Cu p Cookies are a milk 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 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 a bit of history about Baker’s Ammonia.

Ammonia Cakes: probably the least appetizing cookie name that I’ve ever come across. These cakes use ammonium bicarbonate (baker’s ammonia) as the leavening agent and I assure you that they don’t taste like ammonia, but they will temporarily stink up your kitchen like cat urine while they bake! Ammonia Cakes fall on the bland side of the cookie spectrum, so I was lucky to find the recipe Icing for Cake in the same recipe book and I iced them the next day.

If you do want to make a cookie using Baker’s Ammonia as the leavening agent, I really do suggest baking Cup Cookies instead. It’s just a more flavourful cookie!
