The Best Black and White Cookies.

Hi everyone! I’m Olivia, 14; Rock Recipes founder Barry’s daughter. This is my first official guest blogger story, and today I’m going to share one of my favourite cookies out there, the famous Black and White New York cookie. 

 Many have never even heard of the deli classic, also known as a “half moon” or an “Amerikaner”.  It is basically a light, fluffy, cakey cookie with a hint of lemon, topped with vanilla icing on one side and rich chocolate icing on the other.

So simple, but boy are they good!

My first time trying Black and White Cookies.

I had my first Black and White cookie back in 2008 during the family road trip across the eastern coast of Canada and the United States. 

Dark Chocolate Chips, to melt and dip the biscotti

Dark chocolate chips are best for the frosting both for appearance and flavour.

We stayed in New York City for three days during 4th of July weekend, and I was nearly peeing my pants with excitement (that happened to also be my first 7/11 Double Gulp, not fun during an eight hour car ride, yikes!). 

I remember pulling out of the Lincoln Tunnel and seeing Manhattan for the first time. Needless to say I was absolutely shocked by the amount of people, traffic and places.

I myself had never been more than a few hours away from St. John’s NL, quite a different environment than the bustling metropolis of Manhattan.

An amazing first trip to New York City

My brother Noah and I were unusually quiet those days; partly because we were so excited we had no words to describe it, partly because we were shaking in our skin due to the fact we had never been more terrified in our lives. 😉

We stayed just outside of Times Square in the Milford Plaza. That first day, I was overcome with the amount of food there was! Fast food joints around every corner, diners, crazy street vendors, there was so much variety!

As the day came to a close, just as I had finished my very first experience of the bliss of a Nathan’s Hot Dog, Dad suggested we go to the deli across the street from the hotel to grab a snack.

There, in that deli, I saw it. A fat cookie approximately the size of my head perfectly coated in vanilla and chocolate which met straight down the middle.

I took a bite down the center, and knew this was the cookie for me, and trust me- I know a good cookie!

Perfecting my recipe for Black and White Cookies

So four years later I remembered the black and white cookies as I was looking through our road trip album, and was determined to make them for Rock Recipes

My first batch was unfortunately a flop, much too dense and not sweet enough, like an overdone pancake. With some alterations I whipped out a second batch, and I found my perfect New York Black and White Cookie!

Soft and cake-y with a perfect crumb and a slight lemony flavour, enrobed in a smooth buttery vanilla icing and rich chocolate, so uh yeah, they’re amazing.

So without further ado, my take on the Black and White Cookie… and if a fourteen year old can do it, so can you! 😉

For the cookies

  • 2 1/2 cups cake flour
  • 2 1/2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 2 cups sugar
  • 1 cup butter
  • 4 large eggs
  • 2 tsp vanilla extract
  • 1/2 tsp very finely minced lemon zest1
  • 1/2 cups milk

For the Black and White Frosting

  • 1/2 cup butter
  • 4 cups icing sugar (i.e powdered sugar)
  • 3- 4 tbsp milk
  • 1 tsp vanilla extract
  • 3 squares melted unsweetened chocolate
  • 1 or 2 tbsp milk


  1. Preheat oven to 375 degrees F.
  2. Sift together the cake flour, all-purpose flour, baking powder and salt and set aside.
  3. Cream together the sugar and butter very well.
  4. Add the eggs, one at a time, beating well after each addition.
  5. Add the vanilla extract and lemon zest.
  6. Fold in the dry ingredients alternately with the milk.
  7. Be sure to begin and end your additions with the dry ingredients. As a rule, I add dry ingredient in 3 equal portions and the milk in two.
  8. Drop heaping tablespoons of the batter onto a parchment lined cookie sheet, leaving 2 to 3 inches between the cookies.
  9. Bake for 15-20 minutes, depending on the size of your cookies or until the center of the cookies spring back when touched.
  10. Cool completely on a wire rack.
  11. Frost the BOTTOM of the cookies with black and white frosting.
  12. To prepare the black and white frosting.
  13. Mix together the butter and icing sugar
  14. When the butter has broken down into small pieces and the mixture is crumbly add the milk and vanilla extract.
  15. Whip this mixture until it is light and fluffy. You may need a little more milk to bring it to a thick but still spreadable consistency.
  16. Reserve half of the frosting and to the other half add the melted chocolate and  the 1 or 2 tbsp milk.
  17. Beat until the chocolate is well incorporated and the icing is uniformly smooth.
  18. Use a piping bag or a Ziploc bag with the corner snipped off, pipe a line of vanilla frosting down the center of the cookie.
  19. Carefully frost one side of the cookies with the vanilla frosting and the other side with the chocolate frosting.
  20. Leave the cookies uncovered for a couple of hours for the frosting to set.
  21. Do not stack these cookies when storing.
