Chunky Monkey Bars
Chunky Monkey Bars are soft, chewy dessert bars packed with bananas, chocolate chips, and crunchy nuts. Think of them like banana bread transformed into a fun, snackable square sweet, moist, and full of texture. Kids love them because the flavors taste like a mix between banana cake and a chocolate-studded cookie, and grown-ups enjoy them because they feel satisfying without being too heavy. These bars are great for after-school snacks, lunchbox treats, or weekend baking adventures.

The name Chunky Monkey comes from the combination of bananas, chocolate, and nuts just like the famous ice cream flavor. These bars have that same delicious mix but in a warm, baked form. They’re simple to make, use easy ingredients, and don’t require any fancy baking skills. Even a beginner baker or a 10-year-old helper can help measure, mix, and spread the batter. Chunky Monkey Bars are a fun way to use up ripe bananas, reduce kitchen waste, and create something sweet, homemade, and family friendly.

Ingredients for Chunky Monkey Bars
Here’s everything you’ll need to make this Chunky Monkey Bars
- 2 ripe bananas, mashed
- 1/2 cup unsalted butter, melted
- 1/2 cup brown sugar
- 1/4 cup granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1 cup all purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup chocolate chips
- 1/2 cup chopped walnuts or pecans optional
How to Make Chunky Monkey Bars
Step One
First, preheat your oven to 175°C (350°F). Lightly grease an 8×8-inch baking pan or line it with parchment paper so the cookies release easily later.
Step Two
Now, in a large bowl, mash the bananas with a fork until smooth. They don’t need to be completely mushy; small pieces are fine. Then, add the melted butter, brown sugar, white sugar, eggs, and vanilla. Mix everything together with a spoon or whisk until the mixture is smooth and creamy.

Step Three
Next, in another bowl, whisk together the flour, baking soda, and salt. This helps distribute the baking soda evenly so the cookies rise properly. Slowly pour the dry ingredients into the wet banana mixture. Gently stir until everything is just combined. Try not to overmix; stop once the batter looks smooth.
Step Four
Stir in the chocolate chips and nuts if using. Make sure they are evenly distributed throughout the batter so each bite is unique. Pour the batter into the prepared baking pan and spread it evenly with a spatula.
Step Five
Now, bake for 22-28 minutes, or until the tops are golden brown and a toothpick inserted in the center comes out with some moist crumbs.

Step Sixe
Finally, let the pieces cool completely before cutting. This helps them set and allows for easier cutting into perfect squares.
