Ingredients

For Filling:

  • 1 1/2 cups unsalted butter
  • 6 cups 1 1/2 lbs confectioners' sugar
  • 3/4 tsp pure peppermint extract
  • 3 tbsp Horizon Organic Milk

For Cookies:

  • 3 ½ cups all-purpose flour
  • 1 ½ cups unsweetened cocoa powder
  • 2 tsp baking powder
  • 1 tsp baking soda
  • ½ tsp salt
  • 1 cup butter room temperature
  • 2 cups granulated sugar
  • 2 large eggs
  • 1 cup Horizon Organic Milk
  • 1 cup sour cream
  • 2 tsp vanilla extract
  • 1/4 cup crushed candy canes

Instructions

To make cookies:

  • Preheat oven to 350ºF. In a large bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
  • Beat butter and sugar in a standing mixer until light and fluffy, about 2 minutes, pausing occasionally to scrape down sides and bottom of bowl with a rubber spatula. Beat in eggs, one at a time, for about 30 seconds each, pausing to scrape down sides.
  • With mixer speed on low, beat in milk, sour cream, and vanilla extract, followed by the flour mixture.
  • Drop by level tablespoonfuls onto parchment-lined baking sheets. Bake 4 minutes, remove from the oven and sprinkle each with a bit of crushed candy cane, then bake 2 minutes more. Cookies are done when set but still a bit shiny (if you press the centre, it will leave an indent). They will look underdone - this is essential to chewy, delicious cakes.

To make filling:

  • Combine all ingredients in stand mixer with whisk attachment and beat until light and fluffy, about 2 minutes. 

To assemble:

  • Spread a heaping tablespoonful of frosting onto flat side of one cookie. Sandwich with another cookie, and transfer to a plate. Transfer to the fridge after you’ve frosted every half-dozen or so, as the filling is gooey and will start to spread out. Continue until all the cookies have been sandwiched. Keep refrigerated until ready to serve.
