• Salted Butter: Adds richness and moisture to the brownies while balancing the sweetness. The salt also enhances the peanut butter flavor.
• Creamy Peanut Butter: The star of the show! It gives the brownies their signature peanut butter flavor while adding a creamy texture.
• Granulated Sugar & Brown Sugar: The combination of these sugars provides the perfect sweetness and chewiness. Brown sugar adds a deeper, caramel-like flavor.
• Eggs: These bind the ingredients together, giving the brownies structure and a fudgy texture.
• Vanilla Extract: Enhances the overall flavor and adds warmth to the brownies.
• All-Purpose Flour: This gives the brownies their form and helps with the fudgy consistency.
• Baking Powder: A small amount helps the brownies rise just a little, giving them a light, yet dense texture.
• Salt: Brings out the sweetness and enhances the overall flavors.
• Peanut Butter Chips or Chocolate Chips (optional): These add pockets of melty goodness. Peanut butter chips enhance the peanut flavor, while chocolate chips create a nice contrast.

How to Make Peanut Butter Blondies

3. Add granulated sugar and brown sugar, and mix until well combined.
4. Beat in eggs and vanilla extract.

5. Add flour, baking powder, and salt to the wet mixture. Mix until just combined.

6. Gently fold in the peanut butter chips until evenly distributed throughout the batter.

7. Pour the batter into the prepared pan, spreading it out evenly.

8. Bake 35-40 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
9. Allow the brownies to cool in the pan before cutting into squares with a sharp knife.

Pro Tips and Substitutions

• For Extra Richness. Swap out the creamy for crunchy peanut butter if you love added texture.
• Want a Lighter Version? Try using a reduced-fat peanut butter, but keep in mind the texture may change slightly.
• Make it Gluten-Free. Substitute the all-purpose flour with a 1:1 gluten-free flour blend.
• Add a Swirl. For a fun twist, make peanut butter swirl brownies! Simply swirl a little bit of melted chocolate or more peanut butter on top with a butter knife before baking. Around 2-4 tablespoons works great!
• Make Frosted Blondies. Add one of these smooth and creamy frostings to the top these fudgey blondie brownies for extra layer of indulgence:
  • Chocolate Frosting:
    • Ingredients: ½ cup unsalted softened butter, ¼ cup unsweetened cocoa powder, 2 cups powdered sugar, ¼ cup milk (more if needed), 1 teaspoon vanilla extract
    • Steps: In a large bowl, cream butter with an electric hand mixer until smooth. Add cocoa powder and mix until combined. Gradually add powdered sugar, alternating with milk. Beat until the frosting reaches a smooth, spreadable consistency. Mix in vanilla and beat for an additional 1-2 minutes until light and fluffy. Spread over the cooled blondies!
  • Cream Cheese Frosting:
    • Ingredients: 8 oz softened cream cheese, ½ cup unsalted softened butter, 2 cups powdered sugar, 1 teaspoon vanilla extract
    • Steps: In a medium bowl, beat cream cheese and butter together until smooth and creamy. Gradually add powdered sugar, mixing on low speed until fully combined. Stir in the vanilla and beat for 1-2 minutes until fluffy. Spread over the cooled blondies!
