Preheat the oven to 350°F (175°C). In a mixing bowl, combine flour and sugar. Add the cold butter and mix until crumbly.

Add the egg yolk and ice water, mixing until the dough forms. Press the dough into a tart pan and prick the bottom with a fork.

Bake for 20-25 minutes or until golden. Let cool completely.

In a mixing bowl, beat the cream cheese until smooth. Add powdered sugar and vanilla extract, mixing until well combined.

In another bowl, whip the heavy cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture.

Spread the cream filling evenly over the cooled tart crust.

Top with mixed berries and drizzle with honey if desired. Chill in the refrigerator for at least 1 hour before serving.
