How to Make Peanut Butter Cookie Bars

Step 1: Preheat and Prepare Pan

Start by heating your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving extra edges hanging over so it’s easy to lift the bars out later. Lightly grease the paper to prevent sticking.

Step 2: Combine Wet Ingredients

In a large bowl, mix the creamy peanut butter, brown sugar, and granulated sugar until smooth and creamy. Then, beat in the egg and vanilla extract until fully combined and slightly fluffy.

Step 3: Mix Dry Ingredients

In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. This ensures even distribution of the leavening and salt throughout your bars.

Step 4: Blend Wet and Dry Together

Slowly add the dry ingredients to the wet peanut butter mixture, folding gently until a thick, uniform dough forms. Be careful not to overmix to maintain a tender texture.

Step 5: Transfer and Bake

Spread the dough evenly into your prepared pan, smoothing the top with a spatula. Bake for 20 to 25 minutes or until the edges turn golden and a toothpick inserted near the center comes out almost clean with a few moist crumbs.

Step 6: Cool and Cut

Let the bars cool completely in the pan on a wire rack before lifting them out. Cut into squares or rectangles, and enjoy!

Pro Tips for Making Peanut Butter Cookie Bars

• Use Room Temperature Ingredients: Softened peanut butter and eggs blend easier for a uniform batter.
• Don’t Overbake: Remove the bars when they’re just set to keep them chewy rather than dry.
• Customize Texture: Swap creamy peanut butter for chunky to add a delightful crunch.
• Chill Dough for Thicker Bars: Refrigerate the batter for 30 minutes before baking to prevent spreading.
• Line Your Pan Properly: Parchment paper with overhang makes removing and slicing the bars much easier and cleaner.

How to Serve Peanut Butter Cookie Bars

Garnishes

For a little extra flair, sprinkle chopped peanuts or a light dusting of powdered sugar on top. Drizzling melted chocolate or peanut butter glaze adds a touch of elegance perfect for gifting or special occasions.

Side Dishes

Serve your Peanut Butter Cookie Bars alongside a cold glass of milk or a scoop of vanilla ice cream for a classic treat. A cup of hot coffee or chai tea also pairs beautifully, making snack time feel like a cozy indulgence.

Creative Ways to Present

Cut the bars into bite-sized squares and thread toothpicks through them for party snacks. You can also sandwich them with marshmallow fluff or spread Nutella between two bars for an extra delicious dessert sandwich.

Make Ahead and Storage

Storing Leftovers

Store leftover Peanut Butter Cookie Bars in an airtight container at room temperature for up to 4 days. Keeping them sealed will help retain their chewiness without drying out.

Freezing

Wrap individual bars tightly in plastic wrap and place them in a freezer-safe bag or container. Freeze for up to 3 months and thaw at room temperature before serving for a quick, ready-to-eat treat.

Reheating

To bring back that fresh-baked warmth, microwave a bar for 10 to 15 seconds or warm it in the oven at 300°F (150°C) for about 5 minutes. This refreshes the softness and intensifies the peanut butter aroma.
