🛒 Ingredients

5 servings

5
  • 1 package of ladyfingers or shortbread cookies
  • Milk (for soaking the cookies)
  • 1 can sweetened condensed milk (14 oz / 397 g)

Directions

  1. 1

    Prepare the gelatin according to package instructions and allow it to cool slightly.

  2. 2

    In a blender, combine the condensed milk, cream, lemon juice, and prepared gelatin. Blend until smooth and airy.

    Quickly dip the cookies in milk — just one second per side — and arrange them in a single layer on your serving dish.

  4. 4

    Pour a portion of the lemon mousse over the cookie layer and spread evenly.

  5. 5

    Continue alternating layers of soaked cookies and mousse until all ingredients are used, finishing with a mousse layer.

  6. 6

    Garnish with lemon zest or thin lemon slices for a fresh, elegant finish.

  7. 7

    Refrigerate for at least 40 minutes before serving chilled.

💡 Chef's Tip

Swap the lemon mousse for passion fruit, strawberry, or white chocolate mousse — any flavor works beautifully in this layered dessert!
