Ingredients
Makes 15 muffins.
- 3 very ripe medium bananas, mashed
- 1/2 cup granulated sugar
- 1/3 cup packed light brown sugar
- 1/2 cup unsalted butter, melted and slightly cooled
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 3/4 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 1 cup semi-sweet chocolate chips
- 3/4 cup chopped walnuts
Optional topping
- 2 tablespoons additional chocolate chips
- 2 tablespoons chopped walnuts
Ingredient Notes
Bananas: Use very ripe bananas with plenty of brown spots. They provide sweetness, moisture, and the characteristic banana flavor.
Butter: Unsalted butter gives you control over the salt in the recipe. Let it cool slightly after melting so it doesn’t scramble the eggs.
Chocolate chips: Semi-sweet chocolate chips balance the sweetness of the bananas and sugars. Milk chocolate can be used for a sweeter muffin.
Walnuts: Chop the walnuts fairly small so they distribute evenly through the batter instead of sinking to the bottom.
All-purpose flour: Measure the flour by spooning it into a dry measuring cup and leveling the top. Too much flour can make banana muffins dense and dry.
How to Bake Chunky Monkey Muffins
Prepare the Oven and Muffin Pan
Heat the oven to 375°F. Line a standard 12-cup muffin pan with paper liners, then lightly grease three additional muffin cups so the batter can make 15 muffins.
Mash the bananas in a medium bowl until mostly smooth, leaving a few small pieces for texture.
Mix the Wet Ingredients
In a large bowl, whisk the melted and slightly cooled butter with the granulated sugar and brown sugar. Add the mashed bananas, eggs, and vanilla, then whisk until the mixture is evenly combined.
The mixture should look smooth and moist, with the banana distributed throughout.
Combine the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt. This evenly distributes the leavening agents throughout the flour before they’re added to the wet mixture.
Fold the Batter Together
Add the dry ingredients to the wet mixture. Use a rubber spatula to gently fold until just combined. A few small streaks of flour are fine while you’re mixing.
Fold in the chocolate chips and chopped walnuts, reserving the optional topping if you’re using it. Stop mixing as soon as no large pockets of dry flour remain.
Fill the Muffin Cups
Divide the batter evenly among the 15 prepared muffin cups, filling each about three-quarters full. If desired, sprinkle the tops with the reserved chocolate chips and chopped walnuts.
Distributing the batter evenly helps the muffins bake at the same rate.
Bake Until the Tops Are Set
Bake at 375°F for 18–22 minutes, rotating the pan once halfway through if your oven browns unevenly.
The muffins are ready when the tops are domed and lightly golden, and a toothpick inserted into the center comes out with a few moist crumbs or melted chocolate but no wet batter.
Cool Before Serving
Let the muffins cool in the pan for about 5 minutes, then transfer them to a wire rack.
Allow them to cool for another 10–15 minutes before serving. The centers will finish setting while they cool, and the chocolate will remain soft without making the muffins difficult to handle.
Recipe Tips
- Use very ripe bananas. Bananas with plenty of brown spotting have more flavor and moisture than firm yellow bananas.
- Don’t overmix the batter. Once the flour is incorporated, stop folding. Overmixing can make muffins tougher and more dense.
- Cool the melted butter slightly. Warm butter is fine, but very hot butter can affect the eggs when they’re added.
- Fill the cups evenly. Using a cookie scoop makes it easier to divide the batter consistently so the muffins finish baking at roughly the same time.
- Watch the chocolate chips. A toothpick can come out with melted chocolate even when the muffin is fully baked, so look for the absence of wet batter rather than relying on a perfectly clean tester.
- Let them cool briefly. Freshly baked banana muffins are delicate while hot. A short rest helps the crumb set without drying them out.
Variations and Substitutions
Pecans instead of walnuts: Use an equal amount of chopped pecans for a slightly different nutty flavor.
Milk chocolate: Swap the semi-sweet chocolate chips for milk chocolate chips if you prefer a sweeter muffin.
Dark chocolate: Dark chocolate chips give the muffins a deeper chocolate flavor and reduce the overall sweetness.
Nut-free: Leave out the walnuts. The muffins will still have plenty of texture from the chocolate chips.
Cinnamon banana muffins: Add 1 teaspoon ground cinnamon to the dry ingredients for a warmer spice profile.
Extra banana flavor: For an especially banana-forward muffin, use very ripe bananas and mash them by hand rather than pureeing them completely smooth.
What to Serve With Chunky Monkey Muffins
These muffins work well with simple breakfast additions:
- Scrambled or fried eggs for a more substantial breakfast
- Greek yogurt and fresh berries
- A bowl of seasonal fruit
- Peanut butter or almond butter for spreading
- Coffee, tea, or a glass of milk
Storage and Reheating
Refrigerator
Store completely cooled muffins in an airtight container for up to 4 days. Refrigeration can make muffins slightly firmer, so bring them toward room temperature before serving if preferred.
Freezer
Chunky Monkey Muffins freeze well. Wrap individual cooled muffins in plastic wrap or place them in freezer-safe bags or containers, removing as much excess air as practical.
Freeze for up to 3 months for the best texture. Thaw individual muffins at room temperature.
Reheating
For a warm muffin, microwave one at 50–70% power for about 15–25 seconds. Add a few seconds if needed, but avoid overheating because the banana crumb can become chewy.
