Tastes like a boozy, very chocolatey Mounds candy bar. The stout beer drinking fans at our Xmas party refused to believe that there was no actual chocolate/cacao in the beer. I was very happy with the amount of coconut. I should note my measurement of the coconut extract was not actually 0.25 oz (by weight) per gallon, but rather it was a shot-glass (with lines at 0.25, 0.50, 0.75, 1.00, and 1.50 ounces) per gallon of beer. Since I had 3 gallons to bottle, I went with filling the shot glass to 0.75 -- if my memory serves, the last time I actually weighed 0.5 "volume oz" of McCormick coconut extract, the scale said it was 0.355 ounces.
If you're hoping to be ready by St Patrick's, maybe reduce the abv by a percent or two? Probably just cutting out the brown sugar would do it. Other than that, I'm planning on brewing this again next week with no recipe changes! Meanwhile, I've still got 12 bottles tucked in the beer closet, and I'm very tempted to sample one right now!
