FAQs
Q: Can I use natural peanut butter?
A: You can, but texture may change. Natural peanut butter can make the dough a bit softer.
Q: Can I use a different size pan?
A: A 9×9 inch pan is best. A larger pan will make thinner bars and reduce bake time a little.
Q: Do I need to chill the dough?
A: No, this recipe bakes well without chilling. Chill only if dough is too soft to press.
Q: Can I use mini M&M’s?
A: Yes, mini M&M’s work fine and spread more evenly through the dough.
