Outstanding ideas! I always use real unsalted butter for my cookies. Texture is the issue here. I will chill the dough before using. Adding extra baking soda is a thought. For fluffy pancakes, I usually add an egg to the mix, extra baking soda, and a couple squeezes of a lemon. I then let it sit for a couple hours to leaven. In the case if cookies, it is different. Refrigeration is the better idea. I will place all the ingredients together and combine with a fork.
