Cup Cookies are a mild lemon sugar cookie with an almond, sugar & cinnamon topping sprinkled on top. This recipe is from Aunt Babette’s Cook Book from 1889, and its leavening agent is Ammonium Bicarbonate or Baker’s Ammonia.

I’ve chosen this recipe because for the last 2 years, my Ammonia Cakes recipe has been my most popular blog post by far. That shows me that there’s an appetite for information about and recipes using Baker’s Ammonia, but I’m torn, because Ammonia Cakes is not a delicious recipe at all! I had to make a second recipe, Icing for Cake to save the Ammonia Cakes so they were edible and they didn’t end up in the compost.

Cup Cookies are a much more delicious ammonium bicarbonate cookie. Stick with this recipe for the deliciousness, but head over to Ammonia Cakes for background and history about Baker’s Ammonia.
