For a richer flavor, use brown butter in the crust. Simply melt the butter in a saucepan over medium heat, swirling occasionally, until it turns golden brown and smells nutty. Let it cool slightly before using. If your rhubarb is particularly tart, you may want to increase the sugar in the filling by a tablespoon or two. These bars are best enjoyed within 2-3 days of baking. Store them in an airtight container at room temperature or in the refrigerator.

Jun 30, 2025These bars were a hit! The gluten-free crust was surprisingly tender and the rhubarb filling was perfectly tart and sweet.
