Key Lime and White Chocolate Tiramisu

Servings 6



  • 2 eggs, separated
  • 45 grams’ confectioners’ sugar, sifted
  • 250 grams’ white chocolate, melted
  • 12 oz. (350 grams) mascarpone cheese
  • 1 teaspoon freshly squeezed lime juice
  • Finely grated zest of 1 lime
  • 6 tablespoons milk
  • 125 ml/ 4 fl. oz. instant coffee, prepared
  • 20-22 savoiardi (or ladyfingers)

To garnish (optional):

  • white chocolate shavings (optional)
  • lime zest (optional)




  • Using an electric mixer, beat the egg yolks and sugar together until creamy. Then, add the mascarpone cheese and mix all over again. Set aside.
  • Next, melt the white chocolate over a double-boiler or in a microwave. Add the mascarpone mixture and combine well.
  • In a separate bowl, beat the egg whites and fold into the mascarpone mix. Pour the lime juice and the lime zest. Combine to incorporate.
  • In a shallow dish, pour the milk and add the coffee. Next, dip the ladyfingers into the mixture long enough to soften, and arrange ½ of the savoiardi/ladyfingers in the base of the pan.
  • Spread over a 1/3 of the mascarpone mix and top with a layer of the remaining dipped savoiardi/ladyfingers. Spoon the remaining mascarpone mixture over the top and sprinkle extra lime zest all over the tiramisu cake (if desired). Cover and refrigerate for 2-3 hours to set.
  • Before serving, decorate with white chocolate shavings (if desired).

Buon Appetito!
