Ingredients

• 1.5 cups All-purpose flour
• 1 cup Granulated sugar
• 1.5 teaspoons Baking powder
• 0.5 teaspoon Salt
• 0.5 cup Unsalted butter (softened)
• 0.75 cup Whole milk
• 1 teaspoon Vanilla extract
• 2 units Large eggs
• 3 units Egg yolks (for custard filling)
• 0.5 cup Granulated sugar (for custard filling)
• 2 tablespoons Cornstarch
• 1 cup Whole milk (for custard filling)
• 1 teaspoon Vanilla extract (for custard filling)
• 0.5 cup Heavy cream (for ganache)
• 1 cup Semi-sweet chocolate chips
• 1 tablespoon Unsalted butter (for ganache)

Directions

Step 1

Preheat your oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners.

Step 2

In a medium mixing bowl, combine the flour, sugar, baking powder, and salt. Whisk until well combined.

Step 3

Add the softened butter, milk, and vanilla extract to the dry ingredients. Mix until smooth and no lumps remain.

Step 4

Add the eggs one at a time, mixing well after each addition, until the batter is light and fluffy.

Step 5

Divide the batter evenly among the cupcake liners, filling each about two-thirds full.

Step 6

Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean. Allow cupcakes to cool completely on a wire rack.

Step 7

While the cupcakes cool, prepare the custard filling by whisking together the egg yolks, sugar, and cornstarch in a medium bowl.

Step 8

In a small saucepan, heat the milk over medium heat until it just begins to simmer. Slowly whisk the hot milk into the egg mixture to temper the eggs.

Step 9

Return the mixture to the saucepan and cook over medium heat, whisking constantly, until it thickens (about 2-3 minutes). Remove from heat and stir in the vanilla extract. Cover with plastic wrap directly on the surface to prevent a skin from forming and let it cool completely in the refrigerator.

Step 10

To make the ganache, heat the heavy cream in a small saucepan over medium heat until it starts to simmer.

Step 11

Remove from heat and pour the cream over the chocolate chips in a heatproof bowl. Let it sit for 5 minutes, then add the butter and stir until the mixture is smooth and glossy. Let it cool slightly until it thickens to a spreadable consistency.

Step 12

To assemble the cupcakes, use a small paring knife to cut a small cone-shaped piece out of the center of each cupcake. Fill each cavity with the prepared custard and place the removed piece of cake back on top.

Step 13

Spread a generous layer of chocolate ganache over each cupcake.

Step 14

Refrigerate the cupcakes for at least 30 minutes to allow the flavors to meld. Serve and enjoy!
