   Time: PT5M

2. Crumb the biscuits

   Crumb the Breton shortbread biscuits and the Petit Beurre biscuits using a food processor or by hand until you obtain a fine powder.

3. Mix with melted butter

   Melt the butter gently (microwave 30 s or bain‑marie). Incorporate it into the crumbled biscuits and mix until you obtain a homogeneous dough.

   Time: PT4M

   Temperature: 45°C

4. Form the base

   Pour the dough into the 20 cm springform pan, press firmly with the back of a spoon to form a compact base.

   Time: PT2M

5. Melt the milk and speculoos paste

   In a saucepan, heat the milk with the speculoos paste over medium heat, stirring constantly, until the mixture is smooth and melted (about 5 min).

   Time: PT5M

   Temperature: 60°C

6. Incorporate the gelatin

   Remove the saucepan from the heat, add the drained gelatin and stir until it is completely dissolved.

   When the milk‑speculoos mixture has cooled to room temperature, pour it gradually into the mascarpone bowl while gently folding with a spatula.

    Time: PT5M

11. Refrigerate

    Cover the cake with plastic film and place it in the refrigerator for at least 6 hours, ideally overnight, so the mousse sets.

    Time: PT0M

    Temperature: 4°C

12. Prepare the speculoos glaze

    Melt the remaining speculoos paste in the microwave (30 s at medium power) or bain‑marie, until you obtain a smooth coating.
