Boston Cream Pie: Silky and Rich

Instructions:

1. Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
2. Beat softened butter and sugar until light and fluffy. Add eggs one at a time, ensuring each is fully incorporated.
3. Alternate adding the dry ingredients (flour, baking powder, salt) and wet ingredients (milk, vanilla) to the butter mixture, starting and ending with the dry ingredients.
4. Divide batter evenly between the two pans. Bake for 30-35 minutes until a toothpick comes out clean. Cool completely on a wire rack.
5. In a medium heavy-bottomed saucepan, whisk together sugar, cornstarch, and salt. Whisk in egg yolks until smooth.
6. Gradually whisk in milk. Place over medium heat, stirring constantly with a whisk until the mixture thickens and bubbles.
7. Remove from heat and stir in butter and vanilla bean paste until smooth. Cover with plastic wrap touching the surface and chill until set.
8. Heat heavy cream until simmering, then pour over finely chopped semi-sweet chocolate and butter. Let sit for 5 minutes, then stir until smooth and glossy.
9. Slice the cooled cakes in half horizontally to create four thin layers (or use two thick layers). Spread a thick layer of pastry cream over the bottom cake layer and top with the second cake layer.
10. Pour the chocolate ganache over the top of the cake, using an offset spatula to create a smooth, reflective finish. Chill the assembled cake for 4 hours to ensure structural integrity before slicing.
