Toasted Almonds

Whipped Cream Frosting
- 1½ cups (360 ml) heavy whipping cream
- 3 tablespoons powdered sugar
- 1½ teaspoons vanilla extract
- 1½ teaspoons unflavored powdered gelatin (optional but required for stabilized whipped cream)

Instructions
- Prepare Italian Sponge Cake: Preheat the oven to 340ºF (170ºC). Butter an 8 or 9-inch springform cake pan and line it completely with parchment paper. Sieve the cake flour and set aside. Using a stand mixer with whisk attachment, beat the eggs at room temperature with sugar at maximum speed for about 15 minutes until a frothy and firm cream forms. Add vanilla and lemon extract in the last 1-2 minutes. Gently fold in the sifted flour in small amounts using a spatula to avoid deflating the batter. Pour the batter into the prepared pan.
- Bake Sponge Cake: Bake in the preheated oven for about 25 minutes without opening the door during the first 20 minutes. Check doneness by inserting a toothpick in the center; if it comes out dry, the cake is done. Turn off oven and leave the cake inside with door ajar for 5 minutes to prevent thermal shock. Remove cake from pan and cool completely on a rack.
- Make Crema Pasticcera (Italian Pastry Cream): Heat 2½ cups milk with lemon zest in a saucepan until steaming but not boiling. In a bowl, whisk egg yolks, sugar, and flour until smooth, then add remaining ½ cup milk. Remove zest from heated milk. Slowly whisk hot milk into egg yolk mixture, add vanilla extract, strain back into saucepan, and cook over medium heat while whisking constantly until thickened and boiling. Boil for 1 minute to cook flour. Divide cream into two bowls, stir chopped chocolate into one. Cover both with plastic wrap touching the surface to prevent skin formation. Refrigerate until chilled, then stir smooth before using.
- Prepare Rum Syrup: Combine water and sugar in a saucepan over medium heat until sugar dissolves. Remove from heat and cool. Stir in rum. Refrigerate if making ahead.
- Toast Almonds: Preheat oven to 350ºF (180ºC). Spread sliced almonds on a baking sheet and toast for 8-10 minutes or until lightly browned and fragrant. Cool before use.
- Make Whipped Cream Frosting: Chill mixer bowl and whisk. For stabilized cream, sprinkle gelatin over 6 teaspoons water and let sit 3-4 minutes, then microwave briefly to dissolve and cool slightly. Whip heavy cream with powdered sugar and vanilla until soft peaks form, then slowly add gelatin and whip to firm peaks. Use immediately or refrigerate briefly.
- Assemble and Decorate Cake: Slice sponge cake horizontally into three even layers. Place bottom layer on serving plate, spoon rum syrup to moisten. Spread vanilla pastry cream over it, then add second layer. Moisten second layer with rum syrup, spread chocolate pastry cream. Add final cake layer, press gently and moisten with remaining rum syrup. Chill if cake seems unstable. Spread ¾ of whipped cream frosting over cake top and sides. Press toasted almonds onto sides and pipe rosettes with remaining frosting on top edges. Decorate with maraschino cherries and chocolate flakes.
Notes
- Use room temperature eggs for better volume in sponge cake.
- Superfine or caster sugar dissolves better and creates finer crumb texture.
- Folding flour gently preserves air bubbles necessary for sponge rise.
- Do not open oven door during first 20 minutes to prevent cake collapse.
- Press plastic wrap onto pastry cream to prevent skin forming while chilling.
- Using gelatin in whipped cream stabilizes it for longer holding.
- The rum level can be adjusted according to flavor preference.
- Toasted almonds can be stored in an airtight container and reused.
