Ingredients

For the Vanilla Cupcakes:

  • 1½ cups all-purpose flour

  • 1½ teaspoons baking powder

  • ¼ teaspoon salt

  • ½ cup (1 stick) unsalted butter, room temperature

  • ¾ cup granulated sugar

  • 2 large eggs, room temperature

  • 2 teaspoons vanilla extract

  • ½ cup whole milk, room temperature

For the Pastry Cream Filling:

  • 2 cups whole milk

  • ½ cup granulated sugar

  • 4 large egg yolks

  • ¼ cup cornstarch

  • 2 tablespoons unsalted butter

  • 1 teaspoon vanilla extract

  • Pinch of salt

For the Chocolate Ganache:

  • ½ cup heavy cream

  • 4 ounces semi-sweet chocolate, finely chopped

  • 1 tablespoon unsalted butter (optional, for shine)

Equipment Needed

  • Cupcake/muffin tin (12-cup)

  • Paper cupcake liners

  • Mixing bowls

  • Hand or stand mixer

  • Saucepan

  • Whisk

  • Piping bag or zip-top bag (for filling)

  • Spoon or offset spatula (for ganache)

Instructions

Step 1: Prepare the Cupcakes

  1. Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners.

  2. In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.

  3. In a large mixing bowl, cream the butter and sugar together until light and fluffy (about 3 minutes).

  4. Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.

  5. Add the dry ingredients in three parts, alternating with the milk. Begin and end with the dry ingredients.

  6. Divide the batter evenly among the cupcake liners, filling each about 2/3 full.

  7. Bake for 18–20 minutes or until a toothpick inserted in the center comes out clean.

  8. Let cupcakes cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

Step 2: Make the Pastry Cream

  1. In a medium saucepan, heat the milk over medium heat until it begins to steam but not boil.

  2. In a separate bowl, whisk the egg yolks, sugar, cornstarch, and salt until smooth and pale yellow.

  3. Slowly pour the hot milk into the egg mixture while whisking constantly to temper the yolks.

  4. Return the mixture to the saucepan and cook over medium heat, whisking continuously until it thickens (about 3–5 minutes).

  5. Remove from heat and stir in butter and vanilla extract.

  6. Transfer to a bowl, cover with plastic wrap (press it directly on the surface to prevent a skin from forming), and refrigerate until completely cool.

Step 3: Fill the Cupcakes

  1. Once the cupcakes are cool, use a paring knife or cupcake corer to remove a small core from the center of each.

  2. Spoon the chilled pastry cream into a piping bag or zip-top bag and snip the corner.

  3. Fill each cupcake cavity with the pastry cream until just level with the top.

Step 4: Make the Chocolate Ganache

  1. Heat the heavy cream in a small saucepan or microwave until it just starts to simmer.

  2. Pour over the chopped chocolate in a bowl and let sit for 2 minutes.

  3. Stir until smooth and glossy. Stir in the butter if using.

  4. Let ganache cool slightly before using so it thickens enough to stay on top of the cupcakes.

Step 5: Assemble the Cupcakes

  1. Spoon or drizzle a small amount of ganache over each filled cupcake.

  2. Let the ganache set slightly before serving, or chill for a firmer finish.

Tips for Success

  • Make Ahead: You can bake the cupcakes and prepare the pastry cream a day in advance. Store cupcakes at room temperature and keep the pastry cream refrigerated.

  • Pastry Cream Consistency: If your cream is too thick after chilling, stir it vigorously or whisk in a splash of milk before piping.

  • Flavor Twist: Add a teaspoon of espresso powder to the ganache for a mocha spin or a bit of citrus zest to the pastry cream for brightness.

  • Serving Suggestion: These cupcakes are best served slightly chilled, especially in warmer weather.

Storing & Freezing

  • Refrigerate: Store filled cupcakes in the refrigerator for up to 3 days. Let sit at room temperature for 10–15 minutes before serving.

  • Freeze (Unfilled): You can freeze the unfilled cupcakes for up to 2 months. Thaw at room temperature before filling and topping.
