Rich, velvety, and completely melt-in-your-mouth, this Keto Chocolate Peanut Butter Fudge gives you deep, chocolatey indulgence with minimal net carbs and no sugar required!
A Quick Reality Check 💡
Viral posts frequently claim keto treats contain “one carb” and allow you to “eat as much as you like,” but a realistic look at nutrition keeps things on track:
Low Net Carbs: Using sugar-free chocolate chips, natural peanut butter, and butter keeps net carbs around 1g to 2g per square.
Calorie Density: Peanut butter and butter are rich in healthy fats and calories. While fantastic for keto, eating “as much as you like” still adds up quickly in total energy intake.

4. Slice into 16 squares and serve cold!
Chef’s Tips
Use Powdered Sweetener: Granulated sweetener can leave a grainy texture; powdered keto sweeteners melt smoothly into the warm fat.
Store in the Fridge: Because of the natural oils, keep the fudge stored in an airtight container in the refrigerator or freezer so it holds its shape.
