FAQs
Can I use natural peanut butter in this recipe?
Natural peanut butter tends to be thinner and may affect the texture. It’s best to use creamy peanut butter to ensure the mixture binds well.
Do I need to refrigerate the bars?
Refrigeration helps the bars set faster and keeps the chocolate topping firm, but they can also set at room temperature if left undisturbed.

Instructions
- Prepare Pan: Grease an 8-inch square pan thoroughly and set aside to prevent sticking.
