So if you watch the video, you will see I only cut the bars them into 9 bars. When I make them for my family, I usually cut them MUCH smaller. I typically get between 16-20 smaller bites.

They are really filling, and if you make them too large, you will not be able to eat the whole thing. (this also helps with portion control!)

What I like to do is after I cut them, I will wrap them individually in plastic wrap and put them in the freezer. When you are ready to eat one, you can take it out a few minutes before you are ready to eat it and let it soften on the counter or eat it right from the freezer. I actually love them straight from the freezer!

Let’s discuss the simple ingredients for this healthy snack.

Ingredients for No-Bake Peanut Butter Oatmeal Bars:

Creamy Peanut Butter: The majority of the flavor and part of the glue that holds the whole operation together, unsweetened natural peanut butter is the star of the show here.

You can easily replace it with any thick, well-stirred seed or nut butter such as almond butter, sunflower seed butter, or cashew butter. Crunchy peanut butter works too!

Pure Maple Syrup or Honey: The sweetener! Pure maple syrup, honey, agave syrup, or your favorite sticky sweetener is what adds sweet flavor to these healthy peanut butter oatmeal bars.

You can scale the amount back for a lower sugar option, or increase the amount depending on how sweet you like your treats.

Oats: Old fashioned oats bring oat flavor and nutty texture to the recipe. For the best result, stick with whole rolled old-fashioned oats instead of quick oats or instant oats. I use gluten-free sprouted oats.

Hemp Seeds, Chia Seeds, or Flax Seeds (Optional): Adding an infusion of omega 3 healthy fats, hemp seeds, chia seeds, or flax seeds are an easy addition to bring a nutrient boost to the mix. You can easily omit them!

Ground Cinnamon and Sea Salt: As you’ve probably seen, I love adding ground cinnamon and sea salt to the majority of my dessert recipes because they both are flavor enhancers.

A pinch of cinnamon adds warmth and interesting nuance, and a pinch of salt brings out all of the individual flavors of each ingredient. It also makes a dessert taste sweeter without the need for added sugar.

For the Chocolate Layer: Chocolate chips and coconut oil or butter. The chocolate topping not only adds rich chocolatey goodness, but it is paramount in helping the bars stay held together nicely.

The simple combination of chocolate chips and coconut oil, coconut milk, or butter is all you need. The thick layer of chocolate really seals the deal for me.

Use your favorite semi-sweet chocolate chips, dark chocolate chips, or sugar-free chocolate chips.

Optional Additions:

Add ½ cup of chopped almonds, pecans or walnuts for a great addition bringing an additional texture element.

If you have dried fruit on hand and love a good trail mix vibe, add ½ to ⅔ cup of raisins, dried cranberries, dried blueberries, etc.

Add ½ cup of chocolate chips or cacao nibs to the oatmeal base for even more chocolate flavor.

Looking to make protein bars? Add 1 to 3 tablespoons of your favorite protein powder.

If you have vanilla extract on hand, add 1 teaspoon to the wet ingredients.

How to Make No-Bake Peanut Butter Oatmeal Bars:

Add the peanut butter and pure maple syrup to a large microwave-safe large bowl.

Microwave for 15 to 20-second intervals stirring well in between, until the ingredients mix together easily, about 40 to 60 seconds total.

Note: if you don’t own a microwave, you can prefer this step using a small saucepan and heat on the stove top over medium heat.

Transfer the peanut butter oat mixture to a 8” x 8” square pan lined with parchment paper and press it into an even layer. I used glass Tupperware, but an 8-inch pan or a 9-inch pan (for thinner bars) works great too.

Pour the chocolate mixture over the peanut butter oats and spread it into an even layer. 

Cover with plastic wrap and transfer the bars to the refrigerator and refrigerate for at least 2 hours, or until the chocolate has set up completely.

When you’re ready to cut the bars, remove them from the refrigerator and tug on the parchment paper to pull it out of the pan and transfer to a cutting board. Use a sharp knife to cut equal sized squares. Serve, and enjoy!

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.
