Keto Peanut Butter Bars are an easy, no-bake dessert that has all the flavour of a nutty, chewy candy bar! They are made with a combination of natural peanut butter, almond flour or coconut flour, butter, and a keto-friendly sweetener, such as erythritol or monk fruit. After being pressed into a pan, the base is spread with a silky layer of melted chocolate, making these a two-layer, rich dessert.
Loaded with healthy fats and moderate in protein, these bars are a perfect snack or dessert for any low-carb keto diet. They come together in a snap, don’t involve turning on the oven (a must in these sweltering months), and can be stashed in the fridge or freezer for a grab-and-go indulgence at any time.

It tastes like a traditional peanut butter chocolate treat, but contains no sugar, so that anyone on a low-carb diet can enjoy it freely. Variations involve a layer of shredded coconut, crushed nuts, or even cream cheese for more richness.
Great for holidays, parties, or on-the-go snacking, these bars are crowd-pleasers and convenient. But with their mix of nutty, chocolatey, and creamy, they are proof that keto desserts can be just as indulgent as their carb-laden counterparts.
