90 Grams of Butter to Cups
90 grams of butter equals ⅜ cup (0.4 US cups), based on 227 g per cup (level cup). In the kitchen, measure 6 tbsp. For best results, weigh butter with a scale — cup measurements vary with how the cup is filled.
Small amounts like this fit in a single cup measure with room to spare; the fraction matters more than the cup, so level carefully.

How to measure 90 g of butter without a scale
In the US, butter is easiest to measure by the wrapper: one stick is ½ cup = 8 tbsp = 113 g, and the wrapper is printed with tablespoon marks. For amounts that aren’t clean stick fractions, weigh it — cutting soft butter into a measuring cup traps air pockets.
