This classic strawberry rhubarb cake recipe is a perfect combination of sweet and tangy flavors. The cake is made with a moist and fluffy vanilla cake base, topped with a layer of fresh strawberries and rhubarb, and finished with a crumbly streusel topping. The secret to this recipe is to use fresh, ripe strawberries and tart rhubarb to balance out the sweetness of the cake. Serve this cake warm with a dollop of whipped cream or vanilla ice cream for a delicious dessert.
