Retro-style – but updated, Chocolate Peanut Butter Oatmeal Bars. Think doughy, buttery oatmeal cookie base, layered with creamy peanut butter, and sweet salted chocolate on top. All made with simple, wholesome ingredients: oats, pure maple syrup, natural peanut butter, and dark chocolate. They’re sweet, salty, heavy on the peanut butter, extra chocolatey, gluten-free, and butter-free. Every last bite is truly delicious.

When I think of February, I think Super Bowl Sunday, and then of course, Valentine’s Day. This year, we have the Olympics which makes things even more exciting. I’m sharing a couple appetizer recipes next week that will be great for viewing your favorite winter sport as well as the upcoming Super Bowl too. Lots of fun things this month!

For some reason, when I think of the Super Bowl, I always think of chocolate and peanut butter together. I’m sure it’s because I’m from Cleveland. Ohio is the Buckeye State, which means we all love our chocolate/peanutty sweets.

These bars are one of my favorite chocolate-peanut buttter combos yet. They’re somewhat inspired by my lunchroom peanut butter bars. But also by the Twix bars I shared a couple weeks ago. I took elements from both and incorporated them into this recipe. 

What’s awesome is that they’re naturally gluten-free, butter-free, and have no added sugar other than pure maple syrup! We’re all loving the more wholesome desserts right now.

I based this layer off of my mom’s oatmeal cookies, but made things less sweet. Just some oats, almond flour, and maple syrup with eggs and vanilla. 

I also used coconut oil in place of vegetable oil, something I’ve been doing for years. 

Then, just bake the cookies until set. They taste buttery and perfectly sweet, but with no butter or sugar!

The peanut butter layer

Simply just peanut butter, maple syrup, and coconut oil boiled together to thicken the mix. The secret to making this layer really delicious is to use a peanut butter with just peanuts and salt. Don’t use a no-stir peanut butter that contains oils and/or sugar. You just want a natural peanut butter. This will give you the best flavor and texture.

Pour the peanut butter layer over the oatmeal cookies, then freeze the bars. You only need them to freeze them for 30 or so minutes. This helps the peanut butter set up quickly.

When the peanut butter is chilled and stiff, pour some melted chocolate overtop to finish the layers up. My one piece of advice here is to slice the bars before the chocolate top becomes too hard. This will make the bars much easier to cut and prevents the peanutty filling from getting squished out.

The final review? Slightly chewy and crumbly on the bottom, with the creamiest peanutty filling – that’s perfect salted. The chocolate top adds a nice “crack” with every bite. 

Delicious! And great for parties too since these can really feed a crowd!

Ingredients

Oatmeal Cookies

Peanut Butter Mix

Instructions

  • 1. Preheat the oven to 350° F. Line a 9×13 inch baking dish with parchment paper. 
    2. To make the cookies: In a mixing bowl, beat together the oats, almond flour, baking soda, salt, coconut oil, maple syrup, eggs, and vanilla. Press the dough into the prepared baking dish. Bake 25-30 minutes, until lightly golden.
    3. To make the peanut butter mix: In a medium pot, mix 1 cup peanut butter, the maple syrup, and coconut oil. Bring to a gentle boil over medium heat, stirring constantly. Cook 2 minutes, then remove from the heat. Pour over the oatmeal cookies. Freeze 30 minutes, until firm.
    4. Melt together the chocolate and 1/3 cup peanut butter in the microwave. Let cool 5 minutes and then spread the chocolate over the peanut butter mix. Return to the fridge to set, about 10 minutes, then slice. The chocolate will not be totally set, but slicing is easier this way. Keep in the fridge.

Notes

If the Cookie Dough is Dry: add 1/4 cup additional melted coconut oil to moisten it.

  1. in process of making. measurements in grams needed for novices like me. That would make it alot easier. I’m guessing everything. looking forward to tasting tho. can’t wait

    1. Hi Inez,
      Thanks for trying this recipe. If you just click “metric” under the list of ingredients, all of the measurements will convert for you. We have this feature for all of our recipes:) I hope this helps! xT

    I love how these aren’t super sweet. They were fun to make and who doesn’t love chocolate & PB. Great recipe Tieghan!

    1. Hi Kristen,
      Amazing! Love to hear that these were such a hit, thanks a lot for making them! Have a great Sunday! xT

    1. Hi Jules,
      Sure, you could use butter or another neutral oil in place of the coconut oil. I hope you love this recipe! xT

    1. Hi Lisa,
      You do not need to let the bar layer cool completely before adding the peanut butter:) I hope you love this recipe! xT

    Agree with Brooke’s comments. My cookie dough was very wet, so I didn’t think it needed more oil, but when I baked it, it became dry and crumbly. I haven’t worked with almond flour before so maybe that was it. Agree as well that the peanut butter layer should be thicker.

    1. Hi Lauren,
      Thanks for making this recipe and sharing your feedback!! Almond flour definitely gives much different texture than what you might be used to with all purpose flour. Thanks again for trying the recipe! xT

    I have never made a recipe of yours that didn’t turn out perfect, until this one. I was so bummed because this recipe calls for expensive ingredients. I didn’t make any alterations to your recipe either. The cookie base was very dry and crumbly, the peanut butter layer was too thin (not like the pictures at all), the the chocolate top was way too thick.

    I am going to make this again and add a little bit more coconut oil to the cookie part, double the PB layer, and cut the chocolate top in half. 🤞🏻 I’m hoping for a better turn out with take two.

    1. Hi Brooke,
      I appreciate you making so many recipes and sharing your feedback! I’m so sorry this one didn’t turn out great for you, let me know what happens when you try again! xT

    1. Hi Samantha,
      Yes, oat flour would also work for you! Let me know if you give this recipe a try, I hope it’s a hit! xT

    1. Hi Deanna,
      I would start with 1 1/2 cups and see how that goes, if the batter is too wet slowly add more as needed:) I hope this helps! xx

        Can I replace maple syrup with cane sugar in both the cookie and the PB? I liked the texture of the bars a lot but would prefer a sweeter dessert. Thanks!!

    1. Hi Kathryn,
      Happy Monday!! Thanks a lot for trying this recipe out and your feedback! Love to hear it turned out well! Yes, you can freeze these! xT

  5. Although these still taste delicious, the oatmeal cookie layer did fall apart when I cut it/eat it, like the other reviews reflect. The peanut butter layer was also not as thick as the pictures, which was also a little disappointing. I still give this 3 stars though because the flavor is great and I love half baked harvest 🙂

    I just made these yesterday, and they turned out fantastic! I did not have any issues with crumbling or the layers sticking together, as other comments have said. I followed the recipe exactly. Kids and hubby all love them as well!

        I’ve made this several times now. Such a delicious non processed treat! Just a lil piece totally satisfies my sweet tooth without all the junk. Thanks for a great recipe.

        1. Hey Karin,
          Happy Friday!! I appreciate you making this recipe so often and your feedback, so glad to hear it always turns out nicely for you! Xx
