- All-purpose flour (1 ½ cups): The backbone that holds everything together with the right chewiness.

How to Make Peanut Butter Chocolate Chip Cookie Bars Recipe
Step 1: Prepare Your Pan and Oven
Start by preheating your oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper to ensure easy removal and cleanup, or lightly grease it if you prefer. This prep step sets the stage for perfectly baked bars.
Step 2: Cream Together the Wet Ingredients
In a large bowl, use a hand or stand mixer to blend peanut butter, softened butter, and brown sugar until smooth and creamy. This combination creates the rich base of your bars. Next, add the vanilla extract and eggs one at a time, mixing thoroughly after each addition to make sure the batter is fully combined and silky.
Step 3: Combine the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. This dry mixture ensures your bars will have the perfect structure and taste. Gradually add the dry ingredients to the wet mixture, mixing just until combined so your bars come out tender and not overworked.
Step 4: Fold in the Chocolate Chips
Gently fold the chocolate chips into the batter, distributing them evenly. This step guarantees every bite has a delightful burst of chocolate without overwhelming the peanut butter flavor.
Step 5: Bake to Perfection
Spread the dough evenly into the prepared baking dish. Bake for 25 to 30 minutes, or until the edges turn golden and a toothpick inserted in the center comes out clean. The aroma while baking will be irresistible!
Step 6: Cool and Cut
Let the bars cool in the pan for about 10 minutes—this helps them set and makes cutting clean squares easier. Slice into 12 bars and get ready to enjoy.
How to Serve Peanut Butter Chocolate Chip Cookie Bars Recipe

Garnishes
For an extra touch, sprinkle a pinch of sea salt flakes over the bars right after baking to amplify the peanut butter and chocolate notes. You can also drizzle melted peanut butter or chocolate on top for visual appeal and added flavor depth.
Side Dishes
These bars pair wonderfully with a cold glass of milk or even a scoop of vanilla ice cream for a decadent dessert experience. For a brunch twist, serve alongside fresh fruit or yogurt to balance the sweetness.
Creative Ways to Present
Try stacking these bars on a festive platter with nuts and chocolate chunks scattered around to make an inviting centerpiece. Wrapping individual bars in parchment paper tied with twine is perfect for gifting or party favors.
Make Ahead and Storage
Storing Leftovers
Store leftover cookie bars in an airtight container at room temperature for up to 4 days. Keeping them sealed maintains their soft and chewy texture while preventing them from drying out.
Freezing
You can freeze these bars to enjoy later by wrapping them individually in plastic wrap and placing them in a freezer bag. They’ll stay fresh for up to 3 months. Thaw at room temperature when ready to eat.
Reheating
To bring back that freshly baked warmth, microwave a bar for about 15 seconds or warm it in a low oven for 5 minutes. The chocolate will soften beautifully, reviving that delightful gooeyness.
FAQs
Can I use crunchy peanut butter in this recipe?
Absolutely! Crunchy peanut butter adds a nice bit of texture to the bars, making each bite even more interesting without changing the overall flavor.
Are these bars gluten-free?
This recipe uses all-purpose flour, so it is not gluten-free by default. However, you can substitute with a gluten-free flour blend to accommodate dietary needs, just be mindful of potential texture changes.
Can I substitute the chocolate chips with another type of mix-in?
Definitely! Feel free to swap chocolate chips for white chocolate, butterscotch, or even chopped nuts to customize the bars to your liking.
What if I prefer less sweet bars?
Reducing the brown sugar slightly can help, but remember that sugar also affects texture and moisture. You might want to experiment with small adjustments to find your perfect balance.
Can I make these bars vegan?
To make a vegan version, use a plant-based butter substitute, flax eggs instead of regular eggs, and dairy-free chocolate chips. This way, everyone can enjoy the Peanut Butter Chocolate Chip Cookie Bars Recipe!
