What Type of Sweetener is Best for Low Carb – Keto Lemon Bars?
I have used Truvia, Swerve, Erythritol, and monk fruit in this recipe. Pick what is best for your sweet tooth.
All of the options I mentioned have a low or zero glycemic impact on glucose levels.
Ironically, when I share altered recipes no one notices that I didn’t use granulated sugar or wheat in the recipe!
If you are new to lowering your sugar intake, then I suggest first trying the Truvia cane sugar blend, which contains some sugar with stevia and erythritol.
What Can I Use In Place of Coconut Oil?
I have used coconut oil in the crust as well as butter. You can also experiment with other cooking oils like vegetable oil.
The Crust For These Lemon Bars is Runny. What Happened?
The crust should firm up after about five minutes of mixing the ingredients for the crust. The coconut flour will absorb some of the moisture.
To troubleshoot, some readers have told me they put the crust in the refrigerator for about 10 minutes and it firms up.
You can also add a sprinkle of more coconut flour but don’t go overboard otherwise you will have a hard crust.
