This Strawberry Rhubarb Sheet Cake is a quick and easy dessert that is perfect for feeding a crowd. The cake is moist and tender, with a sweet and tangy filling of fresh strawberries and rhubarb. The cream cheese frosting adds a nice sweetness and tanginess to the cake. To make the cake, simply mix together the dry ingredients, cream the butter and sugar, and then add the eggs and vanilla. Pour the batter into a greased baking sheet, top with the fruit filling, and bake for 25-30 minutes. Once the cake is done, let it cool before spreading the cream cheese frosting over the top.
