I don't have measurements or a real recipe for this treat, because you shouldn't have to think on Sunday mornings. So here's a pictorial:
Pull out your French press and add a spoonful or so of cocoa powder and lots more spoonsful of coarse ground coffee. I use decaf and still get a buzz, but use whatever you want.
Add boiling water and let sit for a while. Not sure how long. You shouldn't have to use timers on Sunday morning.
This is the best part. Now scoop a little scoop of vanilla ice cream into a glass or mug and pour the cocoa coffee over it. Enjoy and then try to talk yourself out of a second cup.
