Ingredients
For 12 standard muffins, you’ll need:
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 1/2 teaspoon ground cinnamon
- 3 medium very ripe bananas, mashed
- 1/2 cup granulated sugar
- 1/4 cup packed light brown sugar
- 1/2 cup unsalted butter, melted and slightly cooled
- 2 large eggs
- 1 teaspoon vanilla extract
- 3/4 cup semi-sweet chocolate chips
- 1/2 cup chopped walnuts
Ingredient Notes
Bananas: Use very ripe bananas with plenty of brown spotting. They provide sweetness, moisture, and strong banana flavor.
Butter: Unsalted melted butter gives the muffins a tender crumb and lets you control the salt separately.
Chocolate chips: Semi-sweet chocolate chips provide a balanced chocolate flavor without making the muffins overly sweet.
Walnuts: Chopped walnuts add texture and a mild nutty flavor. Toast them first if you want a deeper flavor.
Flour: Measure all-purpose flour by spooning it into a measuring cup and leveling the top rather than packing it down.
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 or lightly grease each cup.
Set the pan aside while you prepare the batter. Starting with a fully preheated oven helps the muffins rise properly and develop lightly browned tops.
Whisk the Dry Ingredients
In a medium bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon.
Whisk for about 20–30 seconds so the leavening agents and cinnamon are evenly distributed throughout the flour.
Combine the Wet Ingredients
In a separate large bowl, mash the ripe bananas until mostly smooth, leaving a few small soft pieces for texture.
Add the granulated sugar, brown sugar, melted butter, eggs, and vanilla. Whisk until the mixture looks evenly blended and slightly creamy.
Allow the melted butter to cool slightly before combining it with the eggs.
Combine the Batter
Add the dry ingredients to the bowl of wet ingredients. Fold gently with a rubber spatula just until no large streaks of flour remain.
Do not overmix. The finished batter should be thick, soft, and slightly lumpy rather than completely smooth.
Fold in the Chocolate Chips and Walnuts
Add the chocolate chips and chopped walnuts to the batter. Fold them in gently with a spatula until they are distributed throughout.
Reserve a small handful of chocolate chips and walnuts if you want a more visible topping on the baked muffins.
Fill the Muffin Cups
Divide the batter evenly among the 12 prepared muffin cups, filling each about three-quarters full.
If desired, sprinkle a few reserved chocolate chips and walnut pieces over the tops. Keep the portions as even as possible so the muffins finish baking at approximately the same time.
Bake Until Golden and Set
Bake the muffins at 375°F for about 18–22 minutes.
The tops should be golden brown and spring back lightly when pressed. A toothpick inserted into the center should come out with a few moist crumbs or melted chocolate attached, but not wet batter.
Let the muffins cool in the pan for about 5 minutes before transferring them to a wire rack.
Recipe Tips
- Use very ripe bananas: Brown-spotted bananas provide stronger flavor and more moisture than firm yellow bananas.
- Don’t overmix: Stir only until the flour disappears. Excess mixing can make muffins dense and chewy.
- Measure flour carefully: Too much flour can produce a dry, heavy crumb.
- Keep the chocolate pieces distributed: Tossing the chips into the dry mixture before combining can help prevent them from settling heavily in one area.
- Check early: Muffins can vary slightly by oven and pan, so begin checking around the 18-minute mark.
- Cool before storing: Allow the muffins to cool completely so trapped heat doesn’t create excess moisture inside the storage container.
Why Ripe Bananas Work So Well
Very ripe bananas are particularly useful for banana muffins because their texture is soft enough to incorporate easily into the batter. As bananas ripen, their flavor becomes more pronounced and their natural sweetness increases.
For this recipe, choose bananas with plenty of brown spots rather than bananas that are mostly green or firm. If your bananas are unusually large, you may not need every bit of the third banana; aim for roughly 1 to 1 1/4 cups mashed banana.
Variations and Substitutions
Pecans instead of walnuts: Chopped pecans work well if you prefer their slightly sweeter, buttery flavor.
Milk chocolate chips: These make the muffins sweeter and give them a softer chocolate flavor.
Dark chocolate chips: Use dark chocolate chips for a more intense chocolate contrast with the bananas.
No nuts: Simply replace the walnuts with additional chocolate chips or leave the extra space empty.
Cinnamon adjustment: For a stronger warm-spice flavor, increase the cinnamon slightly to 3/4 teaspoon.
Whole-wheat option: Replace up to 1/2 cup of the all-purpose flour with whole-wheat flour. The muffins may be slightly denser.
What to Serve With Chunky Monkey Muffins
These muffins work well with simple breakfast and snack pairings:
- Hot coffee with milk or cream
- Black tea or chai tea
- A glass of cold milk
- Greek yogurt with fresh berries
- Fresh orange slices
- Scrambled eggs for a more substantial breakfast
Storage and Reheating
Refrigerator
Once completely cool, place the muffins in an airtight container lined with a paper towel. Store them in the refrigerator for up to 5 days.
Refrigeration can make the crumb a little firmer, so warming the muffins before eating improves their texture.
Freezer
These muffins freeze well. Cool them completely, then wrap individual muffins tightly in plastic wrap or place them in a freezer-safe bag or container.
Freeze for up to 3 months for the best quality. Thaw individual muffins at room temperature or overnight in the refrigerator.
Reheating
For a quick warm muffin, microwave one refrigerated muffin for about 10–15 seconds. From frozen, microwave in short intervals until warmed through.
For several muffins, place them in a 300°F oven for about 8–10 minutes after thawing.
