How To Make Chocolate Peanut Butter Oatmeal Bars
This is the easiest no-bake bar you will either make. The base and topping use the exact same mixture to reduce the effort in the kitchen.
Plus the middle layer is a simple combination of two ingredients.
So let me share with you my tips to make this easy dessert in no time.
All you need to make these delicious, decadent chocolate oat bars with peanut butter are:
- Quick Oats – I don’t recommend rolled oats simply because their texture is coarse and the layer doesn’t firm up the same.
- Coconut Oil or plant-based butter – I recommend refined coconut oil if you don’t like the light coconut flavor that contains extra virgin coconut oil.
- Sea Salt
- Coconut Sugar or unrefined cane sugar, or simply any sugar you have on hand. I do have a preference for unrefined sweeteners, but brown sugar and white sugar also work well.
- Vanilla Extract
- Maple Syrup or any liquid sweetener you love, like agave syrup or coconut nectar.
For the chocolate peanut butter mixture you need:
- Dark Chocolate or semi-sweet chocolate chips – I do like 70% cocoa to keep the sugar low and enhance the chocolate flavor of the bars.
- Peanut Butter – Pick natural peanut butter with no added sugar and no added oil.
Preparing The Oatmeal Mixture
As mentioned earlier, the oatmeal mixture is used to make the base and topping of the chocolate peanut butter bars.
In a large mixing bowl, add quick oats and salt. Stir to combine and set aside at room temperature.
In a non-stick saucepan, add coconut oil, maple syrup, and coconut sugar.
Bring the saucepan over medium heat, stir constantly until the sugar is fully melted and the mixture is warm and bubbly.
Pour the liquids onto the oat mixture and using a silicone spatula, or the paddle attachment of your stand mixer, stir all the ingredient together.
The oatmeal mixture should be slightly wet but sticky, and if not, if too dry, simply add a splash of water. It should hold together if you squeeze the batter in your hands.
Line an 8-inch x 8-inch square pan with parchment paper. Lightly grease the paper with cooking oil spray.
Add some of the oat mixture to cover the bottom of the pan evenly, but keep about 1/2 cup aside in the bowl for the topping of the bar.
Press the batter firmly onto the baking dish, using the back of a spoon or a silicone spatula to spread an even layer of oats.
Preparing The Chocolate Filling
Set aside the base in the fridge while making the filling.
In a microwave-safe bowl, or non-stick saucepan add chocolate chips and peanut butter.
Stir and cook over medium heat until the chocolate is completely melted and combined with the peanut butter into a thick and shiny chocolate mixture.
If you are using a microwave, microwave in 30-second bursts to avoid burning the chocolate and stir after each time. Stop when fully melted.
Assembling The Peanut Butter Oat Bars
Remove the bar from the fridge and pour the warm chocolate layer all over the oat base.
Sprinkle the remaining oatmeal mixture all over the bar.
There are two options to set this no-bake dessert.
First, you can refrigerate the dessert overnight to set the layers over time.
For a quicker dessert, pop the bar in the freezer for 15 minutes. The bar is ready when the chocolate peanut butter filling is thick, not liquid and the toppings is hard.
Slicing The Bars
Use a long sharp knife to easily slice this peanut butter oatmeal bar recipe. Warm the knife blade over a flame, or warm water.
Dry the blade, then slice the bar into 16 squares. The warmth of the blade makes it easier to cut through the chocolate and oat layers without breaking the layers into crumbly pieces.
Store the bars in an airtight container in the fridge for up to 2 weeks. You can also freeze the bars in zip-lock bags or airtight containers for up to one month.
Thaw in the fridge the day before serving.
You can serve the bars at room temperature. They won’t melt that easily, except if you place them in a hot sunny place.
Serve plain or with a drizzle of extra melted dark chocolate, peanut butter or shredded coconut.
Here are some options to make this oatmeal bar if you have some allergies to the ingredients used in this recipe:
- Nut-Free – You can swap peanut butter for sunflower seed butter, pumpkin seed butter, or tahini.
- Sugar-Free – You can use sugar-free liquid sweeteners and allulose instead of coconut sugar. Also, use a sugar-free stevia-sweetened chocolate chip brand.
- Gluten-Free – Pick gluten-free certified oats.
