Step‑by‑Step Instructions for Chunky Monkey Brownies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms, grab a 9×13 glass baking dish and generously spray it with cooking spray to ensure your brownies won’t stick. This initial step sets the stage for perfect Chunky Monkey Brownies that are moist and fudgy.
Step 2: Mix the Wet Ingredients
In a medium bowl, combine softened unsalted butter, eggs, both brown and granulated sugars, salt, and vanilla extract. Using an electric mixer, beat these ingredients together on medium speed until the mixture is smooth and creamy, which should take about 2-3 minutes. This base ensures rich flavor and a delightful texture.
Step 3: Add Flour and Banana
Next, gently fold in the all-purpose flour and the mashed ripe banana. Mix until just combined; be careful not to overmix! The bananas will add natural sweetness and moisture, ensuring your brownies are soft and luscious. This step is crucial for achieving that distinctive Chunky Monkey flavor.
Step 4: Fold in Chocolate Chips
Once the batter is combined, it’s time to fold in the semi-sweet chocolate chips. Use a spatula to gently incorporate them, ensuring an even distribution throughout the batter. These little bursts of chocolate will enhance the fudgy goodness of your Chunky Monkey Brownies and make them incredibly indulgent.
Step 5: Pour into Baking Dish
Pour the brownie batter into your prepared baking dish, using a spatula to spread it out evenly. This ensures that every corner of your pan is filled with that delicious batter. You’ll want it to be smooth on top to encourage even baking, which is essential for that perfectly fudgy texture.
Step 6: Add Topping
For an extra touch of decadence, sprinkle some additional chocolate chips on top of the batter. This optional step will create a beautiful, melty layer on your brownies as they bake, enticing everyone with their rich appearance.
Step 7: Bake the Brownies
Place the baking dish in the preheated oven and bake for 35 to 40 minutes. Keep an eye on them; the edges should be set, and a toothpick inserted in the center should come out with a few moist crumbs, indicating a fudgy consistency. Do not overbake for that perfect chewy texture.
Step 8: Cool and Serve
Once baked, remove the brownies from the oven and let them cool in the pan for about 10-15 minutes. This cooling time allows the brownies to set properly. Afterward, cut them into squares and serve—these Chunky Monkey Brownies will be a hit with your family and friends!

Make Ahead Options
These Chunky Monkey Brownies are perfect for meal prep enthusiasts! You can mix up the batter and refrigerate it up to 24 hours in advance, allowing the flavors to meld beautifully. To prepare ahead, simply follow the first five steps of the recipe and store the unbaked batter in an airtight container. When you’re ready to indulge, pour the batter into your prepared baking dish, add the chocolate chips on top, and bake as directed. To ensure they stay moist and fudgy, remember to cool the brownies completely before storing them in an airtight container at room temperature for up to 5 days. You’ll enjoy the time-saving benefits of having a delicious treat ready whenever you need it!

Chunky Monkey Brownies Recipe FAQs

What is the best way to store Chunky Monkey Brownies?
To keep your brownies fresh, store them in an airtight container at room temperature for up to 5 days. This will maintain their moist texture. If you want to keep them longer, refrigeration is an option for up to a week, but they may lose a bit of their softness.

What should I do if my brownies turn out too dry?
If your Chunky Monkey Brownies are dry, it’s likely they were overbaked. Always check for doneness around the 35-minute mark, as ovens can vary. Aim for edges that are set but a toothpick inserted in the center should come out with a few moist crumbs for that perfect fudgy texture.
