Preparation

1. Make the custard: In a medium saucepan, whisk together egg yolks and sugar until well combined. Whisk in cornstarch and salt. In a slow, steady stream, whisk in milk and then the cream. Add butter. Cook mixture over medium-low heat, stirring constantly with a wooden spoon, just until it starts to thicken. Immediately whisk mixture until smooth, then continue to cook and stir custard until it has come to a very low boil for 2 minutes, about 6 to 8 minutes total. Strain custard through a fine mesh sieve into a small bowl, pushing it through with a small spatula. Stir in vanilla. Cover with plastic wrap, pressing the plastic directly onto the surface. Chill for at least 3 hours and up to 24 hours.
2. Prepare the cake: Heat oven to 325 degrees. Butter a 9-by-2-inch round baking pan, generously greasing the sides, and line it with parchment paper. Butter parchment paper. In a medium bowl, whisk together flour, baking powder and salt.
3. In a small saucepan, bring the milk and butter to a simmer over medium heat. When the butter is melted, remove pan from heat. In a large bowl, beat eggs and sugar with an electric mixer until pale and thick, about 4 to 6 minutes. With the mixer running on low, add the milk mixture and beat until combined. Then add flour mixture and vanilla and beat until combined.
4. Transfer batter to the prepared pan and smooth the top. Bake until a toothpick inserted into the center comes out clean, 30 to 35 minutes.
5. Transfer to a rack and let cool 10 minutes. With a very thin knife, cut around the edge to release the cake from the side of the pan. Carefully flip the cake onto the rack, then turn it right-side-up to cool completely.
6. Assemble the cake: Using a serrated knife, carefully cut the cake into two layers and place the bottom layer on a serving plate. Stir custard, and spread it onto the cut side of the bottom half. Replace the top half of the cake, cut side down.
7. Prepare the glaze: In a small saucepan over medium-low, heat the cream to a simmer. Remove the pot from the heat and pour cream over the chocolate chips, oil, salt and let stand for 3 minutes. Whisk until smooth. Spread the glaze evenly over the top of the cake.

Tip

• Leftover cake should be covered loosely and stored in the refrigerator. It will last about two days.
