Sift flour, baking powder, baking soda, and salt into a medium bowl, then whisk until well combined (this may take up to 1 minute). Add the butter, toss to break up the pieces, and smash each cube flat. Continue smashing and rubbing until the butter has mostly disappeared into a floury mix, although a few larger, Cheerio-sized pieces may remain. This can also be done with 4 or 5 pulses in a food processor, just take care not to overdo it. The prepared mix can be refrigerated up to 3 weeks in an airtight container, then used as directed below.
