Step-by-Step Instructions
- Preheat your oven to 350°F (175°C), and line a standard cupcake pan with liners.
- In a large mixing bowl, beat the butter and sugar until light and fluffy for about 3-4 minutes.
- Mix in sour cream and vanilla extract, then gradually add egg whites until fully incorporated.
- In a separate bowl, whisk together flour, baking powder, and salt.
- Combine milk and water in a measuring cup.
- Alternately add the dry ingredients and milk-water mixture to the creamed butter mixture until just combined.
- Spoon the batter into cupcake liners and bake for 15-17 minutes, or until a toothpick comes out clean.
- Let the cupcakes cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
- For the pastry cream, whisk sugar, cornstarch, and milk in a saucepan over medium heat until thickened, about 5-7 minutes.
- Whisk egg yolks and gradually add hot milk mixture, then return to the saucepan and cook until thickened.
- Stir in butter and vanilla extract, allow it to cool to room temperature.
- For ganache, pour heated cream over chocolate chips and let sit for 5 minutes before whisking until smooth.
- Core the cupcakes, fill with pastry cream, and top with chocolate ganache.
- Refrigerate until ready to serve; serve closer to room temperature for best taste.
