This sheet cake is perfect for a potluck or a picnic. The combination of sweet strawberries and tangy rhubarb makes for a delicious and refreshing 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 sheet. Bake for 30-35 minutes until golden brown. Let it cool for a few minutes before serving. This cake is delicious on its own, but you can also serve it with a dusting of powdered sugar or a scoop of vanilla ice cream.
