Ingredients for betty crocker peanut butter cookie bars
Five core ingredients plus optional add-ins create nostalgic, swirled peanut butter cookie bars.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 cups | Sifted for even texture |
| Granulated Sugar 🍚 | 1 ½ cups | Light brown sugar for chewiness |
| Creamy Peanut Butter 🥜 | 1 cup | Natural, no added sugar |
| Unsalted Butter 🧈 | 1 cup | Softened, not melted |
| Pure Vanilla Extract 🍯 | 1 tsp | High-quality, imitated preferred |
| Large Eggs 🥚 | 2 whole | Room temperature for blending |
| Flaky Sea Salt 🧂 | ½ tsp | For finishing top layer |
| Semisweet Chocolate Chips 🍫 | 1 cup | Optional for extra richness |
| Chopped Peanuts 🥜 | ½ cup | Optional for texture contrast |
| Baking Soda 🧪 | ½ tsp | For proper leavening |
| Ground Cinnamon 🌿 | ½ tsp | Enhances peanut butter flavor |
The peanut butter is the star—opt for natural, no-sugar-added brands like Smucker's or Jif for authentic flavor. If you prefer extra richness, Crisco shortening can replace half the butter without compromising texture. For the flour, King Arthur or Gold Medal brands provide consistent results. The chocolate chips? Hershey's Special Dark or Ghirardelli add depth, but any quality brand works. If you're skipping the optional nuts, ensure the peanut butter is smooth and creamy for proper swirling.
No peanut butter? Almond butter or sunflower seed butter works in a pinch, though texture may vary slightly. Short on vanilla? Almond extract at half the amount mimics the flavor profile. The chocolate chips can be swapped for white chocolate chips or chopped nuts—just adjust the quantity to taste. For a gluten-free version, Bob's Red Mill 1:1 baking flour replaces all-purpose flour without altering the structure. The baking soda and cinnamon are non-negotiable; they balance sweetness and enhance the peanut butter's warmth.
Peanut butter dough keeps for 5 days in an airtight container, while baked bars stay fresh for 7 days at room temperature. For longer storage, freeze the bars in slices for up to 3 months. To reheat, wrap individual slices in foil and warm for 10-15 seconds in the microwave. These bars also freeze beautifully before baking—simply thaw at room temperature before serving.

Step-by-step instructions for Betty Crocker peanut butter cookie bars
Here's how to create rich, creamy peanut butter cookie bars with a perfect swirl pattern in one pan.
Prepare the Peanut Butter Cookie Dough
In a large mixing bowl, combine the 1 cup unsalted butter and 1.5 cups granulated sugar. Cream together using an electric mixer on medium speed for 3-4 minutes until light and fluffy. The mixture should nearly double in volume and become pale in color. This step incorporates air, which creates the tender texture these bars are known for.
Add the 1 cup creamy peanut butter, 1 tsp pure vanilla extract, and 2 whole large eggs one at a time, mixing well after each addition. The peanut butter should blend smoothly into the mixture, creating a rich, nutty base. Scrape down the sides of the bowl with a spatula to ensure even mixing.
In a separate small bowl, whisk together the 2 cups all-purpose flour, 0.5 tsp baking soda, and 0.5 tsp ground cinnamon. Gradually add this dry mixture to the peanut butter mixture, mixing on low speed just until combined. Avoid overmixing, as this can develop gluten and make the bars tough. The dough should be thick and smooth.
Create the Chocolate Swirl Dough
In the same mixing bowl, fold in 1 cup semisweet chocolate chips using a spatula until evenly distributed throughout the peanut butter dough. Set aside 0.5 cup chopped peanuts for the topping. The chocolate chips will create pockets of rich, melty goodness throughout each bar.
For the chocolate swirl layer, take half of the peanut butter dough and place it in a medium-sized mixing bowl. Fold in 0.5 cup chopped peanuts until evenly distributed. This will create a contrasting texture in the finished bars. Set this aside for now.
Assemble and Bake the Cookie Bars
Preheat your oven to 350°F and line a 9x13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Spread the remaining peanut butter dough evenly into the prepared pan, using a spatula to press it into the corners. This will form the base layer of your bars.
Drop spoonfuls of the chocolate swirl dough onto the peanut butter layer, spacing them about 2 inches apart. Use the back of a spoon to gently swirl the chocolate dough into the peanut butter layer, creating marbled patterns. This step is key to achieving those beautiful swirls that make these bars so appealing.
Finish and Bake to Golden Perfection
Bake the cookie bars for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with a few moist crumbs (not wet batter). The center should be slightly underbaked to maintain that creamy texture. Rotate the pan halfway through baking for even cooking.
Remove the bars from the oven and let them cool in the pan for 15 minutes. While still warm, sprinkle the 0.5 tsp flaky sea salt evenly over the top. The contrast of salty and sweet enhances the flavors dramatically. Allow the bars to cool completely before slicing into 16 equal-sized bars for serving.
Pro Tips For Making Betty Crocker Peanut Butter Cookie Bars
- MEASURE PEANUT BUTTER PRECISELY: Use a kitchen scale for the peanut butter—12 ounces is not the same as 1.5 cups. Creamy peanut butter compacts differently, and eyeballing it means your bars could turn out too thick or dry. (I learned this after making a batch that looked like a brick.)
- CREAM BUTTER AND SUGAR UNTIL PALE: Beat the butter and sugar until they’re light and fluffy, not just combined. You’ll know it’s ready when the mixture leaves a clean ribbon trail when you lift the beaters—this ensures your bars stay tender, not cakey. (Yes, it takes longer, but it’s worth it.)
- DON’T OVERMIX THE DOUGH: Once you add the flour, mix just until it comes together. Overmixing develops gluten, and your bars will turn out tough instead of chewy. Stop when there are still a few flour streaks—this keeps the texture perfect.
- BAKE UNTIL EDGES ARE GOLDEN: The recipe might say "brown," but aim for edges that are golden, not burnt. Use an oven thermometer to confirm it’s 350°F—many home ovens run hot. Pull them out when the center still looks slightly underdone; they’ll firm up as they cool. (I’ve ruined batches by waiting too long.)
Perfect pairings for these flavors
Classic Ice Cream
These bars pair perfectly with vanilla ice cream—the creamy, cool contrast balances the peanut butter's richness. I recommend Blue Bell Homemade Vanilla or Breyer's Natural Vanilla for that classic diner-style experience.
Scoop a generous portion alongside each slice, or drizzle melted ice cream over the top for a decadent dessert. 🍦
Chocolate Dipping Sauce
Warm up ½ cup heavy cream with ½ cup chopped dark chocolate (like Ghirardelli 60% Cacao) until silky smooth. This chocolate ganache turns every bite into a dessert experience.
Dip the corners of each bar for a gourmet touch, or drizzle it over the top before serving. The bitterness of dark chocolate complements the peanut butter beautifully.
Coffee or Tea
A hot cup of coffee or black tea makes these bars feel like an after-dinner treat. For coffee lovers, a medium-roast blend like Starbucks Pike Place enhances the peanut butter's nuttiness.
If you prefer tea, Earl Grey or chamomile adds a sophisticated contrast to the sweetness. The warmth of the drink cuts through the richness, balancing the flavors perfectly. ☕
Fresh Fruit
Add a light, refreshing element by serving with sliced strawberries or banana slices. The natural sweetness and acidity of fruit—especially strawberries or pineapple chunks—brightens the peanut butter's richness. I like to arrange fruit on a platter alongside the bars for a visually appealing dessert spread. 🍓
Nutty Toppings
For extra texture, sprinkle crushed peanuts or chopped almonds over the top before serving. The crunch contrasts the soft, chewy bars beautifully. If you're feeling adventurous, add a drizzle of peanut butter glaze (melt ¼ cup peanut butter with 1 tbsp honey and brush it on top).
This adds a glossy finish and intensifies the peanut flavor. 🥜
Warm Milk or Hot Chocolate
For a cozy, nostalgic touch, serve these bars with warm milk or hot chocolate. The warmth of the drink enhances the peanut butter's comforting qualities, making it feel like a childhood treat.
For hot chocolate, use Ghirardelli Premium Cocoa Mix and top with whipped cream for the ultimate indulgence. 🥛

Frequently asked questions
Can I make these bars without chocolate chips?
The chocolate swirl is what makes these bars special, but you can absolutely skip the chips! Replace them with ½ cup chopped walnuts or white chocolate chips for a different flavor profile. Just remember to fold the substitute into the peanut butter dough before swirling. The texture will be slightly different but still delicious.
Why did my peanut butter cookie bars turn out too dry?
Overbaking is the most common cause of dry bars. These should have a slightly underbaked center—test with a toothpick for moist crumbs, not dry ones. If your oven runs hot, reduce the temperature to 325°F and check at 22 minutes. Also, ensure your peanut butter is creamy (not crunchy) for proper moisture.
How do I store these bars for maximum freshness?
Keep baked bars in an airtight container at room temperature for up to 7 days. For longer storage, slice the bars and freeze them for up to 3 months. Thaw at room temperature before serving. The peanut butter flavor actually improves slightly after 2-3 days!
Can I make these bars gluten-free?
Yes! Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill). For best results, add ½ tsp xanthan gum to the mix. The texture will be slightly denser but still chewy. Test with a small batch first to adjust sweetness if needed.
What's the secret to getting those perfect swirls?
Use a spoon or small offset spatula to gently drag the chocolate dough through the peanut butter layer in broad, sweeping motions. Work quickly but carefully—overmixing can break the swirls. For extra drama, chill the dough for 30 minutes before baking to help the layers hold their shape.
