FREQUENTLY ASKED QUESTIONS:

How do you store them?

You can pack and store these Peanut Butter Oatmeal Fudge Bars in an airtight container. If you’re storing in layers, I recommend using a piece of parchment or wax paper in between each layer. They’ll stay fresh for about 5-6 days. No refrigeration is needed unless you live in a particularly hot and humid climate.

Can you freeze them?

You bet you can. In fact, I froze this whole batch and they were just as delicious when I served them. For ultimate freshness, I recommend only freezing cookies for about 1 month.

Can you make these gluten-free?

I don’t see why not. Unfortunately, I haven’t tested this recipe for every food allergy and/or preference. However, I assume this would be lovely with a flour alternative or even a different nut butter if you can not have peanuts. Make it your own!

Notes

*I like to do this in thin sheets of dough that I press between my hands to create an even layer with full coverage. Alternatively, you could roll the dough between two sheets of parchment paper or just crumble the mixture onto the top for a more rustic look.

  1. Love these!! I made them gluten-free and they were terrific! They freeze well too. I’m going to try freezing them with my food sealer so I can wrap them individually.
    Great re I’ve!I’ve!! Thanks!

  2. thanks for the recipe! he’s gorgeous. I made a double portion and it was eaten in ten minutes. In general, baking for me is meditation. And for my family, this is a special atmosphere and the aroma of baking, which is associated with family gatherings and hot aromatic tea.

  3. Not a lover of peanut butter but these do look absolutely delicious, you might just have converted me Michael, hope to try this recipe soon, along with some of the other wonderful creations you post.
