Ingredients for Classic No-Bake Peanut Butter Bars
To make the best No-Bake Peanut Butter Bars, you’ll need only a few ingredients, most of which you likely already have:
For the base:
- 1 cup unsalted butter (melted)
- 2 cups graham cracker crumbs
- 2 cups powdered sugar
- 1 1/2 cups creamy peanut butter
For the chocolate topping:

These ingredients come together to create the iconic two-layer bar with a rich peanut butter base and a glossy chocolate top.
Step-by-Step Recipe: No-Bake Peanut Butter Bars
Step 1: Prepare the Peanut Butter Base
In a medium bowl, combine melted butter, graham cracker crumbs, powdered sugar, and peanut butter. Stir until the mixture is smooth and uniform.
Step 2: Press into a Pan
Line an 8×8-inch baking pan with parchment paper. Press the peanut butter mixture evenly into the bottom of the pan using the back of a spoon or a spatula.
Step 3: Make the Chocolate Topping
In a microwave-safe bowl, combine chocolate chips and peanut butter. Microwave in 30-second intervals, stirring each time, until smooth.
Step 4: Spread and Chill
Pour the chocolate mixture over the peanut butter layer. Spread evenly. Chill in the refrigerator for at least 2 hours or until firm.
Step 5: Slice and Serve
Once fully set, lift the bars out of the pan and cut into squares. Store in the refrigerator for up to one week.
