Notes

 
Net Carbs: 4g
  • You can certainly change out the sweetener to your choice.
  • If you want a less crumbly crust, add a few tablespoons more of butter or even coconut oil to the crust mixture in the food processor and process until desired.
  • If you don't have erythritol for the crust just eliminate and use 2 tablespoons of powdered stevia or even coconut sugar.
  • FUN FACT: Key limes are not actually green when ripe as the limes you see in most supermarkets. In fact they are yellow when ripe. They are more tart and bitter than typical limes. They are well known in the Florida Keys as the "key" ingredient in making Key Lime pie. But obviously if you can't find "true" key limes, regular limes will also work.
  • FYI: Absolutely NO avocado flavor is present in this pie, it simply makes the filling super duper creamy!
