Low Carb – Chocolate Rum Layer Cake

Here’s the recipe for the low-carb cake I made for JB’s birthday yesterday. One note… its yummy!! Make sure to give yourself a lot of time to prepare it. Even though making the cake doesn’t take that long, letting it cool, and the time needed for the toppings to set takes a few hours.
