The Complete Guide to Cheesecake Ingredients (and How They Affect Flavor & Texture)

The ingredients in a cheesecake matter more than the techniques used to make it. Even small changes in the ingredients can create dramatically different results. Changes can affect the creamy, smooth texture or the density. 

Knowing the purpose of every major cheesecake ingredient and how they affect the flavor, texture, and appearance will give you the tools to make cheesecake perfectly every time.

Starting with the foundation: cream cheese. Cream cheese is rich and tangy, giving the cheesecake a great structure. Cream cheese creates a dense, creamy texture in a cheesecake. However, not all cream cheeses are created equal. There are three types that I want to look at: full-fat, reduced-fat, and whipped cream cheese. 

Full-Fat Cream Cheese: This is the best for cheesecake, but why? Well, the fat is necessary for the texture and flavor of a cheesecake. 

Reduced-Fat Cream Cheese: Because it has less fat, it has more moisture. That moisture makes the batter runny and prevents the cheesecake from setting properly.

Whipped Cream Cheese: Whipped versions contain extra air. Even though air is a good thing for a cheesecake, too much of it can cause the structure to collapse in the oven.

More than just the sweetener: Sugar. Yes, granulated sugar is what makes desserts in general sweet. However, there is more to it than that, as sugar helps with moisture retention. The sugar helps retain the moisture of the cream cheese and eggs, aiding slow, even baking. This helps the cheesecake not have a grainy texture. Even baking is crucial for the creaminess and firmness of a cheesecake.

The structure builder: Eggs. Eggs are essential for binding, stability, and richness in cheesecake. If you add too few eggs to the batter, then the cheesecake won’t set up properly. So the final result will be runny and soft. However, adding too many eggs will make the cheesecake rubbery and dense. Along with the sponge-like texture, the flavor will be egg-heavy. 

Dairy ingredient: Sour cream. Is it necessary to add sour cream to cheesecake? No, it’s not. However, sour cream enhances the creamy texture, making a cheesecake less dense. Sour cream also adds a tanginess that is most often found in New York-style cheesecakes. 

Dairy ingredient: Heavy cream. Heavy cream plays a role similar to sour cream. However, a cheesecake with only one of the two will bake differently. Heavy cream adds liquid fat, creating a silkier texture. Heavy cream compliments cream cheese’s natural tang, whereas sour cream enhances it. 

Flavor enhancer: Vanilla extract. Vanilla extract does a lot more than add a little flavor to a cheesecake. Vanilla balances the tangy flavor of the cream cheese. Vanilla also ‘overpowers’ the egg taste.

Flavor enhancer: Lemon juice. Lemon juice is hit-or-miss in cheesecake recipes; however, it does play a role. Lemon juice cuts the rich, heavy taste of cream cheese and smooths it out. By doing this, lemon juice helps prevent lumps in the batter. 

Flavor enhancer: Salt. Salt is a flavor enhancer. Mainly it enhances the cream cheese and the sugar. Salt brings out the cream cheese’s natural tang while balancing its richness. Salt also keeps a cheesecake from being overly sweet or one-note in flavor. 

Thickening Ingredients: Cornstarch and flour are both used to thicken a cheesecake batter and help it set up nicely. Adding either isn’t necessary; however, if your recipe has a lot of liquids or you are unable to use a water bath they act as a safety net. The texture difference cornstarch and flour bring is firmer and less creamy. They bind moisture and stabilize the egg proteins.

The crust ingredients: Now, the crust doesn’t directly affect how the cheesecake batter sets up. However, there are some differences between these ingredients. For instance, the base can be made from graham crackers, digestive biscuits, or cookies. The taste will change more than the texture for all these options. The butter acts as a binding agent and adds to the flavor. Salt, much like in the cheesecake batter, acts as a flavor enhancer in the crust. Lastly, sugar adds sweetness and helps with binding and a crisper texture. 

Using room temperature ingredients matters. For cheesecake, making sure all the ingredients are the same temp, prevents lumps from forming in the batter. Doing this will keep the cheesecake smooth and creamy, so it bakes properly.
