Put a cup of sugar in the blender and turn it on, adding 2 tablespoons of cornstarch if you want. (Commercial powdered sugar has cornstarch in it to keep it from clumping. You can do the same if you like. But if you are using it immediately, there’s really no need. If you are making it ahead, then perhaps you should.)

Blend at a high speed for 30 seconds or so, depending on your blender. Eyeball the stuff. You may need to stir things around and go at it again, but the Damsel found no need. Good grief, it was really that easy.

An interesting note: 1 cup of granulated sugar makes a bit more than 1 cup powdered. That seems backwards to the Damsel’s brain. Many things seem backwards to the Damsel’s brain, including why children get stupider as they grow older. But she has made peace with her brain’s behavior and hopes the best for you and your own struggle for true perception.
