1. Preheat oven to 350 degrees F. Line two baking sheets with parchment paper, or grease and flour the pan well so the cookies don’t stick. In a medium bowl, sift together flour, cocoa, baking soda and salt.
2. Using a mixer, 5 Tablespoons of butter with the granulated sugar until fluffy, about 3 minutes. Beat in the egg, food coloring and 1 teaspoon vanilla. Beat in the flour mixture alternately with the buttermilk until smooth.
3. Place 1/4-cup scoops of batter 2 inches apart of the prepared baking sheet, spread the batter out with a butter knife, so they’re not completely flat but spread out a bit. Bake until a toothpick inserted in the center comes out dry, 12 to 15 minutes. Let the cookies sit for 5 minutes, then transfer to a rack to cool.

To make the glazes:

1. In a bowl, whisk together the powdered sugar, 1/2 teaspoon vanilla extract, 1 tablespoon of corn syrup and 2 tablespoons hot water, until smooth. That’s your vanilla glaze.
2. In a seperate bowl, melt the butter and the chocolate in a microwave for about 1 minute. Add the corn syrup and stir until smooth. That’s your chocolate glaze!
3. Once the cookies are cooled, face them all bottom side up of a clean surface. Spread half of the cookie with vanilla glaze and the other half with chocolate glaze. Refrigerate for 20 minutes to set. And…
4. Yum!
