Creamy Chocolate Cookies (Print Version)

# Ingredients:

01 - 1 cup of room-temperature unsalted butter (used for the cookie part).
02 - 3/4 cup of white sugar.
03 - 3/4 cup of packed dark brown sugar.
04 - 1 large egg.
05 - 1 and 2/3 cups of regular flour.
06 - 2/3 cup of cocoa powder.
07 - 1 teaspoon of table salt.
08 - 1/2 teaspoon of baking soda.
09 - 3/4 cup softened unsalted butter (used for the filling).
10 - 2 cups of powdered sugar.
11 - A tablespoon of milk.
12 - Half a teaspoon of vanilla extract.
13 - 1/2 teaspoon kosher salt (this is for the filling).

# Instructions:

01 - Whip butter with both sugars to make it fluffy, about 3-5 minutes. Stir in egg. Add flour, cocoa powder, salt, and baking soda, mixing until it's all blended together.
02 - Divide your dough into two parts. Roll each out between parchment paper to about 1/8 inch thickness. Let it chill for 30-40 minutes.
03 - Use a cutter to make circles about 1 1/2 inches wide. Place the circles on lined pans, keeping them an inch apart. Bake in a 350°F oven for 12-14 minutes—look for them to firm up.
04 - Beat butter until creamy. Slowly mix in powdered sugar, followed by milk, vanilla, and the salt, until it’s light and fluffy.
05 - Spread or pipe some filling onto the flat side of one cookie, then press another cookie on top, flat sides touching.

# Notes:

01 - A hand mixer works just as well as a stand mixer.
02 - Leftover dough can be rolled out again.
03 - They’ll keep for a week if stored at room temp.
