How to Make Chocolate Peanut Butter Bars

  • Prepare the pan: Spray an 8×8 pan with non-stick spray and line with parchment paper or foil. Set aside. 
  • Combine the wet ingredients: In a medium saucepan heat 2 cups peanut butter and maple syrup over medium heat, stirring constantly until fully combined and smooth. 
  • Make the chocolate topping: In a small saucepan heat the chocolate and the rest of the peanut butter over low heat until fully melted and combined. Mix in the oats: Add the ground oats and stir until fully combined. The mixture will be thick.
  • Add it to the pan: Press the mixture evenly into the prepared pan. Set aside.
  • Spread the melted chocolate mixture over the oat mixture and spread evenly.
  • Refrigerate the bars: Place the bars in the fridge until fully set, about 1 hour.
  • Enjoy: Cut into 16 equal-sized bars.

Tips and Notes

  • Be sure to line your pan as it’s much easier to remove the bars once ready. Simply lift out the entire parchment paper.
  • Since it takes time for the chocolate peanut butter bars to set in the fridge, I suggest you plan to make these ahead of time.
  • If you don’t have maple syrup, honey or agave would work in this recipe as well. 

Chocolate Peanut Butter Bars FAQs

Can you freeze these?

Yes! You can freeze these peanut butter bars! Cover bars tightly (cut or uncut) and transfer to the fridge. Once ready to enjoy, thaw them overnight in the fridge beforehand. I prefer to freeze them cut up so I can thaw one or two chocolate peanut butter bars out for myself whenever I’m craving it.

How long do leftovers last?

You can store these chocolate peanut butter bars for up to 7 days in an airtight container in the fridge.

How can I make clean slices?

If you want pretty clean slices for these peanut butter bars, simply run your knife under hot water between cuts. 

Can I use a different peanut butter?

The bars are meant to have a smooth filling. If you use chunky peanut butter, your filling will be chunky. If that’s what you would like, you can totally use a different peanut butter. Just keep in mind that yours won’t be smooth and creamy.

Can I melt the ingredients in the microwave? 

I prefer combining my ingredients on the stovetop as the heat is distributed more evenly and I can stir it as it heats up. If you’re going to use the microwave, you’ll have to heat it up in short bursts and keep a close eye on it.
