- 1 cup butter, melted: Provides moisture and richness for the base layer.
- 1 1/2 cups graham cracker crumbs: Adds a subtle sweetness and crunchy texture to the bars.
- 1 to 1 1/2 cups powdered sugar: Sweetens the base and helps bind it together.

How to Make Peanut Butter Chocolate Bars Recipe
Step 1: Make the Base Mixture
Start by mixing together the melted butter, graham cracker crumbs, powdered sugar, and 1 cup of peanut butter in a large bowl. This combination forms the sturdy and flavorful foundation of your bars, setting the stage for the chocolate topping.
Step 2: Press Into the Pan
Once your base mixture is smooth and combined, press it evenly into the bottom of a 9 x 13-inch pan. Taking your time here ensures a consistent thickness, which helps each bar hold together beautifully when cut.
Step 3: Melt the Chocolate and Peanut Butter
For the decadent topping, combine the remaining 1 cup of peanut butter with the semisweet chocolate chips in a microwave-safe bowl. Heat in 30-second increments, stirring each time until you achieve a silky, homogeneous mixture. This step is crucial for avoiding burnt chocolate and maintaining a perfect texture.
Step 4: Pour and Spread the Topping
Pour the warm chocolate and peanut butter blend over your prepared base. Use a spatula to spread it evenly to all corners of the pan. This smooth layer contrasts wonderfully with the crumbly base and adds that irresistible visual appeal.
Step 5: Chill Until Firm
Place the pan in the refrigerator for 1 to 2 hours. This chilling time allows the chocolate topping to set firmly and the bars to hold their shape when sliced.
Step 6: Cut Into Bars
After chilling, remove the pan and cut the dessert into 54 bars or whatever size you prefer. Using a sharp knife helps produce neat edges and clean cuts, perfect for serving.
Step 7: Store and Serve
Store your bars in the fridge or freezer, keeping them chilled to maintain their delightful texture. They’re best enjoyed cold, providing a refreshing bite on warm days or after meals.
How to Serve Peanut Butter Chocolate Bars Recipe

Garnishes
Add a touch of flair with a few simple garnishes. A sprinkle of crushed peanuts or a light dusting of powdered sugar can elevate the presentation and add an extra layer of texture and flavor without overwhelming the bars.
Side Dishes
Pair your peanut butter chocolate bars with a scoop of vanilla ice cream or a dollop of whipped cream. The creamy coldness balances the richness and sweetness of the bars, making each bite a delightful experience.
Creative Ways to Present
For a fun twist, serve these bars on decorative trays lined with parchment paper or cut them into bite-sized squares for party platters. You can also drizzle extra melted chocolate on top before chilling, adding a marbled effect that’s both beautiful and tasty.
Make Ahead and Storage
Storing Leftovers
Once prepared, these bars keep extremely well in the refrigerator for up to a week. Store them in an airtight container to maintain freshness and to prevent them from absorbing any other fridge odors.
Freezing
You can freeze the bars for up to 2 months. Wrap individual bars or the whole pan securely in plastic wrap and place in a freezer-safe container. This makes them great for prepping ahead of time or for keeping on hand for last-minute treats.
Reheating
Since these bars are best enjoyed chilled, reheating isn’t necessary. If you prefer a softened texture, simply leave them at room temperature for 10 to 15 minutes before serving. This helps the chocolate and peanut butter layers become more tender without melting away.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Crunchy peanut butter will add extra texture to the bars, giving them a bit more bite. Just know that the bars may be slightly less smooth but equally delicious.
Is it possible to substitute graham crackers with another ingredient?
You can use digestive biscuits or even crushed vanilla wafers as a substitute for graham cracker crumbs. Each will slightly alter the flavor and texture but still provide a great base for the bars.
Do I have to use the microwave to melt the chocolate and peanut butter?
No, you can melt the mixture gently using a double boiler on the stove for more control and to prevent scorching. Just stir frequently until smooth and fully combined.
How long will these bars stay fresh at room temperature?
Because of the buttery and peanut butter content, it’s best to keep the bars refrigerated. At room temperature, they may become too soft and lose their structure within a day or two.
Can I make this recipe vegan or dairy-free?
Yes! Use plant-based butter and dairy-free chocolate chips to transform this recipe into a vegan treat. Just make sure your peanut butter remains natural and free from added dairy ingredients.
