What You’ll Need for Peanut Butter Blondie Bars
- 1 cup (2 sticks) unsalted sweet cream butter, softened
- 1 cup creamy peanut butter
- 1 cup light brown sugar, packed
- 1 cup granulated sugar
- 2 large eggs
- 2 tsp vanilla extract
- 2 ¾ cups all-purpose flour
- 1 ½ tsp baking powder
- ½ tsp salt
- 2 Tbsp whole milk
- 2 oz premium dark chocolate, melted (optional, for topping)
How to Make Peanut Butter Blondie Bars
- Preheat your oven to 350°F. Line a 13×9 inch baking pan with parchment paper or foil lightly sprayed with non-stick spray.
- In a KitchenAid or using an electric hand mixer, cream together the softened butter and peanut butter until smooth.
- Beat in the light brown sugar and granulated sugar until the mixture is well-combined and fluffy.
- Add the eggs one at a time, beating well after each addition. Then, stir in the vanilla extract.
- In a separate bowl, whisk together the flour, baking powder, and salt.
- Gradually add the flour mixture to the peanut butter mixture on low speed, pausing occasionally to scrape down the sides of the bowl.
- Stir in the milk until the batter is fully combined.
- Spread the batter evenly into the prepared pan and bake for 25-28 minutes. The blondies are done when a toothpick inserted into the center comes out mostly clean with a few crumbs.
- Allow the blondies to cool completely in the pan. If desired, brush the top with melted dark chocolate before cutting into bars.
Creative Toppings to Elevate Your Blondies
While the optional melted dark chocolate adds a rich finish, consider other toppings to make your Peanut Butter Blondie Bars even more indulgent. Drizzle with caramel sauce or white chocolate for a sweet contrast. For a crunchy twist, sprinkle chopped peanuts or sea salt on top before the chocolate sets. These additions will take your blondies to the next level!
Perfect Pairings for Serving
These blondie bars are delicious on their own, but pairing them with a cold glass of milk or a scoop of vanilla ice cream makes them even more irresistible. For a cozy treat, serve alongside a cup of coffee or hot cocoa. They’re also great for dessert platters or as a sweet addition to brunch spreads.
How to Store and Keep Them Fresh
Store your Peanut Butter Blondie Bars in an airtight container at room temperature for up to 3 days. For longer storage, wrap them tightly in plastic wrap and freeze for up to 2 months. To enjoy, simply thaw at room temperature or warm them slightly in the microwave for a gooey treat.
Easy Recipe Variations to Try
Customize your blondies by adding chocolate chips, chopped Reese’s cups, or mini marshmallows to the batter before baking. For a nut-free version, swap the peanut butter with sunflower seed butter. You can also experiment with different flours, like whole wheat or gluten-free blends, to suit your dietary needs.
Time-Saving Tips for Busy Bakers
To streamline the process, measure all your ingredients before starting. Use a stand mixer to quickly cream the butter and peanut butter, and opt for pre-cut parchment paper to line your pan faster. If you’re short on time, skip the chocolate drizzle or use chocolate chips instead of melting chocolate for a simpler finish.
