Ingredients
- 1 ½ cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- ½ teaspoon salt
- 3 bananas, peeled and mashed
- ¾ cup granulated sugar
- 1 large egg, beaten
- â…“ cup unsalted butter, melted
- 1 cup fresh blueberries
How To Make Banana Blueberry Crumb Muffins
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). Prepare a muffin tin by lining it with paper liners or greasing it lightly with non-stick spray.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt until combined. This will ensure that all the leavening agents are evenly distributed throughout your dry ingredients.
Step 3: Prepare the Wet Ingredients
In a large bowl, mash the bananas until smooth. Add the granulated sugar and the beaten egg to the mashed bananas, mixing until everything is well combined. Pour in the melted unsalted butter and stir until the mixture is homogenous.
Step 4: Combine Dry and Wet Ingredients
Slowly add the dry ingredients to the wet mixture, stirring gently. Be careful not to overmix; a few lumps are perfectly fine!
Step 5: Fold in Blueberries
Gently fold in the fresh blueberries into the batter. This step ensures that the blueberries are evenly distributed without breaking them apart and coloring the entire batter.
Step 6: Fill Muffin Cups
Spoon the muffin batter into the prepared muffin cups, filling each about two-thirds full. This will give the muffins room to rise without overflowing.
Step 7: Prepare the Crumb Topping (Optional)
In a small bowl, mix together ¼ cup of additional flour, 2 tablespoons of granulated sugar, and 2 tablespoons of melted butter until crumbly. Sprinkle the crumb topping evenly over the muffins before placing them in the oven.
Step 8: Bake
Bake the muffins in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean. Keep an eye on them, as baking times can vary depending on your oven.
Step 9: Cool and Enjoy
Once they are done baking, remove the muffins from the oven and allow them to cool in the pan for about 5 minutes before transferring them to a wire rack to cool completely. Serve warm and enjoy!
Expert Tips
- Use overripe bananas for maximum sweetness and moisture; the blacker, the better!
- For an extra pop of flavor, consider adding a teaspoon of vanilla extract to the banana mixture.
- If using frozen blueberries, don’t thaw them—they can make the batter too wet. Add them straight from the freezer.
- Store any leftover muffins in an airtight container to keep them fresh longer.
Variations and Customizations
- Swap in whole wheat flour for a healthier option, which will add a nice texture and flavor.
- Add chopped nuts like walnuts or pecans for added crunch and nuttiness.
- Incorporate spices like cinnamon or nutmeg for a warm, cozy flavor twist.
- Substitute half of the blueberries with chocolate chips for a sweet indulgence.
How to Store Leftovers
To keep your Banana Blueberry Crumb Muffins fresh, store them in an airtight container at room temperature for up to 3 days. If you’d like them to last longer, consider freezing them. To freeze, wrap each muffin tightly in plastic wrap, then place them in a freezer-safe bag. They can be kept in the freezer for up to 3 months. When you’re ready to enjoy one, simply thaw it overnight in the refrigerator or pop it in the microwave for a quick warming.
FAQ
Can I use frozen blueberries in this recipe?
Absolutely! Frozen blueberries work just fine, just be sure to add them directly from the freezer without thawing to prevent excess moisture.
How can I tell when my muffins are done baking?
The best way to check for doneness is to insert a toothpick into the center of a muffin. If it comes out clean or with a few crumbs attached, they are ready to be taken out of the oven.
Can I make these muffins ahead of time?
Yes! These muffins can be made ahead of time and stored in an airtight container. You can also freeze them for later enjoyment.
What can I use instead of butter?
If you prefer a dairy-free option, coconut oil or a vegetable oil can be used in place of unsalted butter. Just melt it before adding it to your batter.
