Keto Lemon Ice Box Pie Recipe

This pie is really sweet and creamy, so it’s perfect served frozen. Traditionally, lemon ice box pie has sweetened condensed milk for structure (and sweetness), but at 11g carbs per tablespoon, we are substituting with heavy whipping cream! For the lemon juice, I did not squeeze my own lemons. I used pre-squeezed juice, because it has less carbs than actual lemons. You can substitute the monk fruit sweetener for one of your choice, but be sure to reference a conversion chart. If you decide to experiment and change up the recipe, let me know what you tried, and how it turned out!
