3-Ingredient Peanut Butter Blondies


Transfer the batter to the prepared pan.

Use a spatula to press it into an even layer, spreading it all the way to the corners. An even thickness helps the blondies bake consistently.

Step 4: Bake

Bake for 18–22 minutes, or until the edges look set and lightly golden.

The center may still feel a little soft when the pan comes out of the oven. That’s fine—the blondies will continue to firm up as they cool. Avoid leaving them in the oven until the entire surface feels hard, since that can lead to a dry result.

Step 5: Cool and Slice

Let the blondies cool completely in the pan.

Once they’re set, use the parchment paper to lift them out. Cut into squares with a sharp knife, wiping the blade between cuts for cleaner edges.

Tips for Soft and Chewy Blondies

Use thick peanut butter. A creamy peanut butter with a consistent texture makes the batter easier to mix and spread.

Pack the brown sugar. Press it firmly into the measuring cup so you use the intended amount.

Don’t overbake. The edges should be set, but the middle can remain slightly soft. Overbaking may make the bars dry or crumbly.

Allow enough cooling time. The blondies are delicate while warm. Cooling helps them hold their shape when sliced.

Spread the batter evenly. If one side is much thicker than the other, it may bake unevenly.

Easy Ways to Customize the Recipe

The three-ingredient version is delicious on its own, but you can add a little variety when you feel like experimenting. These additions will make it a recipe with more than three ingredients.

  • Chocolate chip blondies: Fold in about ¼ cup chocolate chips.

  • Crunchy peanut butter blondies: Use crunchy peanut butter for extra texture.

  • Chocolate-topped bars: Sprinkle chocolate chips over the batter before baking.

  • A hint of vanilla: Add ½ teaspoon vanilla extract.

  • A touch of salt: Add a small pinch if your peanut butter is unsalted.

  • Peanut butter and jelly: Serve a cooled blondie with a little fruit jam.

How to Serve Peanut Butter Blondies

These blondies are delicious at room temperature, when their texture is soft and chewy. For a more indulgent dessert, serve a square slightly warm with a scoop of vanilla ice cream.

They also pair nicely with:

  • A cold glass of milk

  • Coffee or tea

  • Fresh strawberries or banana slices

  • Brownies or cookies on a dessert platter

Because they’re rich, you can cut them into smaller squares when serving a crowd.

How to Store Peanut Butter Blondies

Let the blondies cool completely before storing them.

  • At room temperature: Store in an airtight container for up to 3 days.

  • In the refrigerator: Keep in an airtight container for up to 1 week. Chilling may make them firmer.

  • In the freezer: Wrap individual squares and place them in a freezer-safe container for up to 2 months.

Thaw frozen blondies at room temperature. If you like them slightly warm, heat a square briefly in the microwave.

Frequently Asked Questions

Can I use crunchy peanut butter?

Yes. Crunchy peanut butter works well and adds bits of peanut throughout the blondies. The finished texture will be less smooth than when using creamy peanut butter.

Can I use natural peanut butter?

You can, but results may vary. Natural peanut butter can be thinner or have separated oil, which may affect the batter. Stir it thoroughly before measuring and choose a thick consistency when possible.

Why did my blondies turn out crumbly?

Overbaking is one possible reason. Make sure the ingredients are fully combined, and remove the pan when the edges are set and the center is no longer wet. Let the blondies cool completely before slicing.

How can I tell when they’re done?

Look for set edges and a center that no longer appears wet. The middle may still be soft when warm, so cooling is an important part of getting the final texture right.

Can I double the recipe?

Yes. You can double the ingredients and bake the batter in a larger pan. Since the thickness will affect the baking time, begin checking for doneness near the end of the expected baking range rather than relying on the original timing.
