Grate butter instead of cutting it into recipes
For recipes that call for cut butter or folded butter -- like pies, biscuits, and croissants -- grate the butter into the dry mix for the same effect with less effort.
Make buttermilk in 10 minutes with ingredients you already have
Stir together 1 cup milk with 1 tablespoon lemon juice (or white vinegar). Let it sit at room temperature until thick and slightly curdled, about 10 minutes.
Bring cold butter to room temperature quickly
Many baking recipes call for butter at room temperature, but that can take at least 30 minutes. Save some time with this cheat. Cut butter into chunks. Fill a glass bowl with hot water. Pour out the water and invert the hot bowl to cover the butter. Let sit for 2 minutes, uncover, and use.
Soften crispy cookies
