Ingredients

For the cookies:

  • 270 g (2 ⅓ cups) all-purpose flour
  • ½ teaspoon baking powder
  • ¼ teaspoon baking soda
  • 170 g (12 tablespoon) unsalted butter, room temp
  • 200 g (1 cup) granulated sugar
  • ½ teaspoon salt
  • 1 egg, room temp
  • 1 egg yolk, room temp
  • 1 tablespoon vanilla extract
  • 113 g (½ cup) sour cream, room temp

For the chocolate icing:

  • 56 g (¼ cup) heavy cream
  • 28 g (1 oz ) dark chocolate
  • 28 g (¼ cup) powdered sugar, sifted
  • 15 g (1 tablespoon) light corn syrup

For the vanilla icing:

  • 170 g (1 ½ cups) powdered sugar, sifted
  • 84 g (¼ cup + 2 tbsp) heavy cream
  • 15 g (1 tablespoon) light corn syrup

Instructions

For the cookies:

  • Preheat the oven to 350 degrees F and line two large baking sheets with parchment paper.
  • In a medium bowl, combine the flour, baking powder, and baking soda.
  • In a large bowl, cream together the butter, sugar, and salt for 2-3 minutes until light and fluffy.
  • Mix in the egg, egg yolk, vanilla, and sour cream until fully combined.
  • Lastly, add the dry ingredients and mix until just combined.
  • Use a 3 tablespoon cookie scoop to portion the cookie dough onto the prepared baking sheets, spacing them about 2" apart.
  • Dip a finger in water to smooth out and pat down the cookie dough balls slightly.
  • Bake the cookies for 10-12 minutes until the tops appear matte but before the edges turn golden.
  • Allow the cookies to cool for a few minutes, then turn each of them over and set aside to cool completely.

For the chocolate icing:

  • In a small saucepan over low-medium heat, stir together the heavy cream, chocolate, powdered sugar, and light corn syrup until fully melted. Set aside to cool.

For the vanilla icing:

  • In a medium bowl, whisk together powdered sugar, heavy cream, and light corn syrup until smooth.

For assembly:

  • On the bottom of each cookie, spread the vanilla icing onto one half. Then, repeat with the chocolate icing on the other half.
  • Allow the icing to set for a few minutes, then enjoy!

Notes

  • Don't over-bake the cookies! The cookies are done baking once the tops no longer look wet, but before the edges turn golden. Even just a minute over can make these cookies dry!
  • Make the chocolate icing first. The chocolate icing needs a few minutes to cool, so I recommend making it first and using it to decorate the cookies second.
