Ingredients

  • For the chocolate syrup
  • 1 cup coffee, any temperature
  • 1 cup cocoa powder
  • 1/2 cup sugar
  • 1/2 teaspoon kosher salt
  • 1 teaspoon vanilla extract
  • For the black & white milkshakes
  • 1/4 cup whole milk, plus more as needed
  • 2 tablespoons chocolate syrup, plus more for drizzling
  • 1 pint vanilla ice cream
  • 2 tablespoons malted milk powder
  • 1 pinch kosher salt

Method

  • Combine the coffee and sugar in a small saucepan. Bring to a simmer to dissolve the sugar, then whisk in the cocoa powder and salt. Whisk until completely smooth and thick enough to completely coat your spoon-this should only take a few minutes. Stir in the vanilla. Chill completely before using for the milkshakes.
  • Before you're ready to get started, stick the glasses you'll be using in the freezer. (Or don't, but it'll help keep that shake extra frosty.)
  • Add the milk, chocolate syrup, ice cream, malted milk powder, and salt to a blender. Blend just until smooth.
  • Drizzle a bit of chocolate syrup in the bottom of the glasses. Add some milkshake. Drizzle some chocolate syrup. Add some milkshake. Repeat this until you've used all the milkshake.
  • Drink with a straw-that's required!
