Line an 8-inch pan (a 9-inch one is also fine).
Combine the sugar, cracker crumbs, melted butter, and 1 cup of peanut butter until smooth. Press the mixture into the pan.
Melt the remaining peanut butter with chocolate chips, then spread over the crust.
Chill in the refrigerator for at least 2-3 hours.
Let it sit at room temperature (optionally). Cut into bars after removing from the pan.
- It can be stored in a freezer for up to 2 months. Thaw in the fridge before serving.
- You can use unsalted butter with ¼ tsp salt instead.
- Creamy peanut butter works best. Avoid oily or natural kinds for texture.
- Chunky peanut butter is okay, but the bars might be crumbly.
