Keto Chocolate Peanut Butter Bars Recipe | Wholesome Yum (2024)

If you’re a fan of the chocolate and peanut butter combo, these low carb keto chocolate peanut butter bars are for you! They are made up of 3 delicious layers: shortbread (based on my popular keto shortbread cookies), peanut butter, and chocolate. It’s sweet, crunchy, chocolatey, and SO good!

But don’t let the multiple layers intimidate you. They are all incredibly easy to make! You need just a few ingredients and several minutes for each one. These keto peanut butter chocolate bars will be ready to eat in just 30 minutes and you’ll be SO happy.

I actually created this recipe because I wanted to simplify my low carb tagalong cookies, because prior to these bars, that’s what my husband kept asking for. It got tiring to dip the cookies individually so often. The cookies may look more impressive, but when you want convenience, these keto peanut butter chocolate bars are the way to go.

I’m sharing my favorite keto peanut butter and chocolate recipes below, but if you love bars (they are a big thing here in Minnesota!), try out my low carb lemon bars, keto pumpkin bars, or keto pecan pie bars, too. And if you just crave peanut butter, make this easy keto peanut butter fudge!

I originally called them healthy peanut butter chocolate bars or gluten-free peanut butter bars – which they still are!

The latest version uses my favorite monk fruit sweetener and powdered monk fruit:

How To Make Keto Chocolate Peanut Butter Bars

These low carb peanut butter bars come together with 3 simple layers:

Shortbread Cookie Layer:

• Mix dry ingredients. Stir together Wholesome Yum Almond Flour and Besti Monk Fruit Allulose Blend.

• Mix wet ingredients. In a small bowl, stir together melted coconut oil and vanilla.

• Combine dry and wet ingredients. Pour wet ingredients into dry and mix together, until a crumbly dough forms.

• Add dough to pan. Press dough into the prepared pan – this is the perfect size.

• Bake. It’s done when the edges are golden.

Peanut Butter Layer:

• Mix dry ingredients. Stir together peanut flour and Besti Powdered Monk Fruit Allulose Blend.

• Add wet ingredients. Add peanut butter and vanilla into the bowl, and mix well.

TIP: Want less work? Use a food processor. It’s a bit more effort to do by hand, but that works, too.

• Add peanut butter layer to cookie layer. Dollop spoonfuls of the peanut butter layer over the cookie layer and spread it evenly.

Chocolate Layer:

• Melt chocolate. Mix sugar-free chocolate and coconut oil in a medium bowl. Heat in the microwave or over a double boiler until melted.

• Mix in sweetener. Whisk in Besti Powdered Monk Fruit Allulose Blend and let it dissolve.
• Top the bars. Drizzle chocolate over the peanut butter layer and smooth over the top evenly.

• Set. Cool completely, until the chocolate is solid. Then, carefully lift the parchment, transfer to a cutting board, and use a large chef’s knife to slice using a straight down motion.

TIP: Do not see-saw while slicing, or the bars will crumble.

Common Questions

Are peanut butter bars keto?

Regular peanut butter bars would not be keto, as they always have sugar added.

But these bars are keto friendly! Each serving has 3.7 grams net carbs.

Can you use a different sweetener?

Yes, you can. I prefer Besti Monk Fruit Allulose Blend in baked goods, as I think it provides the best flavor and texture, but you can use any granulated sweetener like allulosein the cookie layer and any powdered sweetener like Besti Powdered Monk Fruit Allulose Blendor powdered allulose in the peanut butter and chocolate layers.

If you have different sweeteners that you want to use, refer to my keto sweetener guide for more information on which sweeteners will work.

Can you make these no bake?

Yes, you can skip the cookie layer and you won’t need to bake these at all!

If you want no bake keto peanut butter bars without the shortbread layer, you’ll want to add a couple extra tablespoons of peanut flour to the peanut butter layer. That way, the bars will be more sturdy.

Storage Instructions

Can you make them ahead?

Yes, you can make these bars ahead. Because they need time to chill and solidify anyway, it’s a great make-ahead dessert or treat.

How to store keto peanut butter squares:

Store the bars in the refrigerator for up to a week… if they last that long! 🙂

Can you freeze keto peanut butter chocolate bars?

Yes, you can freeze the bars for 2-3 months. I recommend cutting them into individual servings before freezing, otherwise you’ll need to let the whole pan thaw a bit before you can cut into them.
