How to Make No-Bake Peanut Butter Oatmeal Bars

  1. Combine: In a large mixing bowl, mix together 3 cups of rolled oats, 1 cup of peanut butter, and 1/2 cup of maple syrup. Stir until everything is well-coated and sticky—this is the base for your bars!

No Bake Peanut Butter Oatmeal Bars Recipe FAQs

What kind of oats should I use?
For the best texture, I recommend using rolled oats as they provide the right chewiness. If you have dietary restrictions, opt for gluten-free rolled oats to maintain the same delicious flavor and texture without any gluten.

How long can I store No Bake Peanut Butter Oatmeal Bars?
Store your No Bake Peanut Butter Oatmeal Bars in an airtight container in the fridge for up to 1 week. They will stay fresh and chewy, making them a perfect quick snack anytime you need one!

Can I freeze these bars?
Absolutely! To freeze, arrange the bars in a single layer in a sealed container or freezer bag. They can last up to 3 months in the freezer. Before enjoying, just thaw them in the fridge overnight or for about 30 minutes at room temperature.

What if my bars are too crumbly?
If your No Bake Peanut Butter Oatmeal Bars turn out crumbly, it likely means you didn’t press the mixture down firmly enough in the pan. To remedy this, return them to the pan, press down harder, and refrigerate again for 30 minutes. If they still don’t hold together, consider adding a bit more peanut butter or maple syrup to help bind them together.

Are these bars safe for kids or people with nut allergies?
If you’re making these bars for kids or individuals with nut allergies, simply swap out the peanut butter for a nut-free option like sunbutter or soy nut butter. This way, you can still enjoy the delicious taste and chewy texture without the risk of allergic reactions.

Can I add different mix-ins to the bars?
Yes, the more the merrier! Feel free to add in your favorite mix-ins like chocolate chips, dried fruit, or chopped nuts to give your No Bake Peanut Butter Oatmeal Bars a personalized touch. Just make sure to adjust the overall consistency by slightly modifying the amounts of peanut butter and maple syrup as needed to ensure they hold together well.
