- Preheat your oven to 350°F (175°C) and line a muffin tin with paper cupcake liners.
- Whisk together the cake flour, baking powder, baking soda, and salt in a medium bowl.
- In a large mixing bowl, beat the softened unsalted butter and granulated white sugar together on medium speed for 2-3 minutes until light and fluffy.
- Mix in the egg whites and vanilla extract, continuing to mix until pale and combined.
- Gradually alternate adding the dry ingredient mixture and the buttermilk into the wet mixture until just combined.
- Spoon the batter into prepared cupcake liners, filling each about two-thirds to three-quarters full, and bake for 16-18 minutes.
- Prepare the white chocolate ganache by melting chopped white chocolate and heavy cream together over a double boiler, then whip until fluffy.
- Beat softened butter until fluffy, then mix in cooled melted white chocolate followed by powdered sugar until smooth.
- Once cupcakes are cool, use a cupcake corer to create a well in each and fill with ganache, then pipe buttercream frosting on top.
