Chocolate Peanut Butter Oatmeal Bars: Ingredients & Substitutions
As always, I recommend making this no bake chocolate oat bars recipe exactly as written, however here are a few possible substitutions.
- Salted Butter. unsalted butter, earth’s balance vegan butter, and ghee all are good substitutes.
- Light Brown Sugar. dark brown sugar and coconut sugar are good substitutions.
- Peanut Butter. Any nut or seed butter works well in this recipe – almond butter, cashew butter, sunflower seed butter, etc.
- Semi-sweet chocolate. Use chocolate chips, bars, or discs. The form doesn’t matter beacuse it is melted. Choose your favorite variety from milk to dark.
How to Make Chocolate Peanut Butter Oatmeal Bars

Something to note is that this recipe moves quickly. Lay out the ingredients, line the baking dish, grease a spatula, etc. before you begin.
Melt Chocolate and Peanut Butter
Begin this peanut butter oatmeal bars recipe by making the peanut butter and chocolate layer first. That way it has a little time to cool before the assembly phase.
Make the Oatmeal Layers
Next, make the oatmeal layers. This process goes quickly! Begin by melting the butter in a medium saucepan over medium heat.
Then stir in brown sugar and sea salt until the sugar is dissolved. Once it’s dissolved, turn the heat to low and add the vanilla and oats.
Cook the oatmeal mixture on low for about 2 minutes, or until the ingredients are combined.
Next, press about half of the oatmeal mixture into the bottom of the prepared baking dish with a greased spatula. (Reserve the other half to sprinkle on top).
Then, pour the chocolate peanut butter mixture gently and slowly over the bottom layer. Reserving about 2-3 tablespoons to drizzle on top.
Very gently crumble the remaining oat mixture over the chocolate peanut butter layer & press it into place. Drizzle the top with the remaining chocolate/peanut butter mixture.
Chill & Cut
Refrigerate the chocolate peanut butter oatmeal bars for at least 2 hours, or until the chocolate is set.
Once the chocolate is set, remove the peanut butter chocolate oat bars from the refrigerator and let them come to room temperature before cutting. This ensures straight lines and easy cutting. Cutting cold, hard chocolate is never easy.
Store/Freeze
Store the peanut butter chocolate oat bars in an airtight container at room temperature for up to 5 days, in the refrigerator for up to 1 week, or in the freezer for 2 months.
Chocolate Peanut Butter Oatmeal Bars FAQS

Yes. Chill the bars, then wrap them tightly in plastic wrap and store them in an airtight container in the freezer for up to 2 months. Thaw slowly at room temperature – do not microwave.
If your bars are crumbly, you may have over-cooked the butter mixture or added too many oats. Either decrease the intensity of heat next time or decrease the cooking time (or both).

I wouldn’t use coconut oil because it melts at room temperature. They would not hold up well
WOW! I made these for a work function, even did a double recipe, and they were kaput gone. I’ve had just about every person I work with asking for the recipe. These bars were awesome. Between these and some lemon bars I made as well I’ve undeservedly gained a reputation as a baking diva. Thanks so much for this AMAZING recipe. I will definitely refer everyone to your blog and continue making these for like every event ever.
These. Are. Amazing. I couldn’t use butter because I’m dairy free, so I need to figure out which fake butter works best. I used EarthBalance this time, but I think I’ll try something different next time. My issue is the crumbly oat bottom. For some reason it didn’t harden up well. Did that stop me from eating the whole pan in < 24 hours? Heck no! Flavor is unbelievable. I will be making these for EVERY event! Even if that event is just Friday night at home with my family grilling hot dogs 😀
This looks so amazing! I’m a peanut butter fan! Can I use coconut oil instead of butter?
I made these today and they taste super good. It was for a friend who just had a baby and is GF – one of my first times making something GF. Question…it was super crumbly. Do you know why? It was basically falling apart in my hands just a few minutes after I got it out of the fridge. What did I do wrong? Or is that the way they are?
I’ve made these about a dozen times now. They’re a huge hit with family, co-workers, etc. 5*
YAY! I’m so glad you love them Laura! they’re such an easy and yummy treat to feed a crowd!
the carb count is for all 16 pcs or 1/16 pc . you do not speciify
The nutrition information is for one serving (so 1/16 of the recipe)!
do you think these work with rolled oats as well? I usually only keep those at home
Do you use quick oats? Or regular oats?
As I’m making stirring the oats in i realized they are not quick oats. I am going to leave them on the stovetop a few minutes longer than the recipe states…I’ll keep you posted on the outcome!
Your Bars look like a very special treat! Thanks so much for sharing your awesome recipe with us at Full Plate Thursday! Hope you are having a wonderful week and hope to see you soon!
