Ingredients
Scale
Cupcakes
- 12 tablespoons unsalted butter, softened
- 1 cup sugar
- 2 teaspoons vanilla extract
- 3 eggs
- 1 ½ cups all-purpose flour
- 2 teaspoons baking powder
- ½ teaspoon salt
- ⅔ cup buttermilk
Pastry Cream Filling
- 3 egg yolks
- 3 cups milk
- ½ cup sugar
- ⅓ cup cornstarch
- ¼ teaspoon salt
- 1 teaspoon vanilla extract
Chocolate Ganache
- 8 ounces semi-sweet baking chocolate, finely chopped
- 1 cup heavy cream
Instructions
- Cream Butter and Sugar: In a large mixing bowl, cream together the softened butter and sugar until light and fluffy. This creates the base for the cupcakes, ensuring a soft and tender crumb.
- Add Vanilla and Eggs: Add the vanilla extract to the creamed butter and sugar, then beat in the eggs one at a time, mixing well after each addition to ensure a smooth, fully combined batter.
- Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, and salt to ensure even distribution of the leavening agents and salt.
- Mix Wet and Dry Ingredients: Alternate adding the flour mixture and buttermilk to the creamed mixture in three batches, starting and ending with the dry ingredients. Beat after each addition just until combined to avoid over-mixing the batter.
- Prepare Cupcake Pan: Lightly grease a muffin pan and line it with cupcake liners. Fill each liner three-quarters full with the batter to guarantee even, consistent cupcakes.
- Bake Cupcakes: Bake the cupcakes in a preheated oven at 350°F (175°C) for 18 to 25 minutes, or until a toothpick inserted into the center comes out clean. Transfer cupcakes to a wire rack to cool completely before filling and topping.
- Prepare Pastry Cream Filling: In a medium bowl, beat the egg yolks thoroughly. Gradually stir in the milk until well blended. In a heavy saucepan over medium-low heat, combine sugar, cornstarch, and salt. Slowly add the milk and egg mixture to the saucepan, stirring continuously to prevent lumps. Cook the mixture over medium-low heat, stirring constantly, until it thickens and reaches a low boil, approximately 20 minutes. Remove from heat and place the saucepan in an ice water bath to cool slightly. Stir in the vanilla extract, then cover the surface with plastic wrap and refrigerate until chilled and ready to use.
- Make Chocolate Ganache: Place the finely chopped semi-sweet chocolate in a mixing bowl. Heat the heavy cream in a small saucepan over medium heat until steaming but not boiling. Pour the hot cream over the chocolate and let it sit undisturbed for 1 to 2 minutes to melt the chocolate. Whisk the mixture until smooth and glossy. Allow the ganache to cool until thickened yet still pourable.
- Assemble Cupcakes: Using a piping bag fitted with a filling tip, fill each cooled cupcake by inserting the tip into the center and gently squeezing to fill with the prepared pastry cream filling.
- Dip in Ganache: Dip the tops of the filled cupcakes into the cooled ganache, swirling gently to coat evenly. Place the cupcakes on a wire rack and allow the ganache to set for 30 minutes to 1 hour before serving for the best texture and flavor.
Notes
- Ensure butter is softened to room temperature for easy creaming.
- Do not overmix the batter once flour is added to avoid tough cupcakes.
- Use fresh eggs for the best pastry cream texture and flavor.
- Chill pastry cream well before filling cupcakes to prevent leaking.
- If ganache becomes too thick, gently warm it to regain pourable consistency.
- Store filled cupcakes in the refrigerator and consume within 2-3 days.
