Peanut Butter Lunch Lady Bars: No-Bake

Instructions:

1. Combine the graham cracker crumbs, creamy peanut butter, powdered sugar, and melted butter in a large bowl.
2. Mix until the ingredients form a thick, sandy paste.
3. Press the mixture firmly into a parchment-lined 9x13 inch pan, smoothing the top until it is completely level.
4. Place the pan in the refrigerator for 30 minutes to firm up.
5. In a microwave-safe bowl, combine the semi-sweet chocolate chips and the additional ¼ cup of peanut butter.
6. Microwave in 20-second bursts, stirring between each interval, until the mixture is a smooth, velvety liquid.
7. Pour the melted chocolate mixture over the chilled peanut butter base.
8. Use a spatula to spread the chocolate evenly to the edges.
9. Return the pan to the refrigerator for at least 90 minutes, or until the chocolate is set to the touch.
10. Lift the parchment paper to remove the block and slice into 24 equal squares.
