BLACK AND WHITE TANG RECIPES

Steps:

• Do not preheat oven yet - dough mush chill before baking.
• Melt chocolate chips with butter. (Microwave on high power for 2 minutes, then stir until smooth).
• Mix in sugar.
• Allow to cool.
• Add eggs, one at a time, mixing well after each addition.
• Mix in vanilla, baking powder and salt.
• Add flour & mix well.
• Chill dough for at least 4 hours (overnight is even better).
• Preheat oven to 350 degrees with rack in middle position.
• Roll walnut-sized dough balls with you hands (this is messy, you might want to wear plastic gloves).
• Drop the balls into the bowl of confectioners' sugar & roll them around until they are covered.
• If dough gets too warm, stick it back into the fridge until you can handle it again.
• Place the balls on a cookie sheet (12 to a standard sheet works best).
• Do not flatten - they will flatten as they bake.
• Bake at 350 degrees for 12-14 minutes.
• Let them cool on the cookie sheet for 2 minutes and then remove to a wire rack to finish cooling.
• Eat and enjoy.

Steps:

• Make the cookies: Position racks in the upper and lower thirds of the oven and preheat to 350° F. Line two baking sheets with parchment paper. Whisk the flour, baking powder, baking soda and salt in a medium bowl until combined.
• Beat the butter and granulated sugar in a large bowl with a mixer on medium-high speed until light and fluffy, about 3 minutes. Add the eggs, one at a time, then the vanilla, beating well after each addition.
• Reduce the mixer speed to low and beat half of the flour mixture into the butter mixture until just combined. Beat in the sour cream, then beat in the remaining flour mixture.
• Using a large ice cream scoop or 1/4 cup measure, scoop mounds of dough and place 3 inches apart on the baking sheets (6 cookies per pan). Bake, rotating and switching the pans halfway through, until the cookies are puffed and the bottoms and edges are just starting to brown, about 15 minutes. Let cool 5 minutes on the pans, then remove the cookies to a rack to cool completely.
• Make the icing: Sift the confectioners' sugar into a large bowl. Add 3 tablespoons milk, the corn syrup and vanilla and whisk until smooth and very thick but still spreadable. Remove half of the icing (about 1/2 cup) to a separate bowl and stir in the cocoa powder until smooth, thinning with up to 1 tablespoon milk, if needed.
• Turn the cookies flat-side up. Using a small offset spatula, spread the white icing on half of each cookie, making a straight, clean line in the center of the cookie. Return the cookies to the rack, and let sit, preferably in a cool place, until the icing is firm with a matte finish, at least 30 minutes. Spread the chocolate icing on the other half of the cookies. Let the icing set at room temperature, at least 2 hours and up to overnight.
