Crush the cookies into fine crumbs using a food processor or place them in a zip-top bag and crush with a rolling pin. Mix with melted butter until combined. Press firmly into a 9-inch springform pan to form the crust. Place in the freezer for about 15 minutes to set.
While the crust chills, wash your dandelion flowers and separate the yellow petals. You’ll need about 2 cups.
Soak the gelatin sheets in very cold water with a few ice cubes until soft.
In a small pot, heat the orange juice with half of the sugar over medium heat (don’t let it boil). Add the dandelion petals and simmer for about 2 minutes. Stir in the chopped oranges.
Remove from heat, add the softened gelatin, and gently mix them into the juice until fully dissolved.
Pour about 2/10 of the dandelion-orange mixture over the chilled crust. Place the pan in the refrigerator and chill for 1 hour, or until set.
In a bowl, whip the heavy cream until soft peaks form.
In a small pot, heat the remain (about 1/2 cup) orange juice with the rest of the sugar. Add the soaked gelatin and stir until dissolved. In another bowl, mix the warm (not hot) orange juice into the mascarpone cheese until smooth. Gently fold in the whipped cream to make the second layer.
Spread the mascarpone layer over the set dandelion layer. Chill until firm.
Reheat the remaining dandelion-orange mixture (2/10), process to smooth, and pour it over the top as the final layer. Chill again until fully set.
To remove the springform, wrap a hot towel around the pan for a minute to loosen the edges.
Decorate with dandelion flowers, orange slices, and edible wild blooms.
Enjoy your little dandelion slice of spring — bright, simple, and made with love!
