Instructions
 

Sugar Cookies

  • In a large bowl or stand mixer, combine butter, sugar, and salt. Beat with a paddle attachment until light and fluffy, about 8 minutes. Scrape down the bowl halfway through.
    ½ cup unsalted butter, 1 cup granulated sugar, ½ teaspoon salt
  • Add egg and yolk into the butter and beat until light and fluffy. Scrape down the bowl and beat again.
    1 large whole egg, 1 large egg yolk
  • Add sour cream, vanilla, and almond extract to the bowl. Beat until light and fluffy again. Scrape down the bowl and beat again.
    ½ cup sour cream, 1 tablespoon pure vanilla extract, ¼ teaspoon almond extract
  • Sift flour, cornstarch, baking powder, and baking soda into the bowl and fold until no more dry streaks remain. Shape the dough into a disk and wrap tightly to prevent it from drying out. Refrigerate for at least 30 minutes.
    2 ½ cups all purpose flour, 2 tablespoons cornstarch, 1 teaspoon baking powder, ½ teaspoon baking soda
  • Preheat oven to 180°C or 355°F. Roll out the dough on a lightly floured surface or in between two sheets of parchment paper. Roll to ½” thickness. Using a 3” round cookie cutter, cut out circles, re-rolling the dough as needed.
  • Place the cut cookies onto a parchment lined baking sheet and pop in the freezer for 5 minutes or in the fridge for 10 minutes.
  • Bake 2-3" apart for 8-10 minutes or until lightly golden brown at the bottom and puffed at the top. Transfer to a cooling rack to cool completely.

Buttercream

  • Beat butter, sugar, and salt until light and fluffy, about 8-10 minutes. Scrape down the bowl halfway through. Add vanilla and beat until light and fluffy again.
    ¾ cup unsalted butter, 3 cups powdered sugar, ¼ teaspoon sea salt, 1 teaspoon pure vanilla extract
  • Add heavy whipping cream, a tablespoon at a time until buttercream and beat on low speed until light and fluffy.
    5-8 tablespoons heavy whipping cream
  • Set aside half of the buttercream in a separate bowl. Into the remaining frosting, add cocoa powder and beat until fully incorporated.
    ¼ cup cocoa powder
  • Add more heavy whipping cream a tablespoon at a time into the chocolate frosting to loosen if needed.
  • Frost half the cookies with vanilla buttercream and the other half with chocolate buttercream. Sprinkle with sprinkles of choice and serve! You can serve them at room temperature or refrigerated.
    5 tablespoons sprinkles
