This delicious cake is a perfect combination of sweet strawberries and tangy rhubarb. The streusel topping adds a crunchy texture to the soft and moist cake. To make this cake, you will need flour, sugar, baking powder, salt, butter, eggs, vanilla extract, milk, fresh strawberries, and rhubarb. Mix the dry ingredients and then add the wet ingredients to make the batter. Fold in the chopped strawberries and rhubarb and pour the batter into a greased baking dish. Top with the streusel mixture made with flour, sugar, and butter. Bake for 45-50 minutes until golden brown. Serve warm with a dollop of whipped cream or vanilla ice cream.
