Coffee grounds in Compost

Question

I have heard that coffee grounds are beneficial for plants, so I add them to my compost. I add a dash of ground cinnamon to the grounds because cinnamon is good for me (regulating blood sugar), so small amounts of cinnamon get into the compost. Is this still OK for planting?

Answer 1

Previously answered.

OK but too dilute to consider as a source of cinnamon.
Have a cinnamon roll with your coffee.
