Boston Cream Pie with Chocolate Ganache: 45 Minute Recipe

Instructions:

1. Preheat your oven to 350°F (175°C). Prepare two 8 inch round cake pans by greasing them with butter and lining the bottoms with parchment paper. Note: This ensures the cakes release without tearing.
2. Whisk 1.5 cups flour, 1 cup sugar, 1.5 tsp baking powder, and 0.5 tsp salt in a large mixing bowl. Make sure there are no large clumps of flour before adding liquids.
3. Gradually pour in 0.75 cup milk, 6 tbsp of the melted (and cooled) butter, 2 eggs, and 1 tsp vanilla extract. Whisk until the batter is smooth and no dry streaks remain.
4. Divide the batter equally between the two pans. Use a spatula to smooth the tops so they bake evenly.
5. Bake for 23–25 minutes until the tops are pale gold and spring back when touched. Let them cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
6. For the filling, whisk 2 cups milk, the remaining 0.5 cup sugar, 0.25 cup cornstarch, and 4 egg yolks in a cold saucepan. Whisking while cold prevents cornstarch lumps from forming later.
7. Place over medium heat and whisk constantly until the mixture thickens and begins to bubble lazily. Once it boils, keep whisking for exactly 1 minute to cook out the starch taste.
8. Remove from heat and stir in the remaining 2 tbsp butter and 1 tbsp vanilla bean paste. Strain the mixture through a fine mesh sieve into a clean bowl.
9. Press plastic wrap directly onto the surface of the custard. Note: This prevents a skin from forming as it cools. Chilling for at least 2 hours is essential.
10. Place one cake layer on a plate and spread the chilled custard to the very edges. Top with the second cake layer, pressing down very gently to anchor it.
11. Prepare the ganache by heating 0.5 cup heavy cream until it just starts to simmer. Pour it over 4 oz of chopped chocolate and 1 tbsp corn syrup.
12. Let the chocolate sit for 5 minutes until softened and melty. Stir gently starting from the center until it becomes glossy and dark.
13. Pour the ganache over the center of the cake, allowing it to naturally drip down the sides. Let it set for at least 15 minutes before slicing. When assembling the layers, the process feels very similar to constructing an [Ice Cream Cake](https://tastedessert.com/recipes/ultimate-homemade-ice-cream-cake/), where temperature management is everything. If the custard is still warm, it will soak into the cake and make it soggy. If the ganache is too hot, it will run off the cake entirely. Patience during the cooling phases is what separates a messy dessert from a masterpiece.
