FOR THE SPONGE CAKE
- 5 eggs
- 1 cup granulated sugar
- 2 teaspoons baking powder
- 2 1/2 cups flour
FOR THE PASTRY CREAM FILLING
- 3/4 cup milk
- 3/4 cup cream (whole or whipping cream)
- peel one orange (try not to get the white part)
- 4 large egg yolks
- 1/2 cup granulated sugar
- 1/2 teaspoon vanilla
- 2 1/2 tablespoons all-purpose flour
- 2 tablespoons fresh orange juice
- 2 rolls puff pastry
- 1/4 cup powdered / icing sugar (more or less)
- 1/2 cup water
- 1/4 cup granulated sugar
- 2 tablespoons orange juice (or Grand Marnier)
- 1 cup cream (whole or whipping cream)
- 1/4 cup powdered / icing sugar (sifted)
- 1/2 - 3/4 cup chopped almonds
While the cake is baking make the Pastry Cream Filling. In a medium pot, add the milk, cream and orange peel and heat to very hot over medium heat, do not boil. Remove from heat and let cool to warm. Remove the peel and discard. In a medium pot add yolks and sugar, whisk together until combined, then add the vanilla and flour and combine. Place the pot over medium / low heat, add warm milk/cream, whisking continuously until almost thickened then add the orange juice and continue until thick. Remove to a glass bowl, cover with plastic wrap (make sure wrap touches the cream mixture) and refrigerate at least 1.5 hours.
While the cake is cooling and the Pastry Cream is chilling. Prepare the puff pastry. Roll out the pastry and gently roll a couple of times with a rolling-pin. Cut the puff pastry a little larger than the 9 inch cake pan. Place on a parchment paper lined cookie sheet, prick the dough with a fork (see photo). Sprinkle with powdered / icing sugar and bake for approximately 15-20 minutes or until golden. Let cool completely.
In a medium pot on medium heat, add the water, sugar and juice, heat until boiling then reduce heat and simmer for 5-7 minutes. Remove to a small bowl and let cool completely.
PUTTING THE CAKE TOGETHER
On a flat plate place one teaspoon of pastry cream then place 1 puff pastry round on top (this keeps the cake from slipping), top with 1/4 of the cream filling, place the sponge cake layer on top and top with almost all of the orange syrup, then top with 1/4 of the cream filling, place the remaining puff pastry layer on top (at this point I found it best to refrigerate the cake for 30 minutes). Then finish frosting the cake and sides with the remaining cream filling. Sprinkle with ground almonds. Refrigerate cake for at least one hour before serving. Enjoy!
