These muffins combine tart rhubarb and silky custard with a buttery crumb topping for a cozy, comforting treat perfect for breakfast or snacks.
Keep crumb topping cold until baking to maintain crunch. Do not overmix batter to avoid tough muffins. Toss rhubarb in a tablespoon of flour if very juicy to prevent soggy muffins. Tent with foil if muffins brown too quickly.
