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

...or use some dental floss wrapped/pulled around the cake's middle to "cut" the cake in half...
I had the same problem and searched the web ... the eggs should be whipped first and after 5 minutes then incorporate the sugar. Here's the info:
https://www.google.com/amp/s/bakingisascience.com/2014/07/11/hotmilk-cak...
A couple of earlier reviewers asked why not make the 2 layers in 2 pans. I suspect I know why since I had to do it myself (my 9" cake pans are only 1.5" deep and not 2" as called for). If you make 1 cake, the 2 surfaces created by cutting in half are rougher and more absorbent which helps keep the pudding layer in place. The shinier/smoother surfaces of 2 separately baked cake layers makes it easier for the pudding and then the upper cake layer slide off the lower layer (as happened to me!)
I recently made this and was pleased with the outcome. However, next time(absolutely)I will double the filling and take 1/3 of the cake from the middle. The cake is dense as others have stated but it works well in this recipe.
A few key things I will change next time.. 1. Cake: cook less or changes recipe. Cake was really hard, yes I followed the suggestion of whipping eggs for 5'ish minutes before adding sugar. Maybe I cooked it too long, but the toothpick wasn't coming out clean (ended up cooking for 7 extra minutes. ) 2. Custard: Needs way more custard. Planning of doubling the recipe next time. 3. Chocolate: Made my own chocolate frosting. Wasn't sure the glaze in this recipe was going to give me what I wanted. I like for of a frosting top coating.
Wonderful, I made mine with Gluten-free flour, and it is delicious and easy to make!
