    Lemon desserts are my absolute favorite, as you can tell from the abundance of lemony treat recipes on my site.

    This was inspired by my Keto Lemon Supreme Tarts recipe on this site.

    Keto Lemon Supreme Tarts
    Keto Lemon Supreme Tarts are so sweet, tart, creamy, and refreshing with a buttery tart crust, a sweet whipped cream cheese layer, and a tangy sugar-free lemon curd layer.

    There is just something so very magical when you combine sweet and tart citrus flavors together. Lemon treats make my mouth incredibly happy.

        Hi Lisa, if you want gluten-free but not sugar-free then you can swap the sweeteners for regular powdered confectioners' sugar.
