Instructions

Bake the Sponge Cake
Preheat oven to 350°F. Grease a 9-inch round cake pan and line the bottom with parchment.
Beat eggs and sugar until light and fluffy (about 7–8 minutes). Sift together flour, cornstarch, baking powder, and salt. Gently fold into egg mixture.
Pour into pan and bake for 25–30 minutes. Let cool completely. -
Make the Custard
In a saucepan, whisk milk, egg yolks, cornstarch, and sugar over medium heat until thickened.
Remove from heat, stir in vanilla, and cover with plastic wrap (touching the surface). Chill. -
Whip the Cream (with Gelatin Magic)
Sprinkle gelatin over cold water and let bloom 5 minutes. Gently heat to dissolve.
Beat cream with powdered sugar and vanilla to soft peaks. Slowly add gelatin while whipping to stiff peaks. Chill. -
Color and Roll Marzipan
Knead green food coloring into marzipan. Roll into a 12-inch circle on a powdered sugar-dusted surface, adding a little clear extract to prevent sticking. -
Assemble the Cake
Slice sponge into 3 even layers.
Place bottom layer on a cake stand, spread with jam and half the custard.
Add middle layer, then top with remaining custard and a dome of whipped cream.
Place final sponge layer on top and gently press to shape. Cover entire cake with whipped cream, smoothing into a dome. -
Finish with Marzipan & Roses
Drape marzipan over the cake, smoothing gently and trimming excess.
Dust with powdered sugar and top with a rose or two. Ta-da!
Notes
- Chill your bowl and beaters for better whipped cream results.
- No marzipan? Fondant will work in a pinch, but marzipan adds that authentic almond sweetness.
- You can prep the sponge and custard a day ahead—just assemble the morning you serve.
