How to Make Peanut Butter Blondies
These blondies with peanut butter come together in just 4 simple steps and use basic pantry ingredients you may already have on hand. Preheat your oven to 350°F and get ready to make a soft, chewy, peanut butter lover's dream dessert.
Step 1: Mix the wet ingredients. In a large mixing bowl, beat together the melted butter and brown sugar until combined. Add the peanut butter and mix until smooth, then blend in the eggs until fully incorporated.
Step 2: Add the dry ingredients. Mix in the baking soda and flour just until no dry streaks remain. Be careful not to overmix. Fold in the peanut butter chips.
Step 3: Prepare for baking. Spread the batter evenly into a greased or parchment-lined 9x13-inch baking dish.
Step 4: Bake and cool. Bake for 20 minutes, or until the edges are lightly golden and the center is set. Allow the blondies to cool completely before slicing and serving.
Expert Tips
- Mix for the best texture: Measure the flour carefully, use room-temperature eggs, and mix just until combined to keep the blondies soft and chewy rather than cakey.
- Bake and cool properly: Avoid overbaking and remove the blondies when the center looks just set. Let them cool before slicing for cleaner bars.
- Customize to your taste: Use creamy or crunchy peanut butter, add crushed peanuts, chocolate chips, candies, pretzels, or finish with flaky sea salt for extra flavor and texture.
- Choose the right pan and ingredients: A 9x13-inch pan creates thinner blondies, while an 8x11-inch pan makes thicker bars. Brown sugar adds moisture and richness, and peanut butter chips create an extra gooey texture.
- Keep prep simple: Line the pan with parchment paper or lightly coat it with nonstick spray for easy removal. These blondies also store and freeze well, making them perfect for making ahead.
