There is no sugar added to this pie. The 1 gram you see is from the natural lactose in the heavy whipping cream and cream cheese.
PLEASE REMEMBER: While this pie is low carb and sugar free, it is not calorie free, it is not fat free. This is for a special occasion and not something I would indulge in but more than once a week. I must warn you, if you are trying to lose weight and this pie is in your fridge, you may have trouble with temptation. Take it to a friends house, enjoy a slice and leave it there, don't bring it home!
You can eliminate the chocolate drizzle and it will still be heavenly!
If you don't have nut allergies in the family you could swap the sunflower seeds with almonds or even use almond meal.
You can see I've not added any other sweeteners since the homemade caramel sauce is sweet enough on it's own. If you use another caramel sauce that is not my recipe you may need to reduce or adjust. Start with a smaller amount as you can always add more in the filling if needed.
