Be sure to set out the cream cheese and eggs about an hour before starting the recipe.
In a small bowl, add the crushed graham crackers, butter and sugar.
Spray the slow cooker with nonstick spray.
Add the graham cracker mixtture and press down on the bottom of the slow cooker. I do this with the bottom of a drinking glass.
In a large bowl add the softened cream cheese, eggs, sugar and vanilla extract. Using a hand mixer with beaters, beat until smooth.
Pour the cheesecake mixture into the crust.
Cook on HIGH For 2 hours without opening the lid during the cooking time.
Take the slow cooker insert out and put it on a cooling rack. Before you let the cheesecake cool, run a butter knife around the edge of the cheesecake. This will help prevent the cheesecake from cracking. I like to put the cheesecake in the fridge to cool. When the cheesecake is completely cooled and set, slice and serve!
