Black and White Cookies

Black and White Cookies — Thermomix TM7

Black and White Cookies are classic New York-style cake-like cookies with a soft vanilla and lemon crumb, finished with the iconic half-chocolate, half-vanilla icing. The Thermomix makes light work of creaming butter and sugar, grating lemon zest and grinding homemade vanilla sugar for an even batter every time.

About this recipe

Black and White Cookies Thermomix TM7 style bring the famous New York deli biscuit straight into your kitchen, and they are easier than you might expect. These cake-like cookies, softly domed with a hint of organic lemon and homemade vanilla sugar, are the kind of dessert that looks impressive yet comes together quickly in an all-in-one kitchen machine. The TM7 takes care of the fiddly steps: it creams the unsalted butter and sugar into a light, fluffy base, blends the eggs and whole milk evenly into the batter, and grinds vanilla sugar to a fine powder so every cookie tastes consistent. The pastry flour and corn starch mixture gives the crumb its delicate, almost cake-like structure, while the two-tone finish of white confectioners sugar icing and dark chocolate glaze delivers that iconic look. Perfect for afternoon tea, bake sales, birthday tables or a weekend baking project with children, this recipe turns a classic American treat into an achievable Thermomix TM7 dessert that looks as good as it tastes.

Preparation tips

  • Chill the glazed Black and White Cookies on a wire rack until the chocolate half sets completely, otherwise the two icings will bleed into each other and you lose the crisp dividing line that makes these cookies so recognisable.
  • Grate only the yellow zest of the organic lemon in the Thermomix bowl before adding other ingredients; the white pith underneath adds bitterness that overwhelms the delicate vanilla flavour of the cookie base.
  • For the neatest two-tone effect, spread the white confectioners sugar icing first, let it tack up slightly, then pipe or spread the melted chocolate over half of each cookie using a small palette knife.
  • Store the cookies in a single layer in an airtight tin with baking paper between them; the soft pastry flour and corn starch crumb stays tender for two to three days this way.

Recipe variations

  • Lactose-free version: replace the whole milk with a neutral plant-based alternative such as oat milk and use a lactose-free butter substitute in the same quantities; the lemon zest and vanilla sugar keep the flavour of the Black and White Cookies intact.
  • Festive version: add a few drops of almond extract to the batter and decorate the white icing with coloured sprinkles or fine lemon sugar pearls for birthdays, holidays or a bake-sale stall with eye-catching appeal.
