Love chocolate and peanut butter? These no-bake Low Carb Chocolate Peanut Butter Bars make a perfect sweet treat without the sugar crash. They’re easy to make, packed with healthy ingredients, and require no baking!
The base combines natural peanut butter, raw honey, butter, vanilla, ground flaxseed, and unflavored protein powder. This mix creates a chewy, satisfying texture with plenty of protein, fiber, and healthy fats. Unlike traditional bars loaded with sugar, these use real, nutrient-dense ingredients that support a low carb lifestyle.
I used Vital Proteins Collagen Powder in this recipe to add a boost of protein and extra nutrition. It blends seamlessly into the peanut butter mixture, giving the bars a smooth texture without altering the flavor. Plus, collagen supports healthy skin, hair, joints, and digestion—an added bonus! I also used it to calculate the nutrition info, but you can easily swap in any unflavored protein powder. Whey, egg white, or plant-based protein should all work well, so feel free to use what you have on hand!
A smooth layer of low-carb chocolate tops these bars for a rich, indulgent finish. No need for fancy equipment—just mix, spread, chill, and enjoy! These bars are gluten-free, grain-free, and keto-friendly, making them a great choice for a healthy snack.
