## Chunky Monkey Blondies Ingredients
For the Batter
- Unsalted Butter – Provides moisture and richness; can be substituted with coconut oil for a dairy-free option.
- Brown Sugar – Adds sweetness and a hint of caramel; light or dark brown sugar works well, but white sugar alters flavor.
- Large Egg – Serves as a binding agent for structure; for a vegan option, use 1/4 cup applesauce or a flax egg (1 tbsp flaxseed + 3 tbsp water).
- Vanilla Extract – Enhances overall flavor; pure vanilla offers a higher quality taste, while imitation is budget-friendly.
- Ripe Bananas – Provides natural sweetness and moisture; overripe bananas are preferred, or use thawed frozen bananas.
- Peanut Butter (Creamy or Chunky) – Adds flavor and texture; can be swapped with almond or sunflower butter.
- Semi-Sweet Chocolate Chips or Chunks – Brings rich chocolatey goodness; dark chocolate can give a stronger flavor.
- Reese’s Peanut Butter Cups – A delightful treat within the blondies; substitute with chopped chocolate or other candies if needed.
- Salt – Enhances flavor; use sea salt or kosher salt, and omit if using salted butter.
- Baking Soda – Acts as a leavening agent; critical for achieving the right rise.
- All-Purpose Flour or Gluten-Free Flour – Provides structure; swap in gluten-free flour blend for a gluten-free option or consider almond flour for texture variation.
These Chunky Monkey Blondies are not just dessert bars; they’re an experience, waiting to delight taste buds and warm hearts.
Step‑by‑Step Instructions for Chunky Monkey Blondies
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C) and line a 9×9-inch baking dish with parchment paper or aluminum foil. Lightly spray the lining with non-stick cooking spray to ensure your Chunky Monkey Blondies come out easily. This preparation step is crucial for achieving that perfect fudgy texture without sticking.
Step 2: Mix the Base
In a large mixing bowl, whisk together the melted unsalted butter and brown sugar until well combined and glossy, about 1-2 minutes. The mixture should be smooth and homogenous, creating a delightful foundation for your blondies. This step embeds that caramel sweetness right into your batter, setting the stage for a luscious treat.
Step 3: Add Wet Ingredients
Next, mix in the large egg, vanilla extract, creamy peanut butter, and mashed ripe bananas. Stir until everything is smooth and seamlessly blended, taking about 1-3 minutes. The vibrant flavors meld together beautifully, allowing the peanut butter and bananas to compliment each other, which is essential for the luscious taste of the Chunky Monkey Blondies.
Step 4: Combine Dry Ingredients
Add the salt, baking soda, and flour into your mixture, stirring gently until just combined. Be sure not to overmix, as this could lead to a denser texture than desired. The batter will begin to thicken, and small streaks of flour should still be visible, ensuring an airy yet fudgy interior once baked.
Step 5: Fold in Chunky Goodness
Carefully fold in the semi-sweet chocolate chunks and diced Reese’s Peanut Butter Cups into the batter until evenly distributed. This step adds delightful bursts of chocolate and peanut butter that enrich the flavor of your blondies. The chunky mix-ins are what make these blondies truly irresistible and extra fun!
Step 6: Spread into Baking Dish
Transfer the blondie batter into your prepared baking dish, using a spatula to spread it evenly to the edges. It’s important to ensure the batter is level so that it bakes evenly and develops that beautifully golden crust. Feel free to tap the dish lightly on the counter to settle the batter.
Step 7: Optional Chocolate Topping
If you’d like to elevate your Chunky Monkey Blondies even further, sprinkle any extra chocolate chips on top before baking. This additional layer of chocolate will melt beautifully, creating a rich chocolatey finish that is simply delightful. It’s just an extra touch that makes these bars even more indulgent.
Step 8: Bake to Perfection
Place the baking dish in the preheated oven and bake for 25-35 minutes, or until the edges turn golden brown and the top looks set. Keep an eye on the blondies towards the end; they should be slightly soft in the center but not wet. Avoid overbaking to maintain that fudgy, chewy texture we all love.
Step 9: Cool and Serve
Once baked, remove the blondies from the oven and let them cool in the pan for about 10-15 minutes. Then, lift them out using the parchment paper and allow them to cool completely on a wire rack. Cut into squares, and your Chunky Monkey Blondies are ready to serve, perfect for any occasion!
