Rose cupcakes with blueberries in syrup

Work the butter at room temperature together with sugar until the mixture is light and foamy. Add the vanilla flavor and work some more. Add the eggs one by one and then the flour sifted with the self-rising flour. Add the milk and mix it with a palette knife. Finally, always with a palette or with a spoon, add the blueberries (well drained from the syrup) being careful not to crush them. Fill the molds, with a rose shape, and bake at 160 °C for 25 minutes. Finally, let cool completely, unmold and sift with powdered sugar.
