I read about ten recipes looking for the perfect Key Lime Cheesecake, to no avail. I was searching for a phenomenal cheesecake with phenomenal key lime flavor. Most of those I read had only a tablespoon or two of lime juice, and others had only a small amount of cream cheese.

So I created this, using the amounts of lime in the super lime-y ones paired with the high cream cheese content and baking method used in the America's Test Kitchen New York Cheesecake recipe. And it is amazing.
Note: if you don't own an instant-read thermometer or a kitchen scale, get one. You will never have dry cookies or over-baked custard or meat again. I have the OXO Good Grips Chef's Digital Leave-In Thermometer and highly recommend it.
Key Lime Vanilla Bean Cheesecake Recipe
Crust
2 c. graham cracker crumbs (6.5 oz, about 1.5 sleeves)
3 T. sugar (1.5 oz)
1/4 t. salt
1/4 c. butter, melted
Filling
4 8-oz packages cream cheese, at room temperature (this is important)
1/2 vanilla bean, just the seeds (you can reserve the seed pod for another use) - can use 2 t. of vanilla extract if you don't have vanilla beans
2 t. key lime zest
2 c. sugar (14 oz)
2/3 c. key lime juice
1/2 c. sour cream
1/2 t. salt
4 eggs plus 2 egg yolks
Preheat oven to 350. For the crust, combine all ingredients and press into the bottom of a greased 9-inch springform pan. Bake until fragrant but not browned - about 8 minutes. Turn the oven up to 500.
For the filling, mix the cream cheese in a stand mixer on medium-low until smooth, about 2 minutes. Don't incorporate air as this will increase the chance of your cheesecake cracking. Add the vanilla bean seeds, zest, and sugar. Mix on low until incorporated. Add juice, sour cream, and salt. Mix on low until incorporated and scrape down the sides with a spatula. Add eggs and yolks, one at a time, mixing after each addition and scraping down the sides of the bowl with a spatula. Mix another 30-60 seconds .
Pour filling over crust and bake at 500 for 10 minutes. WITHOUT OPENING THE OVEN, turn the heat down to 200 and bake for another 40-50 minutes, until the filling has an internal temperature of 150. Baking on low heat until the correct internal temperature has been reached makes for a smooth, creamy cheesecake, not the dry, egg-y mess you can sometimes end up with.
Remove the cheesecake from the oven and let it cool to room temperature. Then wrap tightly and store refrigerated. Serve with lightly sweetened whipped cream if desired, or whatever else you'd like to throw on it to put it over the top. Candied lime? Toasted coconut? Sweetened sour cream? It's pretty fantastic all by itself.
(the holes in the top of the cheesecake are from the thermometer probe. if you don't want yours to end up this dark, lightly cover the top of the pan with foil for the first half of baking time.)
