Ingredients for betty crocker peanut butter cookie bars
Fifteen minutes of prep, twenty-five minutes of baking perfection. These ingredients transform into nostalgic, richly nutty bars with crisp edges and gooey swirls.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Creamy Peanut Butter 🥜 | 1 cup | Natural, no added sugar |
| Granulated Sugar 🍚 | 1 cup | White or light brown |
| Packed Brown Sugar 🍚 | ½ cup | Lightly packed |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for creaming |
| Large Eggs 🥚 | 2 whole | Room temperature |
| Vanilla Extract 🌿 | 1 tsp | Pure, high-quality |
| Baking Soda 🍃 | ½ tsp | Pure, not baking powder |
| Salt 🧂 | ¼ tsp | Diamond Crystal preferred |
| Powdered Sugar 🍚 | ½ cup | For dusting |
| Chocolate Chips 🍫 | ½ cup | Semi-sweet, optional |
| Semisweet Chocolate Bars 🍫 | 4 oz | Melted for drizzle |
The peanut butter is your secret weapon here—natural, no-sugar-added gives the best flavor without overpowering. Jif or Skippy work perfectly, but if you're using a sugar-free version, add 1 tablespoon of honey to the dough. The brown sugar should be lightly packed to avoid extra moisture. For the butter, cold cubes create flaky layers, but don’t let it get too soft or the dough will spread too much. I always grab Land O’Lakes unsalted butter from the freezer section—it stays cold longer and gives that perfect texture. The flour? King Arthur or Gold Medal for the best rise and tenderness.
No creamy peanut butter? Crunchy works in a pinch, but blend it first to mimic the smooth texture. Running short on vanilla? Almond extract at half the amount adds depth, though it’ll taste different. The chocolate chips are optional, but if you skip them, add an extra 0.25 cup of peanut butter to keep the richness. For the chocolate drizzle, Ghirardelli or Lindt bars melt beautifully—just chop them into small pieces for even melting. And if you’re worried about cracks, press the dough firmly into the pan before baking, then chill it for 15 minutes before adding the peanut butter swirls.
These bars stay fresh for 5 days at room temperature or 1 week in an airtight container. For longer storage, freeze them for up to 3 months. I like to portion them into single servings before freezing—just wrap each bar tightly in plastic wrap and pop them into a freezer bag. To reheat, warm at 350°F for 5-7 minutes until the edges are crisp again. Trust me, they’re even better the second day—if they last that long!

Step-by-step instructions for Betty Crocker peanut butter cookie bars
Here's how to achieve those legendary nutty swirls and crisp edges every time—no shortcuts, just foolproof technique.
Cream Butter and Sugars to Peak Fluffiness
In a stand mixer fitted with the paddle attachment, combine the 0.75 cup unsalted butter (cold, cubed) with 1 cup granulated sugar and 0.5 cup packed brown sugar. Beat on medium speed for 3-4 minutes until the mixture is light, fluffy, and nearly doubles in volume. You're looking for a pale, ribbon-like consistency that leaves clean streaks when the paddle lifts—this incorporates air for that signature tender crumb.
I like to scrape down the sides every 30 seconds to ensure even mixing. If the butter melts too quickly, reduce the speed to low and let it re-solidify slightly before continuing. This step is non-negotiable for the perfect texture—under-creaming leads to dense bars, while over-creaming develops gluten.
Build the Cookie Base with Peanut Butter and Dry Ingredients
Add the 1 cup creamy peanut butter, 2 whole large eggs (room temperature), and 1 teaspoon vanilla extract to the butter-sugar mixture. Beat on medium speed for 1-2 minutes until fully combined and smooth. The peanut butter should be completely incorporated with no visible streaks.
In a separate bowl, whisk together the 2 cups all-purpose flour, 0.5 teaspoon baking soda, and 0.25 teaspoon salt. With the mixer on low speed, gradually add the dry ingredients to the wet mixture, mixing just until combined. Avoid overmixing—you should still see a few flour streaks. This ensures a tender texture rather than a tough one. Fold in the 0.5 cup chocolate chips by hand using a silicone spatula to distribute them evenly.
Prepare the Peanut Butter Swirl Dough
In a small bowl, combine 0.25 cup granulated sugar, 0.25 cup packed brown sugar, 0.25 cup creamy peanut butter, and 0.25 cup unsalted butter (softened). Mix until smooth and spreadable—this will be your swirl dough. Roll it into a 1-inch diameter log and wrap it in plastic wrap. Chill in the refrigerator for 30 minutes to firm up while you prepare the main dough.
Take the main dough (from Step 2) and press it into a 9x13-inch baking pan lined with parchment paper, spreading it evenly to the edges. Use a spatula to create a thin, even layer—about ¼-inch thick. This ensures even baking and those perfect pressed edges. Return the pan to the refrigerator for 15 minutes to firm up slightly before adding the swirl.
Create the Signature Swirl Pattern
Remove the chilled main dough from the refrigerator and place the chilled peanut butter log in the center. Using a butter knife, gently press the edges of the main dough toward the center, folding it over the peanut butter log to create a spiral. Press firmly but evenly to ensure the peanut butter spreads slightly—this creates those beautiful swirls when baked.
Use the back of the knife to smooth the top into an even layer. The edges should be crisp and well-defined, with the peanut butter peeking through in thin ribbons. If the dough feels too soft to handle, return it to the refrigerator for 5-10 minutes to firm up. This step is where the magic happens—take your time to create clean, even swirls for that classic Betty Crocker look.
Bake to Golden Perfection and Finish with Chocolate Drizzle
Preheat your oven to 350°F. Bake the cookie bars for 25-30 minutes, or until the edges are golden brown and the center still looks slightly soft (it will firm up as it cools). Rotate the pan halfway through baking for even cooking. You'll know they're done when the top springs back slightly when pressed gently with your finger.
Remove from the oven and let cool in the pan for 10 minutes. While still warm, melt the 4 oz semisweet chocolate bars in a microwave-safe bowl in 30-second intervals, stirring between each, until smooth. Drizzle the melted chocolate over the warm bars in an even zigzag pattern. Let the chocolate set completely before slicing into 16 bars—this ensures clean cuts and that professional finish.
For the ultimate presentation, dust the cooled bars with 0.5 cup powdered sugar using a fine-mesh sieve. Serve at room temperature for the perfect balance of crisp edges and gooey peanut butter swirls. These bars keep well in an airtight container for up to 5 days, though they rarely last that long!
Pro Tips For Making Betty Crocker Peanut Butter Cookie Bars
- MEASURE PEANUT BUTTER PRECISELY: After making these bars more times than I can count, I learned: do not eyeball the peanut butter. Use a kitchen scale for 1 cup (160g) of creamy peanut butter—packed firmly into the measuring cup. That extra ounce of oil from scooping straight from the jar makes the bars greasier and less crisp at the edges.
- CREAM BUTTER AND SUGARS FIRST: Skip the urge to toss everything into the mixer at once. Melt the butter first, then whisk in the brown and granulated sugars until it’s fully dissolved—no grainy bits. This ensures the peanut butter incorporates smoothly and the batter stays uniform. (Yes, even if you’re impatient like me.)
- BAKE UNTIL GOLDEN, NOT DONE: The recipe might say "10 minutes," but pull them out when the edges are deep golden brown, not just set. Underbaked bars taste gummy; overbaked ones turn dry. If your oven runs hot, check at 8 minutes—better to pull them slightly underdone than risk dryness.
- CHILL THE DOUGH: I used to rush straight to baking, but chilling the dough for at least 30 minutes (or up to 24 hours) makes all the difference. The peanut butter stays put, the bars hold their shape better when cutting, and the texture is chewier—not crumbly. (Pro move: cover with plastic wrap for easy cleanup.)
Creative variations of betty crocker peanut butter cookie bars
Nutty Chocolate Twist
Swap half the peanut butter for chocolate hazelnut spread like Nutella for a rich, dual-nut flavor. Use ½ cup peanut butter and ½ cup Nutella in the main dough, then add a ¼ cup Nutella log alongside the peanut butter swirl.
The result? A decadent, Nutella-peanut butter fusion with every bite. 🌟
Salted Caramel Swirl
Add a salty-sweet dimension by folding ½ cup caramel bits into the main dough and creating a ¼ cup salted caramel log> alongside the peanut butter.
I like Trader Joe’s Salted Caramel Bits for their perfect balance. The caramel melts beautifully during baking, creating pockets of gooey sweetness that contrast the nutty base.
Spiced Peanut Butter
Infuse warmth by adding ½ teaspoon cinnamon, ¼ teaspoon ginger, and a pinch of nutmeg to the peanut butter swirl dough. For extra depth, fold 1 tablespoon orange zest into the main dough.
The spices complement the peanut butter beautifully, creating a cozy, aromatic twist perfect for fall baking. 🍂
Cookie Dough Swirl
For a playful surprise, replace the peanut butter swirl with cookie dough>—either store-bought (like Ben & Jerry’s Cookie Dough Ice Cream mix) or homemade. Roll it into a log and chill as directed.
The cookie dough adds chewy pockets and a fun, unexpected texture that kids and adults love. Just be mindful of raw egg if using homemade dough.
White Chocolate Peanut Butter
Elevate the classic with a white chocolate drizzle>. After baking, melt 4 oz white chocolate chips with 1 tablespoon coconut oil for a silky finish. Drizzle over the warm bars and sprinkle with crushed pretzels for a salty contrast.
The white chocolate adds a creamy, milky note that pairs beautifully with the peanut butter’s richness.
Gluten-Free Adaptation
For a gluten-free version, replace the all-purpose flour with a 1:1 gluten-free baking flour blend> like Bob’s Red Mill. Add ½ teaspoon xanthan gum to improve texture.
The gluten-free dough spreads slightly more, so press it into a 9x13-inch pan> lined with parchment and bake for 22-25 minutes> (check at 20 minutes>). The result is just as crisp-edged and delicious!

Frequently asked questions
Why do my peanut butter bars crack?
Cracking usually happens when the dough spreads unevenly or the oven isn't preheated properly. Always press the dough firmly into the pan and chill it for 15 minutes before adding the peanut butter swirl. Preheat your oven to 350°F for 10 minutes to ensure even baking. A slightly thicker dough layer (¼-inch) also helps prevent cracks.
Can I use crunchy peanut butter instead of creamy?
Yes, but blend crunchy peanut butter first to achieve a smoother texture. For best results, use natural creamy peanut butter> with no added sugar. If you must use crunchy, pulse it in a food processor until completely smooth before mixing into the dough. This ensures even swirls and prevents graininess.
How do I store these bars for maximum freshness?
Keep bars in an airtight container at room temperature for up to 5 days. For longer storage, freeze them for 3 months. Wrap individual bars tightly in plastic wrap before freezing. To reheat, warm at 350°F for 5-7 minutes until the edges crisp again. The flavor actually improves after the first day!
What's the secret to getting those perfect pressed edges?
The key is pressing the dough firmly into the pan with a spatula to create a thin, even layer. Use the back of a knife to smooth the edges after adding the peanut butter swirl. Chill the dough for 15 minutes before baking—this helps it hold its shape and prevents spreading. A 9x13-inch pan works best for this classic look.
Can I make these bars without chocolate chips?
Simply omit the chocolate chips and add an extra 0.25 cup of peanut butter to maintain richness. The recipe still works perfectly—just fold in any mix-ins you prefer, like chopped nuts or white chocolate chips. The peanut butter swirl remains the star of the show!
