FREQUENTLY ASKED QUESTIONS:

Do these need to be refrigerated?

Yes. I have found that refrigeration helps the bars firm up and hold their shape. Once set, keep them stored in the refrigerator for best texture.

Can these bars be frozen?

Yes! These bars freeze well. Cut them into desired size first, then store in a freezer safe container for up to 3 months. Thaw in the refrigerator before serving.

Can I use quick oats instead of old-fashioned oats?

Yes, but the texture will be softer. Old-fashioned oats create chewier bars, while quick oats result in a more tender, compact texture.

Can I add mix-in’s to this recipe?

Absolutely. Chocolate chips, nuts, coconut, or dried fruit all work well. Stir them in before pressing the mixture into the pan.
