These rhubarb crumble bars feature a buttery, crunchy crust, a tangy rhubarb filling, and a silky white chocolate drizzle, creating a perfect balance of sweet and tart in a quick and easy dessert.
Keep butter cold to ensure a crumbly crust. Use cornstarch to prevent soggy filling. Melt white chocolate in short bursts and stir frequently to avoid burning. Cool bars completely before slicing to keep them intact. For gluten-free, substitute flour with gluten-free blend; for dairy-free, use coconut oil and coconut cream. Add berries for a fruity twist or spices like ginger or nutmeg for warmth.
