Step-by-Step Instructions

Step 1: Make the Cupcakes

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and line a muffin tin with cupcake liners.
   
2. Mix Dry Ingredients: In a medium bowl, combine the all-purpose flour, sugar, baking powder, and salt. Whisk to combine.
   
3. Cream Butter and Sugar: In a separate large bowl, beat the softened butter and sugar together using an electric mixer on medium speed until light and fluffy, about 2-3 minutes.
   
4. Add Eggs and Vanilla: Add the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract.
   
5. Combine Dry and Wet Ingredients: Gradually add the dry ingredients to the wet ingredients, alternating with the milk, starting and ending with the dry ingredients. Mix until just combined.
   
6. Fill the Cupcake Liners: Spoon the batter into the cupcake liners, filling each about 2/3 full.
   
7. Bake: Bake for 18-20 minutes, or until a toothpick inserted into the center of a cupcake comes out clean. Let the cupcakes cool completely on a wire rack.
   

Step 2: Make the Vanilla Custard Filling

1. Heat the Milk: In a medium saucepan, heat the milk over medium heat until it starts to simmer, then remove it from the heat.
   
2. Whisk the Egg Yolks: In a separate bowl, whisk together the sugar, cornstarch, and egg yolks until smooth.
   
3. Temper the Eggs: Slowly pour the hot milk into the egg yolk mixture while whisking constantly to avoid curdling the eggs.
   
4. Cook the Custard: Pour the mixture back into the saucepan and cook over medium heat, whisking constantly, until it thickens. This should take about 4-5 minutes.
   
5. Finish the Custard: Remove the saucepan from the heat and stir in the butter and vanilla extract. Allow the custard to cool to room temperature, then refrigerate it for at least 30 minutes to thicken further.
   

Step 3: Make the Chocolate Ganache

1. Heat the Cream: In a small saucepan or in the microwave, heat the heavy cream until it just begins to simmer.
   
2. Combine with Chocolate: Pour the hot cream over the chopped chocolate in a mixing bowl. Let it sit for 2-3 minutes to melt, then stir until smooth and glossy.
   
3. Add Butter: Stir in the butter until the ganache is silky smooth. Let it cool to room temperature before using.
   

Step 4: Assemble the Cupcakes

1. Core the Cupcakes: Once the cupcakes have cooled, use a small knife or a cupcake corer to remove a small portion from the center of each cupcake, creating a well for the custard filling.
   
2. Fill with Custard: Spoon or pipe the chilled custard filling into the center of each cupcake.
   
3. Top with Ganache: Spoon or drizzle the chocolate ganache over the top of each filled cupcake, spreading it to cover the top completely.
   
4. Chill: Refrigerate the assembled cupcakes for about 30 minutes to set the ganache before serving.
   

Pro Tips

• Make the Custard Ahead: The custard can be made a day in advance and refrigerated. This will help you save time on the day you’re making the cupcakes.
  
• Customize the Filling: Feel free to add a splash of liqueur like Grand Marnier or rum to the custard for a flavor twist.
  
• Use a Spoon or Piping Bag for the Ganache: For a smoother ganache topping, use a spoon to gently pour the ganache over the cupcakes, or pipe it using a piping bag for more control.
  
• Gluten-Free Version: Swap the all-purpose flour with a gluten-free flour blend and ensure your baking powder is gluten-free.
  
• Dairy-Free Option: Use dairy-free butter, non-dairy milk, and a dairy-free ganache option for a delicious dairy-free version of these cupcakes.
