How much sour cream do you add in a box cake mix?

There's no one-size-fits-all answer for how much sour cream to add to a box cake mix! It depends on several factors:

* The recipe: Some cake mix recipes call for sour cream, and will specify the amount.

* Desired texture: Sour cream adds moisture and richness to cakes. A small amount (1/4 cup) will make a slightly denser, more moist cake. A larger amount (1/2 cup or more) will create a richer, more decadent cake.

* Flavor: Sour cream also adds a subtle tang to the cake.

Here are some general guidelines:

* For a basic cake: Start with 1/4 cup of sour cream.

* For a richer, denser cake: Use 1/2 cup or more.

* For a cake with a tangy flavor: Use a full cup of sour cream.

Remember:

* Always check the specific instructions on your cake mix box, as some mixes may include sour cream in their recipe.

* If you're adding your own sour cream, adjust the amount of liquid in the recipe accordingly.

Pro Tip: You can substitute Greek yogurt for sour cream, which will give the cake a slightly tangier flavor.
