Cake Flour — Grams & Cups Converter
1 cup of cake flour weighs about 114 g. So 100 g ≈ 7/8 cup, 200 g ≈ 1 3/4 cups, and 300 g ≈ 2 5/8 cups. Convert any amount between grams, cups, ounces, tablespoons and millilitres with the calculator below.
💡 Tip: Cake flour has less protein than all-purpose, for a tenderer crumb. No box? Per cup, remove 2 tbsp AP flour and replace with 2 tbsp cornstarch, then sift.

Cake flour vs all-purpose: weight and protein
Cake flour is milled from soft wheat to about 7–9% protein, well below all-purpose flour's 10–12%. Less protein means less gluten, which is what gives cakes their fine, tender crumb. It is also milled finer, so a cup weighs about 114g versus 120g for all-purpose.
No cake flour on hand? For each cup, measure 1 cup of all-purpose flour, remove 2 tablespoons, and swap in 2 tablespoons of cornstarch. Sift several times so the cornstarch is evenly distributed before using.
