A moist and fragrant upside down cake featuring fresh rhubarb and a unique cardamom syrup, perfect for spring baking and gatherings.
Cream butter and sugar properly to trap air for a tender crumb. Do not overmix batter to avoid dense cake. Cook rhubarb topping gently to keep stalks firm but soft. Let cake cool 10 minutes before inverting to prevent sticking. Drizzle cardamom syrup after baking for extra moisture and flavor. For gluten-free, use gluten-free flour blend with xanthan gum. For vegan, substitute butter with coconut oil, eggs with flax eggs, and milk with almond or oat milk.
