Ingredients

½ cup (1 stick) unsalted butter, melted
1 cup light brown sugar, packed
½ cup creamy peanut butter
2 large eggs
1 teaspoon vanilla extract
1 cup all-purpose flour
½ teaspoon baking powder
¼ teaspoon salt
½ cup chocolate chips or chopped peanuts (optional, for extra flavor)

Directions

1. Preheat and prepare. Preheat your oven to 350°F (175°C). Line an 8×8-inch or 9×9-inch baking pan with parchment paper or lightly grease it.

2. Mix wet ingredients. In a large bowl, whisk together the melted butter and brown sugar until smooth and well combined. Add the peanut butter, eggs, and vanilla extract. Mix until smooth and creamy.

3. Add dry ingredients. In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, stirring just until combined. Be careful not to overmix. Fold in chocolate chips or peanuts if using.

4. Pour and bake. Pour the batter into the prepared baking pan and spread it evenly. Bake for 25 to 30 minutes, until the edges are golden brown and a toothpick inserted in the center comes out with a few moist crumbs (not wet batter).

5. Cool and serve. Let the blondies cool completely in the pan before cutting into squares. This helps them set properly. Serve at room temperature.

Expert Tips

Don’t overmix. Overmixing can make blondies tough.
Use natural peanut butter. For the best flavor, use creamy peanut butter.
Check for doneness. Blondies should be slightly under-baked for fudgy texture.
Cool completely. Cutting too early can make them crumble.
Line the pan. Parchment paper makes for easy removal.
