The fastest route is the 1/3 cup measure filled twice. When halving a whole recipe, write the new amounts on the card first so you do not scoop the full 1 1/3 cups out of habit.

No 1/3 cup? Use 10 Tbsp + 2 tsp, or the 1/2 cup plus 2 Tbsp + 2 tsp.

If you bake by weight, halve the grams instead: 1 1/3 cups of spooned flour is about 160 g, so half is about 80 g (2.82 oz by weight). The half a recipe chart covers the other ingredients on the card.
