Start making Mom's brunch day with thick slices of brioche. You can get great loaves at places like the Met Market... though it's probably not as good as wherever the Yankees shop.
Let the slices sit while you mix the dry ingredients (brown sugar, cinnamon, etc.) with the wet (eggs, milk, Mom's tears of joy that you're actually doing this).
Get out the rhubarb butter, which you've already made by "cooking the hell" out of some rhubarb and sugar (Oh yeah, cook the hell out of some rhubarb and sugar).
Use the aforementioned butter (or some store bought jam/preserves if you're lazy and you want to disappoint her again) to make her plate look as pretty as she definitely still is.
And for extra credit (or maybe to help you get through the day, we don't know your mom) pair the toast w/ a refreshing cocktail like Mistral's Old Cuban.
