Ingredients You’ll Need for This Peanut Butter Cookie Dough Bars

this RECIPE

The key to these bars lies in selecting the right ingredients—simple, quality staples that come together effortlessly. Growing up, my mum always insisted on real butter and fresh vanilla extract, and I’ve carried that preference with me. When choosing peanut butter, I go for the natural kind with no added sugar or oils to keep the flavor pure. Feel free to swap out some of the flour for oat flour if you want a bit more chewiness or go for dark chocolate chips for a richer kick.

• 1 cup natural creamy peanut butter
• 1/2 cup unsalted butter, softened
• 3/4 cup brown sugar, packed
• 1/4 cup granulated sugar
• 1 teaspoon vanilla extract
• 2 cups all-purpose flour (or substitute 1/2 cup with oat flour)
• 1/2 teaspoon salt
• 1 cup mini chocolate chips (semi-sweet or dark)
• 2-3 tablespoons milk or dairy-free alternative (optional, to adjust texture)

Steps to Create Your Peanut Butter Cookie Dough Bars

1. Line an 8×8-inch baking pan with parchment paper, leaving a slight overhang for easy removal.
2. In a large bowl, beat together the softened butter, peanut butter, brown sugar, and granulated sugar until smooth and creamy—about 3-4 minutes. This step is crucial for that melt-in-your-mouth texture.
3. Mix in the vanilla extract until fully incorporated.
4. In a separate bowl, whisk together the flour and salt.
5. Gradually add the dry ingredients to the wet mixture, stirring gently. If the dough feels too stiff, add milk a tablespoon at a time until it reaches a thick, spreadable consistency.
6. Fold in the mini chocolate chips evenly throughout the dough.
7. Spread the cookie dough mixture evenly into the prepared pan, pressing down gently to smooth the surface.
8. Chill the pan in the refrigerator for at least 2 hours, or until firm enough to cut.
9. Use the parchment overhang to lift the bars from the pan and slice into 12 squares.
10. Serve immediately or store as directed below.

Tips for Making the Best Peanut Butter Cookie Dough Bars

Getting these bars just right is about balancing texture and flavor, and a few small tweaks can make a big difference. I’ve learned over the years, especially working in professional kitchens, that patience with chilling and ingredient quality are key. When my son insists on “cookie dough now,” these tips help me deliver something he loves without compromise.

• Use room temperature butter and peanut butter for easier mixing and smoother dough.
• Don’t rush chilling—this step helps the bars set properly and makes cutting cleaner.
• If you prefer a chunkier texture, add chopped peanuts or swap mini chips for regular-sized chocolate chunks.
• Feel free to swap sugars for coconut sugar or maple syrup, but adjust the quantity slightly to maintain texture.
• For a vegan version, use dairy-free butter and plant-based milk.

Serving Suggestions and Pairings

These bars shine in casual settings, whether it’s a quick afternoon snack or an after-dinner sweet treat. I love serving them alongside a cup of tea in the late afternoon or packing a couple in my daughter’s lunchbox—she’s convinced they’re a secret treat! They’re also wonderful for potlucks or picnics, where their sturdy texture holds up well.

• Serve with a cold glass of milk or your favorite nut milk for dipping.
• Pair with fresh berries or sliced bananas for a refreshing contrast.
• Top with a drizzle of melted chocolate or caramel sauce for extra indulgence.
• Perfect alongside a simple cup of black coffee or chai tea to balance the sweetness.

Whether it’s a busy weekday or a relaxed weekend, these bars bring a little homemade joy that always feels special.

Storage and Reheating Tips

Proper storage is essential to keep these bars fresh and chewy. I often make a batch on Sunday to last through a busy week, so knowing how to store and revive them is a lifesaver.

• Store bars in an airtight container in the refrigerator for up to 5 days.
• For longer storage, freeze bars individually wrapped in parchment and then placed in a freezer bag for up to 3 months.
• To enjoy after freezing, thaw at room temperature for 30 minutes or microwave for 15-20 seconds to soften.
• Avoid reheating in the oven, as it can dry out the texture.
