“The best no bake chocolate oat bars recipe. It had the best texture ever!!!” – Ariana
Table of Contents
My chocolate oatmeal bars recipe is made from a mixture of oats, chocolate chips, maple syrup, and peanut butter that are pressed into a baking pan and chilled until they become firm and chewy.
They are super versatile and take less than five minutes of prep work. Taste-wise, they are sweet and LOADED with chocolate and peanut butter flavor. In terms of texture, they are somewhat chewy, thick, and satisfying- you won’t stop at one!
If you love no bake desserts, try my no bake oatmeal cookies, 3 ingredient peanut butter balls, no bake brownie bites, and no bake brownies next.

Nutrition
Ingredients needed
- Rolled Oats. Also known as old-fashioned oats. They give the oatmeal bars the ideal chewy texture. You can use quick-cooking oats if that is all you have on hand.
- Peanut Butter. Opt for the smooth and creamy variety with no added sugar. If you can’t tolerate peanuts or aren’t a fan of them, you can use almond butter or cashew butter. If you’d like these bars to be completely nut-free, try using tahini or sunflower seed butter.
- Chocolate Chips. Any chocolate chips of choice will work. I typically use semi-sweet chocolate chips.
- Pure maple syrup. A liquid sweetener makes the bars smoother to bite into, along with some creaminess. Honey will also work.
- Coconut Oil. Keeps the bars stable at room temperature but is also easier to bite into. Opt for refined coconut oil to ensure there is no coconut flavor. You can also use unsalted butter.
How to make no bake chocolate oat bars

Step 1- Prep. Melt the peanut butter, coconut oil, chocolate chips, and maple syrup.

Step 2- Combine. Stir through the oats and mix well.

Step 3- Assemble. Transfer the chocolate mixture into a lined pan and refrigerate for at least 30 minutes to firm up.

Step 4- Slice. Once firm, slice up into bars.
Arman’s recipe tips
- Use a slightly wet knife to slice these into bars. It will make it so much easier to cut into.
- Microwave the chocolate mixture in short increments. Chocolate can burn quite easily, so I like to microwave the chocolate in 20-second increments until it’s mostly melted.
- Add extra mix-ins like chopped nuts, candy pieces, or dried fruits.
Storage instructions
To store: Leftover bars in a sealed container can keep well at room temperature. They will stay well and covered for up to 1 week. To keep them longer, store them in the refrigerator.
To freeze: Place chocolate oat bars in a freezer-friendly container or ziplock bag, and store them in the freezer. They will keep well frozen for up to 6 months.

No, I don’t recommend baking these bars. They will turn out dense and greasy.

The best no bake chocolate oat bars recipe. It had the best texture ever!!!
Love all your recipes, they’re tasty, healthy and easy to make! I have an unhealthy question to ask, can some of the ingredients get substituted for snickers bar and butter? Apologies if this is offensive!
Not offensive at all! Yes, we can transform this into a snickers slice. Swap out half the oats for chopped up snickers pieces and also some extra nuts 🙂
