Why You’ll Love Them

They’re delicious. If you love chocolate and peanut butter, this combination is hard to resist. They taste like Reese’s peanut butter cups, without the processed sugar.

They are easy to prepare. All you need is 6 simple ingredients! Each layer can be stirred together in less than 5 minutes. The hardest part is waiting for these no bake chocolate peanut butter bars to firm up so you can eat them.

They are perfect for special diets. If you need a gluten-free, egg-free, or dairy-free option, these are for you! You can also swap the peanut butter for almond butter or sunflower seed butter, if you prefer.

They’re easy to customize. If you want to use a different topping, such as melted semi-sweet chocolate chips, or you prefer a graham cracker crust, feel free to modify this recipe as you like!

They are naturally sweet. Instead of using powdered sugar, the chocolate and peanut butter layers are sweetened with pure maple syrup. (This is not to be confused with a processed pancake syrup, which won’t give you the same results.)

Ingredients You’ll Need

The coconut oil acts as a binder in this recipe, because it is solid when chilled. It’s what will give these bars structure, but if you don’t care for a coconut flavor, use refined or expeller pressed coconut oil, which has zero coconut taste. Or, you can use regular butter, if you don’t need a dairy-free recipe.

Almond flour offers a gluten-free option that you don’t need to bake, but feel free to experiment with other options, if you don’t mind a little trial and error. If you’re not a peanut butter fan, you can also use almond butter, tahini, or sunflower seed butter for another variation.

How to Make Chocolate Peanut Butter Bars

1. Make the chocolate crust.

In a medium bowl, stir together the almond meal, cocoa powder, maple syrup, and coconut oil until a thick, uniform mixture is formed.

Line a 9-by-5-inch loaf pan (or similar size baking pan) with parchment paper, then press the crust evenly into the bottom of the pan. Place it in the freezer to set while you make the next layer.

2. Make the peanut butter filling.

In the same bowl, stir together the peanut butter, maple syrup, coconut oil, and a pinch of salt.

Remove the chocolate crust from the freezer and spread the peanut butter mixture over the crust evenly, smoothing the top with a spatula. Return it to the freezer while you make the last layer.

3. Make the chocolate topping.

In the same mixing bowl, combine the coconut oil, cacao powder, and maple syrup. Make sure the maple syrup is at room temperature, otherwise it may cause the mixture to thicken. (This can also happen in a cold kitchen, which happened while I was taking photos!)

Remove the loaf pan from the freezer, and spread the chocolate on top of the peanut butter layer. Return the pan to the freezer and let the bars set until they are firm, at least 1 hour.

4. Slice & enjoy!

When the peanut butter chocolate bars are frozen, use the parchment paper to remove them from the pan. Use a sharp knife to slice the bars into squares, and then they are ready to eat.

These bars will soften and melt if you leave them at room temperature for too long, so be sure to store them in an airtight container and keep them chilled in the fridge or freezer. They should be served chilled for the best texture. (They are softer from the fridge, and firmer from the freezer– you can pick the texture you prefer!)

Chocolate peanut butter bars will keep well in the fridge for up to 2 weeks, or you can freeze them for up to 3 months.

Frequently Asked Questions

What can I use instead of coconut oil?

Unsalted butter would be the most similar replacement, but if you need a dairy-free recipe, try using your favorite vegan butter, instead. The fat you use needs to be solid when chilled. If you’re trying to avoid a coconut flavor, use a highly refined coconut oil, instead.

How do you melt coconut oil?

I usually spoon the solid coconut oil into an oven-safe measuring cup, and place it in a warm oven to melt briefly while I measure everything else. However, you can also place it in a microwave-safe bowl and use the microwave to melt it in 30 second intervals, or melt it in a pan on the stove top.

Can I use a different flour for the crust?

I haven’t tested this recipe with a different flour yet, but you might be able to use another ground nut with similar results. Or check out my oat flour pie crust, if you want to try using that as a base, instead. (You could probably use half of that recipe.)

Can I use a different size pan?

Of course! If you don’t mind a thinner bar, you can use an 8-inch square pan. Or, you can double the recipe if you’d like the layers to remain thick.
