Notes
Make sure all ingredients are room temperature. This will ensure the cheesecake is smooth, creamy and lump free.
Don’t mix on high speed. I mix all ingredients on low-medium speed. You don’t want to overbeat the cheesecake batter. You also don’t want the batter to be airy, as this can cause air bubbles, which can result in cracking of cheesecake.
Whisk the eggs first before adding to the cheesecake batter. Whisking the eggs first reduces the chance of air bubbles in the batter which will result in a smooth and creamy cheesecake texture.
Don’t overbake. Bake until cheesecake is just set, but still jiggly in the center. It will continue baking as it cools off in the oven.
Don’t rush the cooling process! You’ll need to cool the cheesecake in the oven. This ensures it doesn’t crack or sink.
For best results let the cheesecake sit in the refrigerator overnight. This lets all the flavors come together and help the cheesecake firm up.
