Directions
1. In a large mixing bowl, combine the melted butter and peanut butter until smooth and well blended.
2. Add the powdered sugar and graham cracker crumbs to the peanut butter mixture, stirring until fully combined.
3. Press the mixture evenly into a 9×13-inch baking dish, creating a firm base.
4. In a microwave-safe bowl, melt the chocolate chips in 30-second intervals, stirring in between, until smooth.
5. Pour the melted chocolate over the peanut butter base, spreading it evenly with a spatula.
6. Refrigerate the bars for at least 2 hours or until the chocolate is set.
7. Once set, cut into squares and serve.
Variations & Tips
For a crunchy texture, you can add chopped peanuts to the peanut butter mixture. If you prefer a sweeter bar, try using milk chocolate chips instead of semi-sweet. For those with dietary restrictions, you can substitute gluten-free graham cracker crumbs and dairy-free chocolate chips. To make it more festive, sprinkle some sea salt or colorful sprinkles on top of the chocolate layer before it sets.
