Baking Instructions
Preheat your oven to 350°F (175°C) and line a standard cupcake pan with liners.
In a large mixing bowl, cream together unsalted butter and granulated sugar using an electric mixer on medium speed for about 3-4 minutes until light and fluffy.
Blend in the sour cream and vanilla extract, then gradually add egg whites in two batches, mixing until smooth.
In a separate bowl, whisk together flour, baking powder, and salt. Mix milk and water, then gradually incorporate both mixtures into the wet batter.
Fill each cupcake liner halfway with batter and bake for 15-17 minutes, checking doneness with a toothpick.
While the cupcakes cool, prepare the pastry cream by whisking sugar, cornstarch, and milk over medium heat until thick and bubbly, then temper in the egg yolks.
For the ganache, heat the heavy cream until steaming, pour over chocolate chips, and whisk until smooth.
Cut out the center of each cooled cupcake and fill with pastry cream.
Drizzle or spread the ganache over the filled cupcakes.
Notes
Allow cupcakes to cool completely before filling with pastry cream. Use room temperature ingredients for best results.
