A dash of milk vs cream during the fast?

Hi, I’m just wondering if 1/4 of a cup of milk in the morning coffee breaks the fast? I’m toying with 6 hour eating window for the intermittant fasting. Can you give me the reason why cream doesn’t break the fast? I’m grieving ahead-of-time at the thought of loosing my morning, slighly milky coffee, if I eat between noon and 6pm. Just the thought of cream makes me gag.
Any help would be great,
