Ingredients

  • 1 1/2 cups all-purpose flour
  • 1 1/2 cups cake flour (not self rising)
  • 1 tablespoon baking powder
  • 1 tablespoon cinnamon, plus more for dusting
  • 1/2 teaspoon kosher salt
  • 1 3/4 cup sugar, plus more for dusting
  • 1 cup unsalted butter, room temperature, plus more for brushing
  • 4 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 1/4 cup whole milk
  • 2 cups sugar
  • 12 tablespoons unsalted butter, room temperature
  • 1 teaspoon pure vanilla extract
  • 1 cup heavy cream, room temperature
  • 1/2 cup unsalted butter
  • 8 ounces cream cheese
  • 1 teaspoon pure vanilla extract
  • 4 to 4 1/2 cups powdered sugar
  • Milk
  • 4 tablespoons unsalted butter

Method

  • Special equipment: Cupcake corer
  • For the cake batter: Preheat the oven to 350 degrees F. Line two 12-cup muffin pans with cupcake liners.
  • In a medium bowl, sift together the flours, baking powder, cinnamon and salt.
  • In the bowl of a stand mixer fitted with a paddle attachment, cream the sugar and butter on medium-high speed until light and fluffy.
  • Add the eggs, one at a time, beating until just incorporated.
  • Beat in the vanilla.
  • Reduce the mixing speed to low.
  • Add the flour mixture in three batches, alternating with the milk.
  • Beat until combined.
  • Divide the batter evenly among the lined cups, filling each three-quarters full.
  • Bake until a toothpick comes out clean, 18 to 20 minutes.
  • Transfer to a wire rack and cool completely.
  • For the filling: Combine the sugar and 1 tablespoon water into a medium bowl over medium-high heat.
  • Constantly stir until the sugar dissolves into a liquid form.
  • The sugar will dissolve and start to turn brown.
  • Once the sugar and water have completely dissolved, add in the butter and vanilla.
  • Slowly whisk in the heavy cream.
  • Let cool for 10 minutes.
  • Refrigerate for 1 hour to let the caramel thicken before using.
  • For the frosting: Beat the butter and cream cheese until light and creamy.
  • Add in the vanilla.
  • Add in the powder sugar, 1 cup at a time, incorporating fully before next addition.
  • Add milk as needed if the frosting is too thick.
  • Place the frosting into a piping bag fitted with a large star tip.
  • Once the cupcakes have cooled, pull out the centers with a cupcake corer.
  • Melt down the butter.
  • Mix together some cinnamon and sugar in a small bowl.
  • Using a rubber brush, brush the melted butter onto the cupcakes, then roll the tops of the cupcakes into the cinnamon-sugar mixture.
  • Fill the cupcakes with the caramel sauce.
  • Frost cupcakes with cream cheese frosting, dust with more cinnamon and sugar.
  • If you choose, drizzle the cupcakes with leftover caramel sauce.
