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.

    I love these cookies! I don’t find them too sweet & love all of these ingredients combined. They’re super easy & are perfect for dessert. Thanks so much Tieghan!

    I was a little disappointed. The base didn’t have much flavor. The best part was licking the bowl I melted the chocolate and pb in.

    1. Hi Kari,
      Thanks for giving the recipe a try and sharing your feedback, so sorry to hear it was not enjoyed! Please let me know if there is anyway that I can help! xx

    1. Hi Amy,
      I would recommend using maple syrup:) I hope you love this recipe, please let me know if you give it a try! xx

  3. Do you recommend letting the cookie layer cool before adding the peanut butter? I put it on straight out of the oven and I don’t know if that was correct

    1. Hey Kari,
      No need to let it cool, that is totally fine to put it on while warm! I hope you love the recipe! xx

    The topping was delicious, but like others- I found the base to be a bit dry, but then again they are a “healthier” version with no butter, so I may add a little next time- as the overall taste was great!

    1. Hey Meghan,
      Thanks so much for making this recipe and sharing your feedback! Hope you’re having a great week! xTieghan

    1. Hi David,
      Yes, that is correct:) You don’t have to use the exact chocolate that is linked, you can use any brand that you like:) Please let me know if you have any other questions, I hope you love the recipe! xTieghan

    The peanut butter didn’t really adhere to the cookie part and they were a little too crumbly, but taste was 10/10. Next time I’d let the cookies cool fully before adding the peanut butter layer and see if that makes a difference.

    1. Hey Kristen,
      Happy Monday! I love to hear that this recipe was enjoyed, thanks so much for making it and sharing your feedback!! Have the best week:) xx
