Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

• 10 tablespoons butter, room temperature, divided
• 1 ½ cups graham cracker crumbs
• 1 ¾ cups powdered sugar
• 1 ½ cups creamy peanut butter
• 1 cup semi-sweet or milk chocolate chips

Directions

1. Line an 8-inch or 9-inch square baking pan with foil or parchment paper and lightly coat with nonstick spray.
2. In a large bowl, beat together 5 tablespoons of butter, graham cracker crumbs, and powdered sugar until smooth and well combined.
3. Stir in peanut butter until the mixture forms a thick, cohesive filling.
4. Press the peanut butter mixture evenly into the prepared pan, smoothing the top with a spatula.
5. In a microwave-safe bowl, combine chocolate chips and the remaining 5 tablespoons of butter. Heat for 1 minute, then stir. Continue heating in 30-second intervals, stirring between each, until completely melted and smooth.
6. Pour the melted chocolate over the peanut butter layer and spread evenly.
7. Refrigerate until firm, at least 3 hours or overnight.
8. Before serving, let the bars stand at room temperature for about 10 minutes to make cutting easier. Slice into squares and enjoy.

Storage/Reheating

• Refrigerator: Store covered in the refrigerator for up to 2–3 weeks.

FAQs

1. Can I use natural peanut butter?

Yes, but natural peanut butter can be oilier and may prevent the bars from setting properly. Stir it thoroughly before using or add extra powdered sugar to help firm the mixture.

2. What can I use instead of graham cracker crumbs?

You can substitute crushed digestive biscuits, vanilla wafers, or even finely crushed pretzels for a salty twist.

3. My bars didn’t set properly—what went wrong?

This often happens if too much oil is in the peanut butter or the mixture wasn’t chilled long enough. Extend chilling time or add a bit more powdered sugar next time.

4. Can I make these ahead of time?

Absolutely! These bars are great for make-ahead desserts. Prepare them a day in advance and chill overnight for best texture.

5. How should I cut clean slices?

Run a sharp knife under warm water, wipe it dry, then slice. Clean the knife between cuts for smooth edges.

6. Can I double the recipe?

Yes, double all ingredients and use a 9×13-inch pan. Chill slightly longer to ensure the center sets fully.

7. Can I use white chocolate instead of milk or semi-sweet?

Yes, though the flavor will be much sweeter and less balanced. Pair with slightly salted peanut butter for contrast.

8. Are these gluten-free?

Use gluten-free graham crackers or crumbs to make this recipe gluten-free.

9. Can I add other mix-ins?

Chopped nuts, crushed pretzels, or mini marshmallows can be added to the peanut butter layer for extra crunch and flavor.

10. How long can they sit out at a party?

They can safely sit out for about 1–2 hours depending on the room temperature. In warmer environments, keep them refrigerated until serving.
