🛒 Ingredients

5 servings

5
  • 400 g (14 oz) sweetened condensed milk
  • 200 g (7 oz) unsalted butter, softened
  • 300 g (10.5 oz) walnut halves
  • 1 pinch of sea salt

Directions

  1. 1

    Allow the butter to soften at room temperature for about 15 minutes until it is pliable and easy to blend.

  2. 2

    Place the walnuts in a food processor and pulse a few times to coarsely chop them, keeping some small chunks for a pleasant texture.

  3. 3

    Add the condensed milk and softened butter to the processor and blend until smooth and creamy.

  4. 4

    Stir in the sea salt, then refrigerate the filling for 30 minutes before spreading to allow it to firm up slightly.

💡 Chef's Tip

Perfect for filling chocolate tarts, layer cakes, or sandwich cookies. For extra depth of flavor, lightly toast the walnuts in a dry pan for 3 minutes before blending.
