Step‑by‑Step Instructions for Chunky Monkey Blondies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). As it warms up, grab a 9×9 inch baking dish and line it with parchment paper. Lightly spray the parchment with non-stick spray to ensure your Chunky Monkey Blondies release easily after baking.
Step 2: Mix the Base
In a large mixing bowl, whisk together melted unsalted butter and brown sugar until they are well combined and smooth, creating a luscious mixture. This should take about 1–2 minutes; you want a nice caramel-like consistency before moving on to the next step.
Step 3: Incorporate Wet Ingredients
Add in one egg, a splash of vanilla extract, creamy peanut butter, and mashed ripe bananas. Mix these ingredients until they form a smooth batter. Take a moment to appreciate the heavenly aroma—the bananas and peanut butter blend beautifully, creating a sweet and rich flavor base for your Chunky Monkey Blondies.
Step 4: Combine Dry Ingredients
Gradually stir in the salt, baking soda, and flour, mixing just until combined. Be careful not to overmix; you want to maintain the batter’s fudgy consistency. It should look thick and slightly lumpy, signaling that it’s time for the next step.
Step 5: Add Chocolate Goodness
Gently fold in semi-sweet chocolate chips or chunks into the batter, ensuring an even distribution throughout. The melted pockets of chocolate will provide delicious melty bites in your finished Chunky Monkey Blondies, enhancing their irresistible appeal.
Step 6: Prepare for Baking
Transfer the thick batter into your prepared baking dish, pressing it evenly into the corners. To elevate your treat, top the batter with chopped peanut butter cups for an extra indulgent touch. Make sure it’s well-distributed for a delightful surprise in every bite.
Step 7: Bake to Perfection
Place the baking dish in your preheated oven and bake for 25-35 minutes. You’ll know they’re ready when the top is golden and the edges are just starting to brown slightly. The center may look a bit soft—that’s okay! It will set as it cools, giving you those delicious fudgy blondies you crave.
Step 8: Cool and Serve
Once baked, remove the Chunky Monkey Blondies from the oven and let them cool in the dish for about 10-15 minutes. After they’ve cooled slightly, cut them into squares and savor the rich aroma before serving. These blondies are perfect for sharing with loved ones or enjoying as a sweet treat just for you!

How to Store and Freeze Chunky Monkey Blondies
Room Temperature: Store your Chunky Monkey Blondies in an airtight container at room temperature for up to 5 days. This keeps them soft and gooey.
Fridge: For extended freshness, keep the blondies in the fridge for up to a week. Place them in an airtight container to prevent them from drying out.
Freezer: Freeze the blondies for up to 3 months. Wrap each square in plastic wrap and then place them in a freezer-safe bag. Thaw overnight in the fridge before enjoying.
Reheating: To bring back the fudginess, warm individual blondies in the microwave for about 10-15 seconds. Enjoy the melted chocolate goodness!
Make Ahead Options
These Chunky Monkey Blondies are not just a delightful treat, they’re also perfect for meal prep! You can prepare the batter up to 24 hours in advance. Simply mix the wet and dry ingredients as instructed, and instead of baking, cover the bowl tightly and refrigerate. This helps the flavors meld beautifully while keeping your blondies just as delicious. When you’re ready to serve, preheat your oven and bake directly from the fridge, adding an extra few minutes to the baking time if necessary. This way, you can enjoy fresh, warm blondies even on your busiest days, saving you precious time without compromising on taste!

Expert Tips for Chunky Monkey Blondies
-
Don’t Overmix: Mixing the batter too much can lead to tough blondies. Just mix until combined for that fudgy texture you crave.
-
Perfectly Ripe Bananas: Choose bananas that are just starting to brown for maximum sweetness and moisture, which enhances the flavor of your Chunky Monkey Blondies.
