Ingredients List

  • 1 package (8 oz) cream cheese, softened
  • 1/4 cup unsalted butter, softened
  • 1/2 cup milk
  • 1/2 cup sugar, divided
  • 4 large eggs, separated (room temperature)
  • 1/4 cup all-purpose flour
  • 2 tablespoons cornstarch
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon cream of tartar
  • Powdered sugar, for dusting (optional)

Instructions

Step 1: Prepare the Pan and Preheat the Oven

  • Preheat your oven to 325ยฐF (160ยฐC).
  • Grease and line the bottom and sides of a 7-inch round springform pan with parchment paper. Make sure the paper comes slightly above the edge of the pan.

Step 2: Mix the Cream Cheese Mixture

  • In a heatproof bowl, combine the softened cream cheese, butter, and milk.
  • Set the bowl over a pot of simmering water (double boiler method) and stir until smooth and melted.
  • Remove from heat and allow the mixture to cool slightly.

Step 3: Prepare the Dry Ingredients

  • In a separate bowl, sift together the all-purpose flour and cornstarch.
  • Gradually add the sifted flour mixture to the cream cheese mixture, stirring until smooth and well combined.

Step 4: Whisk the Egg Yolks

  • In a clean bowl, whisk the egg yolks with 1/4 cup of sugar until smooth and pale.
  • Add the egg yolks to the cream cheese mixture, stirring until fully combined.

Step 5: Beat the Egg Whites

  • In a separate clean bowl, beat the egg whites and cream of tartar until soft peaks form.
  • Gradually add the remaining 1/4 cup of sugar and continue to beat until stiff peaks form.

Step 6: Fold the Egg Whites Into the Cream Cheese Mixture

  • Gently fold the beaten egg whites into the cream cheese mixture, working in batches. Be careful not to deflate the mixtureโ€”use a gentle folding motion.

Step 7: Bake the Cheesecake

  • Pour the batter into the prepared springform pan.
  • Smooth the top with a spatula.
  • Place the pan in a larger baking pan filled with hot water (about 1 inch high).
  • Bake for 50โ€“60 minutes, or until the cheesecake is golden and slightly wobbly in the center.
  • Turn off the oven and leave the cheesecake in the oven with the door slightly ajar for 10 minutes.

Step 8: Cool and Serve

  • Allow the cheesecake to cool to room temperature, then transfer it to the refrigerator for 3 hours or overnight to set completely.
  • Before serving, dust with powdered sugar for a finishing touch.

Additional Notes

  • Water Bath Tip: The water bath helps the cheesecake bake evenly, ensuring a smooth, crack-free top.
  • Texture: The key to this cheesecakeโ€™s signature fluffiness is properly folding the egg whites into the batter, so take your time.

FAQs

Can I use low-fat cream cheese?
Yes, but the texture might be slightly less rich. Full-fat cream cheese provides the best creamy texture.

How do I know when the cheesecake is done?
The cheesecake should be golden on top and set in the center. It should wobble slightly but not jiggle like liquid.
