There’s nothing better than waking up on a Sunday morning and filling the house with the delicious smell of banana nut muffins! You’re sure to wake up some late snoozers when you whip up some of these sweet muffins. Not only are these super simple to make, but they only take a few minutes to cook. I love making these when the weather starts to get chilly outside because I can use the oven to warm up the kitchen.

Use Up Overripe Bananas the Easy Way 

Here’s my trick for always being ready to bake: when your bananas start to turn brown, just tuck them into the freezer, peel and all! The skin may darken, but the banana inside stays perfectly sweet. 

When you’re ready to bake, pull a few out, warm them to room temperature, and the skin will peel away easily. If you’re in a rush and they are frozen, set a few in a Pyrex dish and pop them in the toaster oven or microwave. You don’t need to melt the bananas, just warm them up a bit, and then simply cut off an end and the skin will peel away leaving the banana inside to be mashed up for this recipe! You can mash them with a potato masher or wooden spoon in a large mixing bowl… the sweeter the bananas, the better the muffins!

If you’ve ever made banana bread, you’ll love this quicker, banana muffin recipe. They’re the perfect way to use up old bananas and turn them into something delicious.

Ingredients for Best Banana Walnut Muffin Recipe

8 Tablespoons (4 oz.) unsalted butter, softened (or use melted butter or vegetable oil for an even moister texture)
1 cup sugar (feel free to substitute with brown sugar for even more sweet flavor)
1 large egg at room temperature
1 cup mashed ripened bananas (about 3 overripe bananas)
1 tsp nutmeg
1 tsp vanilla extract
1 tsp baking soda, dissolved in 1 tablespoon cold water
1/2 tsp salt
1 1/2 cups all purpose flour (or substitute whole wheat flour for heartier texture)
1/2 cup chopped walnuts

Optional: ¼ cup Greek yogurt or sour cream for extra moist crumbs
Optional mix-ins: chocolate chips or a drizzle of pure maple syrup for added sweetness

Step-By-Step Instructions for Banana Walnut Muffin Recipe

1. Prep your pan: Preheat your oven to 400°F. Line a muffin tray with muffin liners or muffin cups, and lightly spray with non-stick spray.

2. Cream the butter and sugar: In a large bowl or stand mixer, beat the butter and sugar together on medium speed until creamy.

3. Add the wet ingredients: Beat in the egg, mashed bananas, and vanilla extract until smooth. Stir in the baking soda-water mixture and a small spoon of Greek yogurt or sour cream for extra moisture.

4. Combine dry ingredients: In a separate bowl, whisk together the flour, nutmeg, and salt.

5. Mix it all together: Gradually combine the dry ingredients with the banana mixture, stirring gently until just combined. Don’t overmix, or you’ll end up with dry muffins.

6. Add the walnuts: Fold in the chopped walnuts (and chocolate chips if using). The batter should be thick and slightly sticky.

7. Fill and bake: Use an ice cream scoop to divide the batter evenly among the prepared muffin tin. Fill each cup about ¾ full and sprinkle a little turbinado sugar on the top of each muffin for that bakery-style crunch.

8. Bake: Bake in a preheated oven at 400°F for 12–15 minutes, or until golden brown and a toothpick inserted in the center comes out with moist crumbs (not wet batter).

9. Cool: Let the muffins cool on a wire rack for 10 minutes before serving.

Helpful Tips for Moist & Fluffy Muffins

• Use overripe bananas. The darker the peel, the sweeter the flavor.

• Always mix wet and dry ingredients separately before combining.

• Don’t overmix the muffin batter. That’s an important step to keep muffins soft.

• Add a spoonful of Greek yogurt or sour cream for a tender crumb.

• For tall muffin tops, bake at a high temperature (400°F) for the first few minutes, then lower to 375°F if they’re browning too quickly.

• Store in an airtight container at room temperature for up to 3 days, or wrap in plastic wrap and freeze in a zip-top freezer bag for later.

Variations to Try Next Time

• Banana Chocolate Chip Muffins: Add ½ cup chocolate chips for an indulgent twist.

• Whole Wheat Banana Muffins: Use half whole wheat flour for a nutty flavor.

• Coconut Oil Muffins: Replace butter with coconut oil for a tropical aroma.

• Mini Muffins: Make bite-sized muffins using this pan. Reduce bake time by 3–4 minutes.

• Banana Walnut Muffin Cake: Pour the banana mixture into a loaf pan for a simple banana bread variation.

Storing & Reheating

These muffins taste even better the next day! Store leftovers in an airtight container lined with paper towels to keep them soft. For the best flavor, warm them in a toaster oven for a few minutes and top with butter or even a scoop of banana ice cream for an afternoon snack.
