Prep & Cook Tools
- Mixing bowls: For combining ingredients.
- Whisk: To mix the wet ingredients smoothly.
- Spatula: For folding in the dry ingredients and chocolate chips.
- Baking pan: 9×13-inch pan to bake the blondies.
- Parchment paper: To line the baking pan for easy removal.
- Oven: Preheated to ensure even baking.
How to Prepare Thick and Chewy Triple Chocolate Peanut Butter Blondies

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This step is crucial for getting that perfect bake.
Step 2: Prepare the Baking Pan
Line a 9×13-inch baking pan with parchment paper, leaving some overhang on the sides for easy removal later. This will help prevent sticking.
Step 3: Mix the Wet Ingredients
In a large mixing bowl, combine the melted butter and creamy peanut butter. Whisk them together until smooth. Add the brown sugar, eggs, vanilla extract, and salt, whisking until everything is well combined and creamy.
Step 4: Add the Dry Ingredients
Gradually add the all-purpose flour to the wet mixture. Use a spatula to fold the flour in gently until just combined. Be careful not to overmix!
Step 5: Fold in the Chocolate Chips
Add the dark chocolate chips, milk chocolate chips, and white chocolate chips to the batter. Gently fold them in until evenly distributed.
Step 6: Pour into the Pan
Spread the batter evenly into the prepared baking pan. Use the spatula to smooth the top.
Step 7: Bake
Place the pan in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Be careful not to overbake, as you want the blondies to remain chewy.
Step 8: Cool and Cut
Once baked, remove the pan from the oven and let it cool in the pan for about 10 minutes. Then, use the parchment paper to lift the blondies out of the pan and transfer them to a wire rack to cool completely before cutting into squares.
Fresh Seasonal Changes

- Fall: Add chopped apples or pumpkin puree for a seasonal twist.
- Winter: Incorporate peppermint extract and crushed candy canes for a festive flair.
- Spring: Use white chocolate chips with a hint of lemon zest for a refreshing taste.
- Summer: Fold in some chopped nuts, such as pecans or walnuts, for added crunch.
Problems & Prevention
- Blondies Too Gooey: Ensure you bake them long enough; check them at the minimum time to prevent underbaking.
- Blondies Too Dry: Avoid overmixing the batter and check final baking time closely.
- Sticking to the Pan: Always line your pan with parchment paper and grease it lightly for easy removal.
- Uneven Baking: Rotate the pan halfway through the baking time for even results.
