Preheat the oven to 350°F.
To make the crust, first whisk together the flour, sugar, and salt.
Add the melted butter and vanilla, then stir just until the ingredients are mixed and a sticky dough has formed.
Press the dough into the bottom and all the way up the sides of a 9 ½-inch tart pan with a removable bottom.
Bake the crust until it has browned lightly, about 20 minutes.
Place the tart pan on a cooling rack and let the crust cool.
While the crust cools, place all of the filling ingredients into a high-powered blender or food processor fitted with an S-blade. Blend until completely smooth and creamy, stopping to scrape down the sides of the bowl or pitcher as needed.
Pour the filling into the crust, smoothing out the top with a spatula.
Place the tart into the fridge and chill until fully set, at least 4 hours.
Optionally, garnish with fresh fruit. Slice and serve.
