Cook's Note: If using unbleached all-purpose flour instead of unbleached pastry flour, reduce the flour quantity to 1 1/2 cups.

For the filling: In a saucepan, combine the sugar, water, apples, cinnamon, and salt. Cook until the apples soften, about 3 minutes. Remove from the heat and add the vanilla. Cool.

For the cupcakes: Preheat the oven to 325 degrees F. Line standard cupcake pans with 14 cupcake liners.

Sift the flour, baking powder, baking soda, sea salt, cinnamon, nutmeg, cloves, allspice, ginger, and cayenne pepper into a medium bowl and whisk together. In a liquid measuring cup, mix the buttermilk and vanilla extract. In the bowl of an electric mixer fitted with the paddle attachment, cream the butter and sugar, about 5 minutes. Add the eggs, 1 at a time, scraping down the sides of the bowl after each addition. Turn the mixer to the lowest speed and alternate adding the flour mixture and buttermilk mixture, beginning and ending with the flour.

Fill the cupcake liners 3/4 full. Place 1 teaspoon Apple Filling on top of each cupcake and lightly swirl into the batter. Bake until golden brown, 17 to 20 minutes. Cool the cupcakes completely.

For the frosting: In the bowl of an electric mixer fitted with the paddle attachment, cream the butter with the salt until smooth. Add 1/2 the powdered sugar and mix thoroughly. Add the cream, vanilla, and remaining powdered sugar and beat to desired consistency.

For the topping: Combine the walnuts and blue cheese, making sure to crumble the mixture after it is combined. Set aside.

To assemble: Frost each cupcake with a wide, flat "pillow" of vanilla frosting. Dip the frosted cupcake into the walnut and blue cheese topping. To finish, drizzle the cupcake with honey.
