These bars combine the classic pairing of peanut butter and chocolate in a no-fuss format.

The result is a firm, sliceable bar with a creamy peanut center and a glossy chocolate top.

The recipe is a family favorite and simple enough to make with kids.

These peanut butter bars are quick to make and taste like they took much more effort. They are ideal for potlucks, game days, bake sales, or casual entertaining. You can make them ahead and refrigerate or freeze them for later. They also travel well for picnics and road trips.

How to Make

To prepare the bars you will need the following ingredients:

  • 1 cup (226 g) butter, melted
  • 2 cups (200 g) graham cracker crumbs (about 2 sleeves ground to a fine crumb)
  • 2 cups (227 g) confectioners’ sugar
  • 1 1/2 cups (405 g) peanut butter
  • For the chocolate topping: 1/4 cup (68 g) peanut butter and 2 cups (340 g) chocolate chips

Mix the base. In a large mixing bowl, combine the melted butter, graham cracker crumbs, confectioners’ sugar, and 1 1/2 cups peanut butter. Stir until the mixture is smooth and well combined. Press the mixture evenly into a 9×13-inch baking dish to form a compact base.

Prepare the topping. In a medium microwave-safe bowl, combine the chocolate chips and 1/4 cup peanut butter. Melt in the microwave at 80% power in 1-minute intervals, stirring between each interval, until the mixture is smooth and glossy.

Assemble and chill. Spread the melted chocolate-peanut butter mixture evenly over the prepared peanut butter base. Place the dish in the freezer for about 15 minutes, or until the topping is set and firm enough to slice.

Slice and serve. Remove the pan from the freezer and cut into individual bars. The number of bars will vary depending on your preferred size—this recipe typically makes between 20 and 36 bars. Store on the counter for a short time or refrigerate if your environment is warm to keep the chocolate from softening.

Storage Tips

To store: Keep the bars in an airtight container on the counter for a few days, or in the refrigerator if you prefer a firmer texture or if your kitchen is warm. Refrigeration helps the chocolate remain firm.

To freeze: Place bars in a freezer-safe container or wrap individually, label with the date, and freeze for up to 3 months. Thaw in the refrigerator or at room temperature before serving.

These bars are flexible and forgiving. If you prefer crunchy texture, use crunchy peanut butter, or swap graham cracker crumbs for cookie crumbs of your choice. You can also sprinkle a little flaky sea salt on top of the chocolate for a salty-sweet contrast.
