This Rhubarb Compote Cake is a delightful dessert that combines the tartness of rhubarb with the sweetness of cake. The rhubarb compote adds a burst of flavor and moisture to the cake, making it incredibly moist and tender. The cake is topped with a crumbly streusel topping, adding a nice crunch to each bite. Serve this cake warm with a scoop of vanilla ice cream for a perfect balance of flavors.
