Instructions
Heat Milk for Custard
In a saucepan, combine 500 g milk, 1 tsp vanilla extract, and a pinch of salt. Heat over medium heat until just beginning to simmer.
Time: PT5M
Whisk Egg Mixture
In a separate bowl, whisk together 2 eggs and 160 g granulated sugar until well combined, then add 40 g cornstarch and whisk until smooth.
Time: PT3M
Temper Eggs
When the milk is simmering, remove from heat. Slowly pour the hot milk into the egg mixture in a thin stream while whisking constantly to prevent the eggs from scrambling.
Time: PT2M
Cook Custard
Return the combined mixture to the saucepan and place over medium heat. Stir continuously for 7‑10 minutes until the custard thickens, shows small bubbles, and becomes silky.
Time: PT10M
Cool Custard
Transfer the custard to a clean bowl, cover the surface with plastic wrap directly on the custard to prevent a skin, and let it cool to room temperature, then chill briefly in the refrigerator.
Time: PT30M
Heat Liquid for Choux Dough
In a clean saucepan, combine 70 g milk, 70 g water, and 60 g butter. Heat over medium heat until the butter melts and the mixture is hot.
Time: PT5M
Add Flour and Cook Dough
Add 1/4 tsp salt and 1/4 tsp sugar, stir, then sift in 100 g all‑purpose flour. Stir quickly; when the dough pulls away from the pan sides and looks glossy, continue cooking for another 1‑2 minutes to evaporate excess moisture.
Time: PT4M
Incorporate Eggs
Let the dough cool a couple of minutes, then add three room‑temperature eggs one at a time, mixing thoroughly after each addition until fully incorporated. The dough should become thick, glossy, and fall off the spoon in a smooth ribbon.
Time: PT5M
Portion and Shape Dough
Divide the dough into two equal portions. Line two 8.5‑inch cake rings with parchment paper and foil. Spread each portion into its ring, leaving a slightly uneven surface.
Time: PT5M
Bake Choux Layers
Place the rings on a baking sheet and bake in a pre‑heated 375°F oven for 15‑25 minutes, until puffed and deep golden brown.
Time: PT20M
Temperature: 375°F
Cool Pastry Layers
Remove from oven, let the layers cool completely in the rings before gently releasing them.
Time: PT30M
Beat Butter for Cream
In a mixing bowl, beat 150 g very soft butter with an electric mixer on medium speed for 3‑4 minutes until light, fluffy, and pale.
Time: PT4M
Combine Custard and Butter
Remove the plastic wrap from the cooled custard. Add the custard to the butter two tablespoons at a time, beating on medium speed until each portion is fully incorporated before adding the next.
Time: PT8M
Assemble Cake
Poke small holes evenly across the bottom pastry layer. Spread a generous layer of cream over it, fill the deeper “waves” with extra cream, then place the second pastry layer on top and press gently.
Time: PT10M
Chill Assembled Cake
Cover the assembled cake with plastic wrap and refrigerate for at least 4 hours, preferably overnight, to set.
Time: PT4H
Finish and Serve
Remove the cake from the ring, smooth the cream on the sides, dust with powdered sugar, slice and serve.
Time: PT5M
