Ingredients for betty crocker peanut butter cookie bars
Sixteen no-bake bars with rich peanut butter layers and crispy cookie crusts—just these ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Creamy Peanut Butter 🥜 | 1 ½ cups | Natural or regular, not reduced-fat |
| Unsalted Butter 🧈 | ¾ cup | Melted, full-fat preferred |
| Powdered Sugar 🍚 | 1 ½ cups | Confectioners' sugar, sifted |
| Vanilla Extract 💧 | 1 tbsp | Pure extract, not imitation |
| Large Eggs 🥚 | 2 whole | Room temperature for best mixing |
| All-Purpose Flour 🌾 | 2 cups | Sifted, spooned lightly |
| Granulated Sugar 🍚 | 1 cup | For cookie crust |
| Baking Powder 🧂 | 1 tbsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Mini Chocolate Chips 🍫 | 1 cup | Optional, for customization |
| Vegetable Oil 🫒 | ¼ cup | For cookie crust |
| Milk 🥛 | ¼ cup | Any kind, room temperature |
The peanut butter is everything here. Creamy, natural brands like Jif or Skippy work best—they've got that perfect balance of richness. If you're using powdered sugar, Domino or C&H are reliable, but sift it first to avoid lumps. The butter? Full-fat is non-negotiable—it keeps the peanut butter layer gooey. I always grab extra vanilla extract from Trader Joe's because their pure extract is cheaper than the name brands. For the cookie crust, King Arthur flour gives the best texture, but any all-purpose will do. Pro tip: measure your flour by spooning it into the cup and leveling it off—don't scoop directly from the bag.
No peanut butter? Almond butter or sunflower seed butter works in a pinch, but the flavor won't be the same. Short on powdered sugar? Granulated sugar plus 1 tbsp cornstarch mimics it decently. The chocolate chips are totally optional, but if you're adding them, Hershey's Miniatures melt beautifully. For the cookie crust, if you don't have baking powder, 1.5 tsp baking soda plus 1.5 tsp cream of tartar works as a substitute. And if you're feeling fancy, swap the milk for vanilla almond milk—it adds a subtle depth. The eggs? Room temperature mixes smoother, but if you're in a rush, just let them sit out for 10 minutes.
These bars keep beautifully—5 days in the fridge, 3 months in the freezer. The peanut butter layer gets even richer after chilling, so make them a day ahead if you can. To freeze, wrap each bar individually in plastic wrap, then store in a sealed container. They thaw in about 1 hour at room temperature. For potlucks, I always pack them in layers separated by parchment paper to keep them from sticking. And if you're gifting? Cellophane bags with ribbon make them look extra special.

Step-by-step instructions for betty Crocker peanut butter cookie bars
Here's how to create rich, no-bake layers with a perfect peanut butter fudge center.
👨🍳 Step 1: Prepare the Cookie Crust
In a large bowl, combine the 1 cup granulated sugar, 2 cups all-purpose flour, 1 tbsp baking powder, and 0.5 tsp salt. Whisk until evenly distributed—you should see no more than a few flour streaks remaining. This dry mix forms the sturdy base for your bars.
In a separate bowl, melt the 0.75 cup unsalted butter with the 0.25 cup vegetable oil over low heat or in the microwave. Once fully melted, stir in the 0.25 cup milk and 1 tbsp vanilla extract until smooth. Pour this liquid mixture into the dry ingredients and stir gently until just combined—don't overmix or the crust will become tough.
Press the dough evenly into a 9x13-inch baking pan lined with parchment paper, using the bottom of a measuring cup to create an even layer. Bake at 350°F for 12-15 minutes until the edges are lightly golden. Let cool completely before adding the filling—this prevents the fudge layer from melting the crust.
👨🍳 Step 2: Make the Peanut Butter Fudge Layer
In a medium saucepan over medium heat, combine the 1.5 cups creamy peanut butter, 1.5 cups powdered sugar, and 2 whole large eggs. Stir constantly for 5-7 minutes until the mixture thickens and becomes smooth—it should coat the back of a spoon and leave a slight trail when you run your finger through it. This is your fudge base.
Remove from heat and stir in the 1 cup mini chocolate chips (if using) until evenly distributed. Here's the thing—don't skip this step. The chocolate chips add pockets of melt-in-your-mouth goodness that make these bars irresistible. Let the mixture cool slightly (about 5 minutes) until it's spreadable but still warm.
🥘 Step 3: Assemble and Chill for Perfect Texture
Spread the warm peanut butter mixture evenly over the cooled cookie crust, using a spatula to create smooth edges. The fudge should reach all the way to the edges of the pan—this ensures every bite has that rich peanut flavor. Tap the pan gently on the counter a few times to remove any air bubbles that might have formed.
Refrigerate for at least 2 hours (or up to 24 hours) until fully set. This chilling time is crucial—it allows the peanut butter to firm up while keeping the texture fudgy rather than sticky. The longer you chill, the cleaner the slices will be when you cut them later.
🔪 Step 4: Cut and Serve
Once chilled, remove the pan from the refrigerator and let it sit at room temperature for 10 minutes to soften slightly—this makes cutting easier. Use a sharp knife or pizza cutter to slice into 16 equal bars, pressing straight down without sawing. For perfectly clean cuts, dip the knife in hot water between slices.
Serve immediately or store in an airtight container in the refrigerator for up to 5 days. These bars are best enjoyed at room temperature—let them sit for 10-15 minutes before serving for the perfect balance of creamy and crunchy. The crust stays firm while the peanut butter center melts just enough to create that classic cookie bar experience.
Pro Tips For Making Betty Crocker Peanut Butter Cookie Bars
- Cream the Butter Cold: Take your unsalted butter straight from the fridge—no need to soften it first. I learned this the hard way after three batches where the dough turned greasy and spread too much in the oven. Cold butter creates flaky layers that stay put, and the bars hold their shape better when sliced.
- Measure Peanut Butter Precisely: Use a kitchen scale for the creamy peanut butter—12 ounces is not the same as 1 ½ cups. Peanut butter compacts differently, and eyeballing it leads to either a dry, crumbly mess or a sticky, underbaked disaster. Scoop it into the measuring cup, then level it off with a knife for consistency.
- Skip the Overmixing Trap: Mix the dough just until the powdered sugar and peanut butter combine—no more than 30 seconds after adding the eggs. I used to beat it like I was making cake batter, and the bars ended up dense and tough. The second the flour disappears, stop. Overworking the dough ruins the texture.
- Bake Until Golden, Not Brown: Pull the bars out when the edges are just starting to turn golden, not when they’re deep brown or pulling away from the pan. After burning two batches, I finally realized the recipe’s perfect texture comes at 325°F for 25–30 minutes—check at 25. They’ll firm up as they cool, but overbaking turns them dry.
Wine and beer pairings for these flavors
Sweet Wine Pairings
Peanut butter cookie bars pair beautifully with Moscato d'Asti—its light, fizzy sweetness complements the nutty richness without overpowering. I always reach for a chilled bottle from Bartoli or Saracco when serving these bars. The effervescence cleanses your palate between bites, making each piece taste even more decadent. 🍷
Creamy Dessert Wines
For a richer match, try a late-harvest Riesling like Dr. Loosen Blue Slate from Germany. Its honeyed notes and subtle acidity enhance the peanut butter's natural sweetness while balancing the chocolate chips. Serve slightly chilled for the best experience—these bars deserve a wine that can stand up to their indulgence.
Creamy Beer Options
A Belgian-style witbier like Hoegaarden adds a refreshing contrast with its citrusy, spiced profile. The slight tartness cuts through the peanut butter's richness, creating a perfect balance. For a stronger pairing, try a Belgian dubbel like Rodenbach—its caramel and vanilla notes mirror the cookie crust's flavors beautifully. 🍺
Coffee Pairing
If you prefer a non-alcoholic option, a dark roast coffee with 2% milk works wonders. The bitterness of the coffee enhances the peanut butter's nuttiness, while the milk softens the cookie crust's texture.
I always brew a Starbucks Sumatra or Peet's Major Dickason's Blend for this pairing—both have the right depth to complement these bars.
Ice Cream Contrast
For a dessert-within-a-dessert experience, serve with vanilla bean ice cream from Ben & Jerry's or Häagen-Dazs. The cold creaminess contrasts perfectly with the warm, fudgy peanut butter layer. I like to scoop a small portion onto each bar before serving—it adds a fun, interactive element to your dessert presentation.
Spiced Wine Option
For a festive touch, warm a mulled wine like Bartles & Jaymes and serve alongside. The cinnamon and orange notes in the wine echo the vanilla in the bars, creating a cozy, seasonal pairing.
This works especially well during holidays when you want to elevate your dessert spread with minimal effort. ✨

Frequently asked questions
Can I make these peanut butter bars without baking?
Yes! This recipe is designed to be no-bake. The cookie crust requires a 12-15 minute bake at 350°F, but the peanut butter filling sets entirely in the fridge—no oven needed after that. The chilling time is what creates that perfect fudgy texture without any baking.
How do I prevent the peanut butter layer from being too sticky?
Chilling time is key! Let the assembled bars refrigerate for at least 2 hours (up to 24 hours for best results). The longer they chill, the firmer the peanut butter becomes while staying rich and creamy. Also, make sure your peanut butter is at room temperature before mixing—this helps it set properly.
Can I substitute almond butter or sunflower seed butter?
You can try, but the flavor won't be identical. Almond butter works best for a similar texture, though it has a distinct taste. Sunflower seed butter is too mild and can make the bars taste bland. If substituting, reduce the powdered sugar by 1-2 tablespoons since nut butters vary in sweetness.
Why did my cookie crust turn out crumbly?
Overmixing the crust or using too much flour can make it crumbly. Measure your flour by spooning and leveling (don't scoop directly from the bag), and mix just until combined. Also, ensure your butter is fully melted but not hot—it should be warm to the touch but not greasy. A 12-15 minute bake at 350°F should give you a sturdy base.
How can I make these bars nut-free for allergies?
Replace the peanut butter with an equal amount of sunflower seed butter or tahini (for a sesame flavor). For the cookie crust, use sunflower seed butter instead of peanut butter in the filling. Always check labels to ensure all ingredients are nut-free, especially chocolate chips.
