Two sponge cake halves filled with cream and dipped in alchermes to resemble peaches are whimsical Italian confections. These playful mediterranean sweets are a family celebration favorite.
Preheat the oven to 350°F (175°C). Cream the unsalted butter with granulated sugar until light and fluffy, taking care not to overbeat as this impacts sponge structure.
Beat in the eggs one at a time, mixing thoroughly after each addition. Stir in the vanilla extract and lemon zest for a delicate flavor base.
In a separate bowl, combine all-purpose flour and baking powder. Alternate adding dry ingredients and milk to the wet mixture, mixing on low speed just until incorporated.
Scoop rounded balls (about 1 tbsp each) onto a parchment-lined baking sheet, ensuring spacing for even baking. Bake for 15–18 minutes until just lightly golden; avoid overbaking for proper moisture.
While cakes cool, prepare the filling by blending ricotta and heavy cream until smooth. Once cool, gently hollow flat sides of each cake ball.
Pair cakes into halves, fill the center with the ricotta mixture, and press to seal. Dip each assembled 'peach' gently in alchermes, making sure not to soak excessively.
Roll immediately in sugar for the signature crystalline finish. Let set for at least 30 minutes before serving to allow flavors to meld and shells to hold structure.
