Making Silky Boston Cream Cupcakes involves several straightforward steps. Follow these to create your delicious treats:

For the Cupcakes

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line a muffin tin with cupcake liners.

2. Mix Dry Ingredients: In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt.

3. Cream Butter: In a separate mixer bowl, beat the softened butter until creamy.

4. Add Eggs and Buttermilk: Add the eggs, buttermilk, and vanilla extract to the butter. Beat until well combined.

5. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, stirring until the batter is smooth.

6. Fill Cupcake Liners: Divide the batter evenly among the prepared cupcake liners, filling each about two-thirds full.

7. Bake: Bake in the preheated oven for 20-25 minutes or until a toothpick inserted in the center comes out clean.

8. Cool: Remove from the oven and allow cupcakes to cool in the pan for about 10 minutes. Then transfer to a wire rack to cool completely.

For the Vanilla Custard Filling

9. Prepare the Custard: In a saucepan, whisk together the milk, sugar, cornstarch, and salt over medium heat until it begins to bubble.

10. Thicken the Mixture: In a separate bowl, whisk egg yolks. Gradually add a little of the hot milk mixture to temper the eggs, then add everything back into the saucepan.

11. Cook the Custard: Continue cooking while stirring constantly until the mixture thickens. Remove from heat, add vanilla extract and butter, and mix until smooth. Cover with plastic wrap and set aside to cool.

For the Chocolate Ganache Topping

12. Make the Ganache: Heat heavy cream in a saucepan until just boiling; pour it over the chocolate chips in a bowl. Let it sit for a couple of minutes, then stir until smooth.

Assembling the Cupcakes

13. Fill the Cupcakes: Once the cupcakes are completely cooled, cut a small cone out of the center of each cupcake; fill with vanilla custard using a piping bag.

14. Top with Ganache: Drizzle or dip the filled cupcakes into the chocolate ganache to coat the tops.

15. Set Ganache: Let the ganache set for about 15-20 minutes before serving.
