To prepare a spring fruits shortcake recipe, first preheat the oven to 350?F (180?C) and grease and flour two 9-inch springform pans. In another bowl, combine the flour, baking powder, sugar, cinnamon, and salt. Gradually add the wet ingredients to the dry ingredients, mixing just until combined. Pour the batter into the pan and bake for 20 to 25 minutes, or until the cake springs back when lightly touched. Let cool before serving.
