No More Reese’s Peanut Butter Cups For Me

Do you know that before I made low carb keto a lifestyle, Reese’s Peanut Butter Cups were a regular part of my life? Fast forward almost four years, and a real Reese cup hasn’t crossed my lips.

This by no means that I suddenly stopped loving the combination of peanut butter and chocolate.  However, traditional chocolate and peanut butter bars no longer fit my lifestyle. So, a new healthier version needed to take it’s place.

I sure hope you will give these low carb peanut butter fudge bars a try.
