This recipe for strawberry rhubarb cake is a simple and delicious way to enjoy the classic combination of sweet strawberries and tart rhubarb. The cake is moist and tender, with a crunchy streusel topping that adds a nice texture contrast. To make the cake, you'll need flour, sugar, baking powder, salt, butter, eggs, milk, vanilla extract, fresh strawberries, and fresh rhubarb. The streusel topping is made with flour, brown sugar, cinnamon, and butter. Simply mix the dry ingredients together, then add the wet ingredients and mix until smooth. Fold in the chopped strawberries and rhubarb, then pour the batter into a greased baking dish. Sprinkle the streusel topping over the batter, then bake in a preheated oven for 45-50 minutes, or until a toothpick inserted into the center of the cake comes out clean. Serve warm or at room temperature, with a dollop of whipped cream or a scoop of vanilla ice cream.
