In most cases, yes, sugar free chocolate is keto friendly.

My favorite sugar free and keto friendly chocolate is ChocZero – grab a ChocZero coupon here! (That said, for this recipe, you will probably use a brand like Lily’s chocolate because ChocZero does not currently make semi-sweet chocolate chips.)

    • Hi Jessica, That sounds like an amazing addition! 🙂 As for freezing, yes! You can freeze it for up to 2 months. To thaw, place it in the fridge for 24 hours before serving. The texture will change slightly upon thawing, but not too much. Enjoy!

    This Keto chocolate fudge is fantastic! It satisfies my need for chocolate and helps me stay Keto. It is so simple to make this recipe. After I cut the fudge into pieces, I separate it into groups of seven and freeze them in small freezer bags. Each week I can pull out a bag and since the fudge will keep in the refrigerator for a week, I have a chocolate low carb, sugar free treat waiting for me every day.

    Keto Fudge has moved to the top of my Keto sweets list! It is super easy to make and tastes wonderful. I love chocolate and this fudge keeps me Keto when I need a treat. My non-Keto boyfriend loves this fudge too.

    • Hi Dayna! I have not, but I bet adding some peanut butter would work! Peanut butter flour might make it a little grainy.

Welcome! I’m Jessica.
