Chocolate. Peanut Butter. Oat. Bars. Yep, we just did that. Or, um, we’re gonna do that!

Today’s perfect combo of chocolate, peanut butter and oats come together beautifully in our beautifully imperfect world for the yummiest, most soul-satisfying bars you’ve ever had.

And… did I mention? These chocolate peanut butter oat bars are:

  • No Bake
  • Easy to Make
  • Chockfull of guilt-free ingredients
  • Vegan, Dairy-Free
  • Most importantly… oh-so-GOOD.

Think: the most delicious mix of oatmeal cookie dough and peanut butter cups, all in one yummy bar.

You ready to no bake your way to desert success? (Oh dip, I meant dessert success.)

Let’s no bake this!

How to Make Chocolate Peanut Butter Oat Bars

Grab an 8-inch pan and some parchment paper. We’re gonna line the pan with parchment paper and set it aside for later.

Now, throw all of the wet ingredients into a large mixing bowl. Whisk it all together until smooth.

Add each dry ingredient to that same bowl (one-bowl, woohoo!). Grab a spatula or wooden spoon and stir all the wet & dry ingredients together until you form a dough. Fold in your add-ins (think chocolate chips and peanuts).

Pour your no bake oat bar dough into that pan you prepped earlier, then smooth it all into an even layer.

Melt the chocolate and pour it over the oat bar layer.

Freeze the bars for about 30 minutes, then slice and enjoy!

Tips!

  • Make sure to use creamy, drippy natural peanut butter: I’ve only tested these peanut butter oat bars with natural pb, so if you use regular JIF-style peanut butter, it might be a bit too thick.
  • Use your favorite chocolate: I love using my very favorite chocolate to make these bars because the flavor is so prominent. It doesn’t matter how much the chocolate costs, just how much you love it. 😉
  • Skip the chopped peanuts if you prefer peanut butter over peanuts. You can sub the chopped peanuts for more chocolate chips!
  • To get clean cuts: carefully use a super sharp knife. Here’s a fancy one that I love and an affordable one—they’re both great for everyday use to get clean cuts in your oat bars.

Storing and Freezing

Go ahead and pop these chocolate peanut butter oat bars into the fridge after making them. They’ll need just 1 day for the chocolate topping to set before you can safely store them at room temp.

From Day 2 and on, you can leave them at room temperature or in the fridge for about 1-2 weeks. Feel free to freeze them for up to 1 month as well. 😉

Soft ‘n chewy no bake chocolate peanut butter oatmeal bars that are easy to make & taste like chocolate pb cookie dough!

    These are a winner for us. But how on earth did you get your chocolate to look so perfectly straight and even?

      That’s so awesome to hear, Nicola! Chocolate: I just tap the heck out of that pan until air bubbles burst and the top smooths out. I should note that there are some swirls if you look closely. 😉 Sometimes though, I’ll just make exaggerated swirls instead of the painstaking even top because it’s just more fun that way! 😉

    These look like the perfect dessert for a small birthday party I am having for my husband. How far in advance do you think I can make those and they would still taste fresh?
