Reduce the heat to 325℉ after the crust finishes baking.
In a large bowl, add the cream cheese, sugar, and flour. Use a hand mixer to combine on med-low speed until smooth, 30-40 seconds.
16 oz cream cheese, ⅔ cup sugar, 1.5 tablespoon flour
Add the eggs one at a time, mixing on low until just combined each time and scraping the bowl well between additions.
2 eggs
Add the vanilla, sour cream, and heavy cream. Combine on low until just combined, scraping the bottom and sides of the bowl again.
1 teaspoon vanilla, ¼ cup sour cream, ¼ cup heavy cream
Divide the batter evenly into the 12 cupcake liners. They should be almost full.
Bake at 325℉ for 18-20 minutes, or until the centers just barely jiggle. Be careful not to overbake.
Cool fully at room temperature for 1-2 hours, then place in the fridge uncovered to chill for 2-3 more hours, or overnight. Serve with your favorite topping!
