Black and White 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.

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.

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

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!
