This recipe makes about 6 1/2 pounds of cake, and you can divide that between pans of different sizes. Size will depend on whether you are making cake for one, or two, or several households—you might want to give smaller cakes away as gifts.
For the record, this recipe will make two, nine-inch round cakes that weigh a little over 3 ¼ pounds each. But I almost never make two big cakes—I have a small household and I give quite a few cakes away.
For this iteration of the recipe, I used round glass Anchor brand storage bowls, which are oven safe up to 400F. I filled each bowl with batter 2-inches deep, except the smallest bowl. This is how the weight per volume worked out for me.
One 6 1/2-inch bowl filled with batter 2 inches deep: one two-pound cake.
Two 5-inch round bowls filled 2 inches deep: two 1 1/2-pound cakes.
Two 4-inch round bowls filled 2 inches deep: two 10-oz cakes.
One 3-inch round bowl filled 2 1/2 inches deep: one 7-oz cake.
