The love I have for these peanut butter and chocolate filled oat bars is limitless. Not only is there absolutely no baking required – major plus! – but they’re also loaded with nostalgia.

There is nothing better than the warm and fuzzies brought on by reminiscing over childhood memories while you are indulging, don’t you think?

I grew up in a semi-quiet (except for us kids running around) oval shaped neighborhood. Once upon a time, a new girl showed up and everyone wanted to be her friend.

In a small town like ours, the allure of a new person is so great. Lucky for me, we became fast friends. We’d spend evenings after school racing our bikes from her house to mine and playing in the backyard. 

While we played, her mom would be tinkering in the kitchen.

As our friendship grew, her mom introduced me to new desserts and some fantastic foods. And of all her creations, these chocolate and peanut butter oatmeal bars have got to me my absolute favorite.

Sometimes my cravings tell me that I am ten years old and I want (read need) these bars.

Now, if you’re willing, I invite you to really jump down the nostalgia rabbit hole with me and whip up some baked macaroni and cheese along with these no-bake bars. Prepare to be transported way way back!

Now, without further ado, I present to you a fantastic childhood memory: No-Bake Chocolate and Peanut Butter Oat Bars.

I’m curious, do you have a specific food that is deeply rooted in your childhood?

WHY WON’T MY NO-BAKE OATMEAL BARS HARDEN?

When I say “refrigerate the bars for at least 3 hours,” I mean it. It may seem too long to wait to cram one of these tasty treats into your face, but it’s worth the wait. Allowing the bars to set up completely will make them easier to cut.

HOW DO I STORE NO-BAKE OATMEAL BARS?

Once the bars have been frozen and cut, they can be stored in an airtight container, either in the fridge or at room temperature. In the warmer months, you may want to keep them in the fridge, because they melt quickly.

CAN I USE WAX PAPER INSTEAD OF PARCHMENT?

Wax paper will work for this recipe. Be sure the waxy side goes up though to avoid sticking.

CAN THESE BE MADE WITH GLUTEN-FREE OATS?

Gluten-free oats can be used, but the finished product will be a little different. The lack of gluten will change the chewiness and moisture content. 

CAN I USE CRUNCHY PEANUT BUTTER?

Sure you can! I think you might be on to something great here actually. If you try this, let me know how it turns out.
