Blend in desired amount of sweetener and lemon juice, to taste. The more lemon juice, the more it tastes like a cream cheese frosting. Add cinnamon, if using, and a pinch of salt.
Get your cake out of the freezer and spread this frosting over top. Let set up in the freezer or fridge if you want your frosting to harden slightly, or eat as is. Keep in the fridge.
YUM!! Enjoy! Try not to eat it all at once...
You'll need an immersion blender and high-speed blender (I use a Vitamix) or food processor.
*Feel free to adjust the flavors to your liking! Add in chopped raisins, walnuts, macadamia nuts, other spices like ginger or clove, or cashew butter rather than coconut butter for the frosting.
