• 1/4 cup powdered sugar
• 1/2 tsp cinnamon (or nutmeg for variation)
• 1/4 tsp nutmeg
• 1/4 tsp salt
• 1/2 cup cold unsalted butter (or dairy-free margarine)
• 1 large egg yolk (or flax egg for vegan option)
• 2–3 tbsp cold water

For the Mousse

• 1 cup heavy cream (or whipped coconut cream for dairy-free)
• 1/2 cup milk (or almond milk for non-dairy version)
• 1 tsp gelatin (or agar-agar for plant-based alternative)
• 8 oz white chocolate (or vegan white chocolate)
• 1 tsp vanilla extract (or seeds from 1 vanilla bean)

Instructions

Step 1: Prepare the Crust

1. In a mixing bowl, combine flour, powdered sugar, cinnamon, nutmeg, and salt.
2. Cut in butter until the mixture resembles coarse crumbs.
3. Add egg yolk and cold water, mixing until dough forms. Chill for at least 30 minutes.

Step 2: Blind Bake the Tart Shell

1. Preheat oven to 350°F (175°C).
2. Roll out dough into a tart pan, prick with a fork.
3. Bake with pie weights for 15 minutes, remove weights, then bake 10 more minutes until golden. Cool completely.

Step 3: Make the White Chocolate Mousse

1. Bloom gelatin in cold water if using.
2. Heat milk gently, dissolve gelatin, then stir in white chocolate and vanilla until smooth. Let cool slightly.
3. Whip cream to soft peaks and gently fold into the chocolate mixture.

Step 4: Assemble the Tart

1. Pour mousse into cooled tart shell, smoothing the top.
2. Refrigerate at least 4 hours or overnight until fully set.
