With zero calories, erythritol makes the perfect alternative to sugar in almost any recipe—give it a try with these tempting lemon bars!

These fragrant lemon bars are wonderful eaten on the day they are made, to get the real zingy lemon hit. You can also experiment with other flavors—try them with lime juice and zest, grapefruit, blood orange, or even passionfruit. Recipe adapted from Baking Without Sugar by Sophie Mitchell.
