    Chocolate Peanut Butter Oatmeal Bars

    Updated: Nov 17, 2024 | Published: Sep 18, 2018 | by Amanda | 26 Comments

    For the days you need something sweet and you need it fast, these chocolate peanut butter oatmeal bars can be prepared in around 10-minutes, have only 4-ingredients plus there's no-baking required.

    Breathe...the chocolate is on its way.

    I don't "get" people who don't get peanut butter. What's not to get? It's like oxygen but with peanuts in it. But I already married him so what are you gonna do? I will just have to eat all the peanut butter and apple oats jar myself. I'll survive. 

    If I were trendy I would call this the ultimate minimalist square. But I am not trendy, I am a forty-something author and food blogger living on top of a mountain. I sometimes wear socks with my vegan Birkenstocks. In public.

    However, the minimalist tag is very appropriate here. Four ingredients and no baking = pretty darn minimal. It the sweet version of my 3-ingredient zucchini soup but way less grown up.

    What You'll Need

    Peanut butter and oatmeal bar ingredients in a grid labelled.

    The ingredients for this sweet treat will most likely be living in your pantry. All you need is;

    • rolled oats
    • peanut butter
    • maple syrup
    • vegan chocolate

    You could make your own chocolate - the chocolate in my vanilla fudge chocolate eggs will do the trick -but if like me, you are impatient, store-bought chocolate is fine. It's more than fine. It's downright awesome.

    Another neat thing about this recipe is that if you can't do peanut butter, it works with almond butter too. Swap out the peanut butter for almond butter and add a teaspoon of vanilla extract. Presto, nut butter and chocolate squares.

    Whichever you use, these fantastically fuss-free squares are deliciously chewy, chocolatey and completely addictive. When life feels anything but minimal, these little guys are a simple reminder that less is usually so much more. Enjoy, x.

    Equipment

    • 8-inch square baking

    Ingredients 

    Peanut Butter Oat Slice

    • 1 ½ cups (135g) rolled oats gluten-free if required
    • 1 cup + 1 tablespoon (305g) smooth peanut butter
    • ½ cup (120g) maple syrup

    Chocolate Topping

    • 1 cup (approximately 150g) vegan chocolate buttons small
    • 3 tbsp (75g) smooth peanut butter

    Instructions

    For the Peanut Butter Oatmeal Bars

    • Line an 8x8 inch square tin with grease-proof paper. 
    • Add the peanut butter and maple syrup to a medium saucepan and stir together over medium heat until combined.
    • Add the rolled oats and stir through so the oats are completely coated and combined. 
    • Remove from the heat and transfer the mixture to the lined brownie tin and press down to get it as level as you can. Set aside.

    For the Chocolate Topping

    • In a microwave or over a double boiler, melt the vegan chocolate and peanut butter together, stirring occasionally to combine. Pour the melted chocolate over the oat mixture and use a spatula or the back of a spoon to level out. 
    • Allow the slice and chocolate to cool before popping it into the fridge for at least 30 minutes. Slice in to bars or squares to serve.

      Do these have to be stored in the refrigerator? I’m wanting to take them to a camping event.

        Hi Becca, they do prefer a cold store (it's only peanut butter and maple holding them together) but you could store them in a cooler bag for camping. They tend to get a little soft stored at room temperature. Have a great trip!

      Great recipe. I added some coconut to the oat mixture and a spoonful of coconut oil bc I was using natural peanut butter and it was perfect. Thanks! Ashley

      Made these without realising I had to melt the butter and maple syrup but they were still amazing. Tried other recipes which called for dedicated coconut and almond meal too so happy to find this cheaper and easier alternative. My partner loved them so much he ate 6 in one sitting and wouldve ate the whole tray if I let him. Amazing!

        Kirsty! You nearly made me spit out my tea when I read that. That's so funny - and totally something I would do -but I am so glad the slice works without having to melt the butter and maple syrup. I might try that next time! Thanks so much for taking the time to let me know - I really appreciate it. You've made my day. A, x.

          Hello and welcome Imogen. You can freeze these. Cool them completely and then freeze them in a sealed container (I also wrap mine) for up to 3 months. Thaw them in the fridge. 🙂

      I'm wondering what kind of peanut butter you used. I used Smucker's natural and I'm thinking you might have used something like Skippy or Jiff (not judging at all just thinking about the oil content)? I had a similar problem with dryness but I realized while I was mixing the oats in. I added 4 tablespoons of butter to smooth things along and I'm hoping (I haven't tried them yet) that did the trick. I also put in a little less oats than your recipe suggested. Thanks for putting the time into sharing your recipe!

        Hi Jennie - I am based in Australia so I use different brands but I absolutely think a softer peanut butter or one with more oil will coat the oats more readily and fully than a "healthier" peanut butter. I think it's great that you went with your gut and added more moisture to the mix. How did it go?! I hope it all worked out. A.

      The flavor is good, but mine came out very chewy and fell apart quite easily. Very messy to eat. I used an organic "Old Fashioned Rolled Oats" (longer cooking time). I wonder if this recipe should call for the quick cooking oats? Also my chocolate topping didn't "pour" out of the double boiler. These are good, but not what I was hoping for.

        Oh, Suzy. How disappointing. I have always used rolled oats with this recipe but perhaps not all oats are the same. Perhaps a little longer in the melted pot would help. I am away at the moment but when I get back I will try the recipe with the quick oats and see if it changes the texture. These squares are chewy but I've always found them to hold together easily - particularly after a trip to the fridge. With regards to the chocolate, it sounds like maybe the chocolate seized a little? It should melt and be totally pourable. I use Noble Choice Dairy-Free Chocolate Chips - it melts beautifully although it's not organic.
