Ingredients

  • 2 cups cake flour
  • 2 teaspoons baking powder
  • 1 teaspoon fine salt
  • 12 tablespoons unsalted butter (1 1/2 sticks), at room temperature
  • 1 1/2 cups granulated sugar
  • 1 vanilla bean, split lengthwise and scraped, seeds reserved (or 1 tablespoon vanilla extract)
  • 2 large egg whites, at room temperature
  • 2 large eggs, at room temperature
  • 3/4 cup whole milk, at room temperature
  • Salted Caramel Frosting (see recipe intro)

Method

  • Heat the oven to 350 degrees F and arrange a rack in the middle.
  • Line 2 (12-well) muffin pans with paper liners.
  • Alternatively, coat the wells with butter; set aside.
  • Combine flour, baking powder, and salt in a medium bowl and whisk to aerate and break up any lumps; set aside.
  • Place butter in the bowl of a stand mixer fitted with the paddle attachment and beat on medium-high speed until very light in color, about 3 minutes.
  • Add sugar and vanilla seeds (if youre using vanilla extract instead, youll add it later), and continue beating until the mixture is airy, about 3 minutes.
  • Scrape down the paddle and the sides of the bowl, turn the mixer to medium speed, and add the egg whites one at a time, beating well after each addition.
  • Then add the eggs one at a time, beating well after each addition.
  • Add the milk (and vanilla extract, if youre using it in place of seeds) and mix until combined (the mixture will look curdled, but its not).
  • Scrape down the sides of the bowl.
  • Reduce the speed to low, add the reserved flour mixture, and mix until just combined, about 15 seconds.
  • Fill the muffin wells about halfway and bake until the cupcakes are golden brown and a toothpick inserted into the center comes out clean, about 18 minutes.
  • Set the pans on a wire rack and let cool for 5 minutes.
  • Remove the cupcakes from the pans and let cool completely before frosting.
