Yield: 8 generous servings
Preparation time: 1 hour plus chilling
Baking time: 25 minutes



3/4 cup / 180ml whole milk
2 3/4 Tbsp cornstarch
1 large egg, beaten
9 egg yolks, beaten
3 3/4 cups / 900ml heavy whipping cream
1/2 vanilla bean OR 1/2 tsp vanilla extract
1/2 cup + 1 tablespoon / 115g granulated sugar

Chiffon Cake

1 1/2 cups / 190g cake flour
3/4 cup / 165g superfine sugar
1 1/3 tsp baking powder
1/3 tsp salt
1/3 cup / 80ml canola oil
1/3 cup / 80ml beaten egg yolks (3 to 4 yolks)
3/4 cup / 180ml fresh orange juice
1 1/2 Tbsp grated orange zest
1 tsp pure vanilla extract
1 cup / 240ml egg whites (about 8 large)
1 tsp cream of tartar

Chocolate Glaze

Note: The chocolate glaze recipe makes a lot, so make as much or as little glaze as you would like. Scaling this is straightforward since it’s 1 part chocolate to 1 part butter.

8 oz / 225g semi or bittersweet chocolate
8 oz / 225g unsalted butter


To prepare the custard

Combine the milk and cornstarch in a bowl; blend until smooth. Whisk in the whole egg and yolks, beating until smooth. Combine the cream, vanilla bean and sugar in a saucepan and carefully bring to a boil. When the mixture just boils, whisk a ladleful into the egg mixture to temper it, then whisk this back into the cream mixture. Cook, stirring constantly, until the mixture is thick enough to coat the back of a spoon. Strain the custard and pour into 8 large custard cups. Refrigerate to chill.

To prepare the chiffon cakes

Preheat the oven to 325°F / 160°C / Gas Mark 3. Spray 8 molds with nonstick cooking spray. You may use 7- ounce custard cups, ovenproof wide mugs or even large foil cups. Whatever you use should be the same size as the custard cups.

Sift the cake flour, sugar, baking powder and salt into a large bowl. Add the oil, egg yolks, orange juice, zest and vanilla. Stir until smooth, but do not overbeat.

Beat the egg whites until frothy. Add the cream of tartar and beat until soft peaks form.

Gently fold the beaten whites into the orange batter. Fill the sprayed molds nearly to the top with the batter.

Bake approximately 25 minutes, until the cakes bounce back when lightly pressed with your fingertip. Do not overbake. Remove from the oven and let cool on a wire rack. When completely cool, remove the cakes from the molds. Cover the cakes to keep them moist.

To prepare the glaze

Chop the chocolate into small pieces. Place the butter in a saucepan and heat until it is just about to bubble. Remove from the heat; add the chocolate and stir to melt. Pour through a strainer and keep warm.

To assemble

Cut a thin slice from the top of each cake to create a flat surface. Place a cake flat-side down on top of each custard. Cover the tops with warm chocolate glaze. Serve immediately.
