How to add two selectors together in css

hi there so my problem is idk how to add two selectors together so they have both the same function
i am currently in step 52 in learn basic of css by building a cafe menu and i seem not to figure it out
here is what it says:
Something does not look right. You added the correct class attribute value to the p element with Donut as its text, but you have not defined a selector for it.

Since the flavor class selector already has the properties you want, just add the dessert class name to it.

We need to see your code.
