We recently tried some No Bake Chocolate Oat Bars that the entire family loved, and I wanted to share the recipe with y’all today.

These Oat bars were like a more chocolate-y and delicious granola bar, which means they were loved by all. Layers of oat and chocolate all topped off with a drizzle of even more chocolate made up this yummy dessert.

The best part? NO BAKING involved!! Not only are these perfect for summer time, but they’re great all year long and can give you the feel of a delicious baked chocolate and oat treat without actually having to bake them!

The thick layer of chocolate in the middle is definitely my favorite part (how could it not be?)!! We hope you can give these a try and enjoy a delicious treat without heating up the house. 😉

Making No Bake Bars

PREP. Grease a 9×9 inch pan and set aside.

OATS. In a medium pot, melt butter. Stir in brown sugar and vanilla. Add oats and cook on low for a few minutes. Pour half of this mixture into the greased pan and press down with spatula. Set aside reserve.

CHOCOLATE. In another pot, melt chocolate chips and peanut butter on low. Stir until smooth and pour over bottom oat layer. Crumble the remaining oat mixture over the chocolate layer, pressing in gently.

DRIZZLE. Melt chocolate chips and drizzle over top.

ENJOY! Cover, and refrigerate for a few hours. Bring bars to room temp before cutting and ENJOY!

Tips + Variations

We used quick cooking oats, but you can use rolled/old fashioned oats.  Quick oats are the most processed of all the oat types and also take the shortest amount of time to cook. If you wanted to use old fashioned/rolled oats add a couple extra minutes of cook time in step 2 to soften them up. 

Unlike some layer bars these don’t need extra time to set before piling on the next layer. This is because you want the oats to really be a part of the chocolate layer, which is only possible when they have the opportunity to meld together. 

Line the pan with parchment paper. Once the bars have set, all you have to do is lift them out using the paper and cut them. Easy Peasy.

Dress ’em up: We topped these delicious bars with a chocolate drizzle. You can get creative with what you would use such as:

  • Caramel Drizzle
  • Butterscotch Chips
  • Mini M&M’s

Storing Info

STORE the bars at room temperature in an airtight container for 3-5 days. They will last even longer if stored in the fridge. Finally, they can easily be wrapped and stored in the freezer for 2-3 months. 

Wrap the entire bar with plastic wrap or cut it into individual bars and wrap those. Fold top sandwich baggies also work for the individual sizes. FREEZE either wrapped again with foil or place them together in a freezer Ziploc. Thaw before eating.

These would be a great thing to pack into your kiddos’ lunches. Just make sure to send them with an ice-pack so it doesn’t melt all over everything else in the lunchbox

  1. I just made this for my daughter in law to have after having our baby. I’m excited for her to try these.
    Thank you

    1. Yes, you can double the recipe. You’ll want to use a larger pan than a 9×9 (unless using two 9×9 pans). The original recipe calls for 1 cup of butter (which is 2 sticks), so doubling the recipe would actually be 2 cups (or 4 sticks) of butter.

  2. Tried making these but a cup of butter was way too much. I had to drain some off before putting the oats in the pan. Also, I wish the instructions suggested to use parchment paper instead of there just being a picture of it. I missed the picture and getting them out of the pan is kind of a pain lol. Tasty though!
