Xanthan Gum Free Grain-Free Lemon Bars
Bright, tangy, and silky-smooth, these lemon bars deliver everything you love about the classic dessert without a grain or a gum in sight. The crust comes together with almond flour, coconut oil, and honey — no fillers, no stabilizers — and bakes up golden and compact with just the right amount of buttery richness. The filling gets its luscious, sliceable texture entirely from arrowroot starch and eggs, so there's no need for xanthan gum or any of the synthetic binders that sneak into so many gluten-free baked goods. Fresh lemon juice and zest from real lemons give the custard layer a sharp, sunny brightness that balances beautifully against the sweet, nutty crust. Straining the filling through a fine-mesh sieve before it hits the pan is a small step that makes a big difference — you get a perfectly smooth, glossy top that sets up clean and cuts like a dream after a proper chill. A light dusting of powdered sugar right before serving makes them look like something from a bakery case, even though the whole process is genuinely straightforward. These are the kind of bars you bring to a gathering and watch disappear before you've even set down the plate.
