Ingredients
- 1/2 cup (115 grams) unsalted butter, melted (adds moisture and richness)
- 1 cup (200 grams) light or dark brown sugar (provides sweetness and a chewy texture)
- 1/2 cup (125 grams) creamy peanut butter (adds richness and creamy texture)
- 1 large egg, room temperature (binds ingredients and adds moisture)
- 1 teaspoon pure vanilla extract (enhances overall flavor)
- 1 and 1/2 cups (190 grams) all-purpose flour, spooned & leveled (provides structure)

How to Make Peanut Butter Blondies with Chocolate Chips
Step 1. Preheat your oven to 350°F (177°C). While the oven heats up, prepare your baking pan. Line it with aluminum foil, ensuring you have some overhanging foil on the edges. This will help you lift the blondies out easily later on. Setting this up early saves time and effort when the batter is ready.
Step 2. In a large mixing bowl, add the melted unsalted butter and the brown sugar. Whisk them together until the mixture is smooth and well blended. The sugar will start to dissolve slightly, creating a glossy texture. This step is important for ensuring the sugar evenly incorporates into the batter.
Step 3. Next, mix in the creamy peanut butter, room temperature egg, and vanilla extract. Continue whisking until these ingredients are fully combined. The batter will take on a slightly thicker consistency, integrating the rich flavors of the peanut butter and vanilla seamlessly into the mixture.
Step 4. Once combined, add the all-purpose flour and salt to the bowl. Using a spatula, gently mix them into the wet ingredients until just combined. Be careful not to overmix, as this can lead to a denser texture. The batter should still look a bit lumpy but well incorporated.
Step 5. Stir in the semi-sweet chocolate chips until they’re evenly distributed in the batter. These will add pockets of chocolatey goodness throughout your blondies. Ensure not to overmix here; a few gentle folds will suffice.
Step 6. Scoop the blondie batter into the prepared baking pan. Use your spatula to spread the batter into an even layer, smoothing the top as best as you can. If desired, sprinkle a few more chocolate chips on top and gently press them into the batter. This step adds a nice visual appeal and extra chocolate flavor on top.
Step 7. Place the baking pan in the preheated oven and bake at 350°F for 30-35 minutes. You’ll want to watch for the surface of the blondies to become set and slightly golden. A toothpick inserted in the center should come out with a few moist crumbs. This indicates they are baked just right.
Step 8. Once they’re done, remove the blondies from the oven. Allow them to cool in the pan for at least 1 hour before lifting them out using the overhanging foil. Cutting them while they are still warm may result in crumbling, so patience is key here.

Pro Tips for Best Results
- Use room temperature ingredients: This helps create a smoother batter and ensures even baking.
- Measure flour correctly: Use the spoon-and-level method for accurate measurements, preventing overly dense blondies.
- Cool completely before cutting: Allow the blondies to cool fully; this helps them firm up and makes cutting easier.
- Try different chocolate chips: Experiment with dark chocolate or peanut butter chips for variety in flavor.
- Store properly: Ensure blondies are stored in an airtight container to maintain freshness.
Common Mistakes to Avoid
- Not measuring ingredients correctly: Using more flour can lead to dryer blondies. Always spoon flour into your measuring cup and level it off with a knife.
- Overmixing the batter: This can result in dense blondies. Mix until combined, and then stop to avoid incorporating too much air.
- Using cold eggs: Cold eggs can cause the batter to be lumpy. Ensure eggs are at room temperature for a smoother consistency.
- Not checking for doneness: Baking time can vary. Always check with a toothpick and look for moist crumbs rather than a clean pick for ideal texture.
- Cutting too soon: If you cut the blondies while warm, they may crumble. Allow them to cool completely for cleaner bars.
- Pans without foil: Not lining your pan can lead to stuck blondies, making removal challenging. Use the foil for easy lifting.
Variations & Substitutions
Consider adding chopped nuts like walnuts or pecans for added texture. Swapping in butterscotch chips alongside or instead of chocolate chips can provide a different sweetness. For a more pronounced peanut flavor, try using crunchy peanut butter in place of creamy.
Storage & Reheating
Store leftover blondies at room temperature in an airtight container for up to three days. For longer storage, you can refrigerate them but note that they may dry out slightly. If you’d like to freeze them, wrap each blondie individually in plastic wrap and place them in a freezer bag. They can be thawed in the fridge overnight. Reheat in the microwave for 10-20 seconds to regain a soft texture.
