Method
- Step 1: In a large mixing bowl, add 1 cup of creamy peanut butter and 1/2 cup of softened unsalted butter. Using an electric mixer or a whisk, beat the mixture until it becomes smooth and creamy.
- Step 2: Gradually add 1 cup of powdered sugar, 1 cup of graham cracker crumbs, and 1 teaspoon of vanilla extract to the peanut butter mixture. Mix until fully combined and the mixture is smooth.
- Step 3: Press the mixture evenly into the bottom of a greased 9x9-inch baking pan.
- Step 4: In a microwave-safe bowl, combine 1 cup of semisweet chocolate chips and 1 tablespoon of vegetable oil. Microwave in 30-second intervals, stirring between each, until the chocolate is completely melted and smooth.
- Step 5: In another microwave-safe bowl, combine 1 cup of white chocolate chips and the remaining tablespoon of vegetable oil. Repeat the microwaving process until the white chocolate is melted and smooth.
- Step 6: Drop spoonfuls of the melted semisweet chocolate and white chocolate over the peanut butter layer. Use a toothpick or skewer to swirl the two chocolates together, creating a marbled effect.
- Step 7: Refrigerate the pan for at least 2 hours, or until the bars are fully set.
- Step 8: After the bars are set, remove them from the refrigerator and cut them into squares.
Notes
Store your bars in an airtight container in the refrigerator. They will stay fresh for up to one week.
