Ingredients

For the white cupcakes:

  • 210 g (1 ¾ cups) cake flour
  • 162 g (¾ cup + 1 tbsp) granulated sugar
  • 2 teaspoon baking powder
  • ½ teaspoon kosher salt
  • 76 g (5 ½ tablespoon) unsalted butter, room temp
  • 50 g (¼ cup) neutral oil
  • 227 g (1 cup) whole milk
  • 2 teaspoon vanilla extract
  • 2 egg whites

For the white chocolate french buttercream:

  • 113 g (4 oz) white chocolate
  • 3 egg yolks
  • 62 g (¼ cup + 1 tbsp) granulated sugar, divided
  • 21 g (1 ½ tablespoon) water
  • 113 g (8 tablespoon) unsalted butter, room temp
  • ½ teaspoon vanilla extract

For assembly:

  • 170 g (½ cup) raspberry preserves
  • Fresh raspberries, for topping

Instructions

For the white cupcakes:

  • Preheat the oven to 350 degrees F. Add parchment liners to a cupcake pan.
  • In the bowl of a stand mixer fitted with the paddle attachment, combine the flour, sugar, baking powder, and salt.
  • Cut up the butter into small cubes and add to the dry ingredients. Mix on low speed until it resembles wet sand.
  • Add the oil, milk, vanilla, and mix until just combined.
  • In a separate bowl, whip the egg whites to medium peaks. Gently fold them into the batter with a rubber spatula until just combined.
  • Fill the cupcake liners about ⅔ of the way full.
  • Bake the cupcakes for 16-18 minutes or until a toothpick inserted comes out clean.
  • Cool completely before decorating.

For the white chocolate french buttercream:

  • In a small heat-proof bowl, add the white chocolate and place it over a pot of simmering water. Stir often until fully melted. Remove the bowl from heat and set aside.
  • Place the egg yolks and 12g (1 tbsp) of granulated sugar in a medium bowl or a bowl of a stand mixer fitted with a whisk attachment. Whisk on high speed until thick and foamy (about 3 minutes) while you heat the sugar and water.
  • Heat the remaining 50g (¼ cup) of granulated sugar and water in a small saucepan over low heat, stirring constantly until the sugar dissolves. Increase the heat to medium and bring to a boil, or until it reaches 240 degrees F.
  • While the egg yolks are whisking on medium speed, slowly add the sugar syrup into the bowl. Continue mixing until the mixture has cooled down.
  • Add the butter to the mixture a few cubes at a time, allowing them to fully incorporate before adding more.
  • Lastly, add the cooled melted white chocolate and vanilla. Continue mixing on low speed until the buttercream is completely smooth.

For assembly:

  • With a small (about 1") round cookie cutter, remove the centers of the cupcakes, pressing about ⅔ of the way into them. Cut the very top of the centers off and reserve them.
  • Fill the cupcakes with raspberry preserves and place the top of the centers back on.
  • Transfer the buttercream to a piping bag with a medium star piping tip.
  • Decorate each cupcake as desired.

Notes

  • Do not over-whip the egg whites. Whip the egg whites only to medium peaks. As you can see above, the peaks droop slightly - this is what you're looking for. Whipping them to stiff peaks will make the egg whites too dry, causing them to deflate as they're folded into the batter. 
  • Fill the cupcake liners ⅔ full. Over-filling the cupcakes can cause them to sink even though they're baked all the way through.
