Dry ingredients are spooned into the cup and levelled. Scooped straight from the bag, flour can weigh up to 20% more — for baking, a scale is the safest bet.
Good to know:
- Powdered (icing, confectioners') sugar is light and fluffy: a cup is about 120 g — little more than half a cup of granulated sugar.
- It settles and clumps in the bag, so sift it before measuring for frosting: lumps don't dissolve in buttercream.
- US powdered sugar has a little cornstarch to stop caking. That's fine in frostings and glazes, but don't swap it for granulated sugar in a cake.
