Ingredients
To make these scrumptious peanut butter blondies, gather the following ingredients:
For the Blondies
- 2/3 cup unsalted butter (170 grams)
- 3/4 cup peanut butter (about 270 grams)
- 2 cups light brown sugar (420 grams)
- 2 teaspoons vanilla
- 3 large eggs
- 2 cups all-purpose flour (250 grams)
- 1/4 teaspoon salt
- 3/4 cup Reese’s Pieces (about 140 grams)
- 3/4 cup chocolate chips (about 120 grams)
How to Make Peanut Butter Blondies
Step 1: Preheat the Oven
Preheat your oven to 350°F (180°C) degrees. This step ensures that your blondies bake evenly.
Step 2: Prepare the Baking Pan
Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides. Alternatively, lightly grease the pan if you prefer not to use parchment.
Step 3: Melt Butter and Peanut Butter
In a large, microwave-safe bowl, melt together the unsalted butter and peanut butter until almost fully melted. Stir until smooth.
Step 4: Mix in Sugar and Eggs
Whisk the light brown sugar into the melted mixture until well combined. Then add the eggs and vanilla extract. Whisk until no egg pieces are visible.
Step 5: Combine Dry Ingredients
Gently fold in the all-purpose flour and salt into the mixture using a rubber spatula. Mix until there are no visible streaks or lumps of flour.
Step 6: Add Chocolate Chips and Candy
Fold in both the Reese’s Pieces and chocolate chips gently to ensure they are evenly distributed throughout the batter.
Step 7: Pour into Prepared Pan
Spoon or pour the batter into your prepared baking pan. Spread it evenly with a spatula for uniform baking.
Step 8: Bake
Place in the preheated oven and bake for about 30 minutes. Check if done by inserting a toothpick; it should come out clean or with a few damp crumbs.
Step 9: Cool and Slice
Allow the blondies to cool in the pan. When ready to serve, lift them out using the parchment overhang or slice directly if greased. For best results, cool completely before slicing into generous squares.

Common Mistakes to Avoid
When making Peanut Butter Blondies, avoiding common pitfalls can significantly enhance your baking experience and results.
- Incorrect oven temperature: Baking at the wrong temperature can lead to undercooked or burnt blondies. Always preheat your oven to 350F (180C) for optimal results.
- Not measuring ingredients accurately: Using inaccurate measurements can affect the texture and flavor. Use a kitchen scale or proper measuring cups for precision.
- Overmixing the batter: Overmixing can make the blondies dense instead of soft and chewy. Mix just until combined for the best texture.
- Skipping parchment paper: Not lining your pan can lead to sticking and difficulty in removing the blondies. Either line with parchment or grease thoroughly.
- Not letting them cool properly: Slicing too soon can cause them to crumble. Allow the blondies to cool in the pan for at least 2 hours before cutting.
