Step 5: Combine the cheeses
While the crust is toasting, combine the following ingredients into a large bowl. If you have a counter top mixer use that, if not, an electric hand mixer works fine too.
3 packages of cream cheese (24oz)
1 cup sour cream
1 cup sugar
Stick the cream cheese, sour cream, and sugar in a bowl and mix on medium for a couple minutes. I recommend taking the cream cheese out of the fridge and hour or so before you start so it can soften up. If you don't, you might get chunks of cream cheese in your cheesecake. It happened to me the first time I made cheesecake. Since then I been letting it get to room temperature before mixing.
