Variations:

You can definitely use heavy cream or milk in this recipe. I would prefer heavy cream over milk because you might not get the same creaminess using milk.

If you want to make this recipe dairy-free, margarine would work well. You can also substitute half-and-half with almond milk or soy milk, or even water. Just know the taste might be a little different, and the consistency might be off.

Feel free to add a few drops of gel food coloring to match the color of your theme.
