Here's a quick and easy (Refined Sugar-Free) recipe for Hot Fudge Sauce!
1/2c Butter
3T Cocoa Powder
3/4c Coconut Milk
1c Coconut Sugar
1/3c Honey
Combine and bring to a simmer over medium heat - simmer for 7 minutes. Remove from stove then add 1/2t vanilla and blend for 1 minute in your blender - Yield 2 cups of Hot Fudge Sauce!
NOTE: be careful not to fill your blender over 1/2 way when blending hot stuff - the steam can make the lid pop off and make a painful mess - I have a vitamix with a steam releasing lid so I don't have to worry.
