We like using sweetened condensed milk to make it a much more authentic Tahoe Joe's cheesecake recipe. However, as we have mentioned before, many people find it too sweet. Instead, you can substitute it with evaporated milk (which is basically unsweetened condensed milk) or a dairy-free option like cream of coconut.
To add a tangy flavor to this cheesecake recipe, you can add some sour cream over it once it has finished baking. Then, place it back into the oven for another 5 minutes. This will help balance out the sweet flavors of the condensed milk and to create a sweet flavor profile.
