Tablespoons: I use a standard Australian tablespoon measuring 20ml (which equals 4 teaspoons). Be sure to check the size of your tablespoon before measuring. Butter for greasing: I like to lightly grease the donut pan with butter, but you can also use spray oil. Use only a small amount and make sure to spread it evenly around the pan holes right before piping the batter, as excess grease can pool. This recipe makes enough batter for 10 donuts. If you have just one pan, bake one batch first, then after removing the donuts, wash and lightly grease three holes before piping and baking the remaining donuts. Achieving the right glaze consistency takes some practice since different brands of sugar and the temperature of your Biscoff spread will affect its thickness. If the glaze is too thick, the donuts may break apart when dipped; if too thin, it will run off the sides without setting properly. It’s best to keep the glaze on the thicker side and spoon it over the donuts if needed.
