Ingredients
You’ll need simple baking ingredients plus ripe bananas, chocolate chips, and walnuts.
Ingredient Notes
Ripe bananas: Use bananas with plenty of brown spots. They’re softer, sweeter, and easier to mash, making them ideal for moist banana muffins.
All-purpose flour: Standard all-purpose flour gives these muffins a tender but sturdy crumb.
Butter: Unsalted butter lets you control the amount of salt in the recipe. Melt it and let it cool slightly before adding it to the wet ingredients.
Chocolate chips: Semi-sweet chocolate chips balance the sweetness of the banana and sugar. Milk chocolate can be used for a sweeter muffin.
Walnuts: Chopped walnuts provide the characteristic crunch of a chunky monkey-style muffin. Pecans are a workable alternative.

For the Muffins
How to Bake Chunky Monkey Muffins
1. Prepare the Oven and Muffin Pan
Preheat the oven to 375°F. Line a standard 12-cup muffin pan with paper liners or lightly grease the cups.
Let the oven fully preheat before the batter goes in. A properly heated oven helps the muffins rise quickly and develop rounded tops.
2. Mix the Dry Ingredients
In a medium bowl, whisk together the flour, granulated sugar, brown sugar, baking soda, baking powder, and salt.
Whisk just long enough to distribute the leaveners and salt evenly. This helps prevent pockets of baking soda or baking powder in the finished muffins.
3. Combine the Wet Ingredients
In a separate large bowl, mash the ripe bananas until mostly smooth with a few small pieces remaining. Whisk in the eggs, melted butter, and vanilla extract until evenly combined.
The butter should be warm or room temperature rather than piping hot so it doesn’t cook the eggs when they are combined.
4. Make the Batter
Add the dry ingredients to the banana mixture. Fold gently with a spatula until you no longer see large streaks of flour.
Fold in the chocolate chips and chopped walnuts, reserving a small amount of each for the tops if desired. Don’t overmix—the batter should look thick and slightly lumpy.
5. Fill the Muffin Cups
Divide the batter evenly among the 12 prepared muffin cups, filling each about three-quarters full. Sprinkle the reserved chocolate chips and walnuts over the tops if using.
For more even muffins, use a cookie scoop or large spoon to portion the batter rather than estimating each cup individually.
6. Bake Until Golden and Set
Bake at 375°F for 18–22 minutes, or until the tops are golden and a toothpick inserted into the center comes out with a few moist crumbs rather than wet batter.
Avoid overbaking. The muffins will continue to firm slightly as they cool, while pulling them from the oven when they’re just done helps preserve their moist banana crumb.
7. Cool Before Serving
Let the muffins cool in the pan for about 5 minutes, then transfer them to a wire rack to cool further.
They can be enjoyed warm while the chocolate chips are still soft, or cooled completely for easier storage.
Recipe Tips
- Use very ripe bananas: Bananas with plenty of brown spotting provide stronger banana flavor and plenty of moisture.
- Measure flour carefully: Spoon flour into a measuring cup and level it rather than packing it down. Too much flour can make muffins dense and dry.
- Don’t overmix: Once the flour is added, fold only until the dry ingredients are incorporated. A few small lumps are fine.
- Don’t overbake: Start checking around 18 minutes. A toothpick should show moist crumbs, not raw batter.
- Keep the chocolate chips distributed: Tossing the chips through the batter rather than leaving them all near the surface helps spread the chocolate throughout the muffins.
- Toast the walnuts if you want deeper flavor: Toast chopped walnuts in a dry skillet over medium-low heat for a few minutes, then cool them completely before adding them to the batter.
Variations and Substitutions
Chocolate: Use milk chocolate chips for a sweeter muffin or dark chocolate chips for a more intense chocolate flavor.
Nuts: Pecans can replace walnuts in an equal amount. If you need nut-free muffins, simply leave the walnuts out.
Butter: Melted coconut oil can be used instead of melted butter, although it will give the muffins a slightly different flavor and texture.
Spices: Add 1/2 teaspoon of ground cinnamon for a warmer banana-bread flavor.
Mini muffins: Use a mini muffin pan and begin checking for doneness much earlier, since the smaller muffins bake faster.
What to Serve With Chunky Monkey Muffins
These muffins work especially well with:
- Scrambled or hard-boiled eggs for a more substantial breakfast
- Greek yogurt and fresh berries
- A cup of coffee or tea
- A glass of cold milk
- Fresh fruit for a simple breakfast plate
Storage and Reheating
Refrigerator
Once completely cooled, store the muffins in an airtight container. They can be refrigerated for up to 5 days, although refrigeration may make the crumb slightly firmer.
Freezer
For longer storage, freeze cooled muffins in a freezer-safe bag or airtight container for up to 3 months. Wrap individual muffins first if you want to remove them one at a time.
Thaw at room temperature or overnight in the refrigerator.
Reheating
For a warm muffin, microwave one at a time for about 10–15 seconds. Check the temperature and add a few more seconds if needed.
