Before keto, I'd never used baking powder in my ice cream cones, but being the eternal experimenter that I am, I thought I'd try it out. Using baking powder will give you a thinner, elegant, more delicate, lacy cone. If you're in a hurry or this is your first time making ice cream cones, I'd leave it out. Without the baking powder, your cones will rip less and be more workable (and personally, I do like them better to eat). But my kids don't notice the difference and eat them either way. I got the sweetest smiles from my 5 year old with these cones! The cones are really strong either way once they're cooled, but while working with the hot cones, it's easier to skip the baking powder the first time. The photo below shows the cones WITHOUT baking powder on the left and WITH baking powder on the right. If you look at the cones on the right, notice the light shining through the lacy cones.
