If you don’t have piping bags because you don’t bake frequently, no problem! You can use a large, sealable bag instead. To do this, fill the bag by placing it in a tall glass or cup. Drape the opening of the bag over the sides of the cup and spoon in the batter. When the batter is in the bag, remove the bag from the glass and cinch the bag shut. Use a scissors to cut about a ½ to 1 inch large triangle out of the one corner of the bag. Push the batter towards the opening and then gently squeeze the batter into the circle shaped grooves on the donut pan.
