I saw a video of an amazing dessert on Facebook the other day and thought - how can I make this a low carb, and still decadent treat... After making my changes and adding my own touches, I came up with this dessert. It would be perfect for date night, Valentines, birthdays, or any special occasion. It is an amazing dessert with the rich flavors of dark chocolate and coffee - and it only has 5 net carbs per serving!!! I know it has a few steps, but it is very easy, and well worth the time. Enjoy (:
