Measuring 150g of butter without a scale

No scale? 150 g of butter is about ⅔ cup (0.66 cups), or roughly 11 tablespoons using standard US measuring cups and spoons. Spoon it in and level off the top instead of scooping, which packs in extra.

150 grams is a backbone quantity in classic British baking, where it pairs neatly with 150g sugar and three eggs for a Victoria sponge or a batch of fairy cakes. It equals about two-thirds of a cup, or one and a third US sticks, so on a stick-marked wrapper you would use a full stick plus a third of another. At this amount, creaming temperature really matters: butter should be soft enough to whip pale and airy, which is what gives a 150g sponge its lift.
