting too ripe but aren’t ready to bake, you can freeze them peel-on. Just thaw them on the counter or in the microwave when you are ready to bake.
- Do Not Overmix: This is crucial for tender muffins. Once you add the dry ingredients to the wet mixture, switch to a rubber spatula. Gently fold everything together only until the dry streaks of flour disappear. Overmixing develops gluten, which can result in tough, dense muffins instead of the light, airy ones you want.
- Portion Uniformly: For muffins that bake evenly and look beautiful, try using a scoop to portion your batter. A size 20 ice cream scoop (which holds about 3 tablespoons) is perfect for filling standard muffin cups consistently. This ensures all your muffins are roughly the same size and cook at the same rate.
- Test for Doneness Correctly: Knowing when your muffins are perfectly baked is important. Insert a toothpick into the center of one of the muffins. If it comes out clean or with just a few moist crumbs attached, they are ready to come out of the oven. If it comes out with wet batter, they need a little more time.
Common Questions About Banana Crumb Muffins
Here are answers to some questions people often ask about baking these delicious muffins.
Yes, absolutely. Thaw them first, drain off any excess liquid, and then measure the required amount of mashed banana for the recipe. Very ripe frozen bananas work wonderfully.
The most common reason for tough muffins is overmixing the batter after the dry ingredients are added. Mix only until the flour is just combined.
The riper, the better. Look for bananas with lots of brown spots or even entirely brown skin. They are sweeter and easier to mash, providing the best flavor and moisture.
Yes, you can gently fold in about half a cup to one cup of chopped nuts (like walnuts or pecans) or chocolate chips into the batter just before portioning.
Stored properly in an airtight container at room temperature, they usually stay fresh for about 3 to 4 days.
Yes, the recipe can be adapted for mini muffins. The baking time will be shorter, typically around 13 to 15 minutes.

Perfectly sweet, wonderfully tender, and incredibly simple to whip up, they’re an irresistible addition to your baking repertoire—forget the bakery and enjoy a warm, homemade batch instead!
Ingredients
For the Crumb Topping
- ⅓ cup (67 grams) packed light brown sugar
- 2 tablespoons (16 grams) all purpose flour
- ⅛ teaspoon (less than 1 gram) ground cinnamon
- 1 tablespoon (14 grams) cold unsalted butter, cut into small pieces
For the Muffins
- ¾ cup (150 grams) granulated sugar
- ⅓ cup (76 grams) unsalted butter, melted
- 1 ½ cups (345 grams) mashed ripe banana (from about 3–4 medium bananas)
- 1 large egg
- 1 teaspoon (5 ml) pure vanilla extract
- 1 ½ cups (182 grams) all purpose flour
- 1 teaspoon (4 grams) baking powder
- 1 teaspoon (5 grams) baking soda
- ½ teaspoon (1 gram) ground cinnamon
- ½ teaspoon (3 grams) fine sea salt
Instructions
- Preheat your oven to 375° F (190° C). Line a standard muffin pan with paper liners or grease the cups well with nonstick cooking spray.
- Make the crumb topping. In a small bowl, combine the brown sugar, flour, and cinnamon. Add the cold butter pieces. Use a fork, pastry blender, or your fingers to mix everything together until the mixture resembles coarse crumbs. Set this topping aside.
- Prepare the muffin batter. In a large bowl, use an electric mixer to beat the granulated sugar and melted butter together. Add the mashed bananas, egg, and vanilla extract. Mix on medium speed until everything is combined, stopping to scrape down the sides of the bowl as needed.
- Add the dry ingredients to the bowl. This includes the flour, baking powder, baking soda, cinnamon, and salt.
- Using a rubber spatula, gently fold the dry ingredients into the wet banana mixture just until they are combined. Be careful not to overmix the batter. Stop folding as soon as you no longer see any dry flour spots.
- Divide the batter evenly among the prepared muffin cups. Fill each cup about two-thirds to three-quarters full, or use roughly 3 tablespoons of batter per cup for standard-sized muffins.
- Spoon the prepared crumb topping over the batter in each muffin cup before baking.
- Bake in the preheated oven for 15 to 20 minutes. Check for doneness by inserting a toothpick into the center of a muffin. It should come out clean or with just a few moist crumbs attached.
- Let the muffins cool in the pan on a wire rack for several minutes before carefully removing them from the pan to cool completely.
Notes
- Bananas For the best flavor and texture, make sure your bananas are very ripe. Mash them in a separate bowl first and then measure out 1 ½ cups or 345 grams to ensure you have the correct amount.
- Flour Measurement Using a digital scale to measure flour is highly recommended for accurate results. If you don’t have a scale, spoon the flour into your measuring cup and level it off with a knife. Do not scoop flour directly with the measuring cup, as this compacts it and can result in using too much.
- Mixing Dry Ingredients Once you add the flour mixture, switch to a rubber spatula and fold gently. Overmixing develops gluten, which can lead to tough muffins. Mix only until the dry ingredients disappear.
- Portioning Using a #20 ice cream scoop helps create consistently sized muffins.
- Other Sizes
- Mini Muffins yield 22-27 muffins. Bake time is about 13-15 minutes.
- Large Muffins yield 6-8 muffins. Bake time is about 23-25 minutes.
- One 1 pound loaf uses this batter and yields 8-10 servings. Bake time is about 44-47 minutes.
- Storage To help muffins stay fresh longer, you can store them with a slice of plain bread or a few saltine crackers to absorb extra moisture. Place cooled muffins in a container with paper towels on the bottom and top. Change the paper towels if they become damp. For longer storage, wrap individual cooled muffins tightly and freeze them in a freezer bag for up to 3 months. Reheat frozen muffins by thawing them or wrapping them in foil and baking at 300°F (150°C) for 12-15 minutes.
