Custard Base

  • 300 grams (1 1/4 cups) milk
  • 137 grams (2/3 cup) sugar
  • 1 large egg
  • 1 large egg yolk
  • 20 grams (2 1/2 tablespoons) cornstarch
  • 50 grams (1/4 cup) butter

Pistachio Base

  • 80 grams (2.8 ounces) cream cheese
  • 200 grams (3/4 cup + 2 tablespoons or 7 ounces) whipping cream
  • 50 grams (1/4 cup) pistachio paste
  • 15 grams (2 tablespoons) powdered sugar
  • 10 grams (2 teaspoons) vanilla paste


  • Mixing Bowls

    Essential for combining your ingredients. Use a set of various sizes for convenience.

  • Whisk

    Helps achieve a smooth texture in the custard base. A good whisk is key to thorough mixing.

  • Medium Saucepan

    Perfect for heating the milk. Opt for a thick-bottomed pan to prevent burning.

  • Stand Mixer or Hand Mixer

    Ideal for whipping up the pistachio base till it’s light and fluffy.

  • Plastic Wrap

    To cover the custard base and prevent a skin from forming.


Step 1

1. In a mixing bowl, combine the sugar, egg, egg yolk, and cornstarch. Whisk until smooth. Make sure there are no lumps in the mixture for a smoother custard.

Step 2

2. Heat the milk in a saucepan over medium heat until it is hot but not boiling. Slowly pour the hot milk into the egg-sugar mixture, stirring constantly to prevent the eggs from cooking. Pour the milk in a thin stream while whisking to temper the eggs gradually.

Step 3

3. Return the mixture to the saucepan and cook over low heat, stirring continuously until it thickens. Stir constantly to avoid lumps and prevent the custard from sticking to the bottom of the pan.

Step 4

4. Remove the thickened mixture from heat and add the butter, stirring until the custard is smooth and the butter is fully incorporated.

Step 5

5. Cover the custard base with plastic wrap, ensuring the wrap touches the surface to prevent a skin from forming. Allow it to cool to room temperature. Cooling the custard base to room temperature helps avoid condensation and excess moisture in the final mixture.

Step 6

6. For the pistachio base, whip the cream cheese, whipping cream, pistachio paste, powdered sugar, and vanilla paste together until smooth and fluffy. Chill the bowl and beaters for better whipping results.

Step 7

7. Once the custard base is cooled, blend it using a blender to ensure it’s smooth. Combine it with the pistachio base by mixing with a mixer until well incorporated and fluffy.

Looking for a gluten-free version? Simply swap out the cornstarch for an equal amount of gluten-free cornstarch or tapioca starch. To make it vegan, replace the milk with a plant-based alternative like almond or oat milk, use a vegan butter substitute, and swap the eggs with a mixture of 1 tablespoon of ground flaxseed and 3 tablespoons of water, allowing it to sit until it becomes gel-like. For the cream cheese, opt for a vegan version, and your decadent dessert will be completely free from animal products.


  • How can I prevent lumps in my custard?

    Make sure to whisk continuously while adding the hot milk to the egg mixture, and keep stirring over low heat until it thickens.

  • Can I use store-bought pistachio paste?

    Absolutely! Store-bought pistachio paste works great and saves time, but make sure to choose a high-quality one for the best flavor.

  • How do I know when the custard base is thick enough?

    The custard should coat the back of a spoon, and if you run a finger through it, the line should stay clear without running.

  • Is there an alternative to using cling film “in contact”?

    You can use parchment paper cut to the size of your bowl and place it directly on the surface of the custard to prevent a skin from forming.

  • Can I make this pastry ahead of time?

    Certainly! You can prepare both the custard and pistachio bases a day in advance, store them separately in the fridge, and combine them just before serving.

  • How do I achieve the fluffiest pistachio base?

    Make sure your ingredients are chilled and whip them at a high speed until light and airy. A stand mixer usually yields the best results.
