No Bake Peanut Butter Oatmeal Bars

No bake peanut butter oatmeal bars are a quick and tasty no bake treat. With a chewy texture and the perfect balance of savory peanut butter and sweet honey they are great for an afternoon pick me up, post workout recharge, or breakfast on the go. These bars are made from five simple ingredients that you probably have in your pantry. Only 10 minutes to make plus thirty minutes to cool, means you are closer to a homemade snack than you thought!

Originally appearing on the blog in March 2016, the post was last updated in May 2020. The recipe has been simplified, but no major changes.

When I see the words peanut butter and honey combined, I know I’m in for a tasty treat. It’s a sweet and savory combination that I loved as a kid and haven’t outgrown to this day. It’s also the inspiration behind these super simple, no bake peanut butter oatmeal bars.

When I set out to make these bars the first time, I was in need of a quick post-hike treat. It had to be something homemade so that I could control the ingredients. It also needed to provide enough energy to hold us until dinner, while not being a complete calorie bomb.

My initial thought was a chewy granola bar, but I didn’t have dried fruit, nuts, or chocolate on hand, all the things that make granola, granola. Luckily, simplicity can be delicious. These no bake oatmeal bars have everything they need, nothing more and nothing less.

Making Homemade Oatmeal Bars

Making these no bake oatmeal bars requires only five ingredients and it’s easier than making my ultimate holiday Rice Krispies treats. You will need a large mixing bowl, a small saucepan, a heat proof spoon, a square cake pan, and a sheet of parchment paper.

You simply heat the peanut butter and honey over a medium flame, stirring until it reaches a smooth consistency. Remove from the flame before adding in the salt and vanilla. Fold the peanut butter mixture into the oats mixture to combine completely, then press out in the parchment lined pan. Cool completely and enjoy.

Peanut Butter Oatmeal Bars FAQs

Can I make these in the microwave?

Yes! The reason for heating the peanut butter and honey is to make it easier to mix. Use a microwave safe bowl. Microwave in 20 second burst, stirring in between, until the mixture is smooth and hot, then add the salt and vanilla before combining with the oats.

What if I don’t have parchment paper?

You could grease the pan with a solid fat like coconut oil or butter, or spray with an oil mister. The bars may crumble a bit as you take them out, but they will still taste good!

Can I swap in a different sweetner?

Yes! I have not extensively tested other sweeteners, but I do an oatmeal ball version of these with maple syrup. I’m not sure how sugar or simple syrup would do because of the texture, but I could imagine it would work with molasses, corn syrup, or other sweeteners with a similar texture.

Can I use sunbutter, almond butter, cashew butter, or any other type of nut butter?

Absolutely! As long as it’s thick and creamy like peanut butter it will hold together the oats.

Can I use this recipe to make oatmeal balls instead of oatmeal bars?

Yes! You can shape the dough (mixture?) into balls the same way you would cookie dough. Be advised: work quickly. As the mixture cools it doesn’t stick together as well.

Can I freeze these for later?

Yes! Freeze them in a freezer friendly container and they should keep for a couple months. They thaw out well without compromising the texture, but oddly enough, they taste good while frozen too.

How should I store them?

Storing them in the fridge is going to give them a firmer shape and a chewier texture. Storing them at room temperature can make them soft if the room is too warm, but it’s perfectly safe for these shelf stable ingredients. It’s totally up to you, but I like them in the fridge.

What if I don’t have a square cake pan?

I would try a 8″ round cake pan or a 9×5 loaf pan. You want it to be thin enough that you can cut it into portion sizes, but not so thin that it will fall apart. Alternatively, you could skip the pan and roll it into balls like you would cookie dough.

Janice,

I haven't had them stick around long enough to freeze, but I do have them scheduled for an update with new photos in two weeks. I'll make sure to test and find out for you. If you try it, let me know!
