sorghum substitute
in cake.
Sorghum provides the structural backbone of Cake, forming the crumb structure through gluten development and starch. Substitutes must match absorption and binding.

adjustment for this dish
Millet flour is drier and more mildly flavored than sorghum — add 1 tablespoon milk per cup to keep the crumb moist, and keep baking powder at 1.5 teaspoons per cup (millet also has no gluten). The tender crumb emerges lighter colored than a sorghum cake, so brush with a milk wash before baking for even browning.

Barley

Not GF but similar chew
10.0
adjustment for this dish
Barley flour contains 5-8% gluten, so you can drop baking powder back to 1.25 teaspoons per cup (vs sorghum's 1.5) and cream for only 4 minutes rather than 5. The crumb bakes slightly denser but more stable; sift the barley flour with the powder once is enough — no double sift needed.

Buckwheat

Chewy and neutral; pop like popcorn too
10.0
adjustment for this dish
Buckwheat flour darkens the crumb and adds a tannic note that pairs with citrus or chocolate; swap 1:1 cup and keep baking powder at 1.5 teaspoons, but cream butter and sugar a full 5 minutes because buckwheat's denser particles need more aeration. Check the toothpick at 32 minutes — buckwheat bakes faster than sorghum.

Higher protein GF alternative

adjustment for this dish
Quinoa flour has 15% protein and a saponin note; toast at 300°F for 6 minutes first, then swap 1:1 cup. Reduce sugar by 1 tablespoon per cup because toasting concentrates sweetness, and keep baking powder at 1.5 teaspoons. The tender crumb rises slightly higher than sorghum's.
technique for cake
technique
5 teaspoons baking powder per cup (25% more than a wheat cake) to compensate. Add eggs one at a time and scrape twice to emulsify before the flour goes in — a broken batter produces a gummy crumb in sorghum cakes specifically because the starch absorbs free water fast.
Fold the batter until just smooth and bake at 335°F, not 350°F, for 35-40 minutes to give the crumb time to rise slowly without doming; check with a toothpick at the center. Cool in the pan 10 minutes before turning out.
Unlike brownies, which want a dense, fudgy set and minimal leaven, cake needs the creaming, the extra baking powder, and the gentler oven to produce a tender, moist crumb. Unlike cookies, the cake batter is a controlled slurry shaped by the pan rather than a dough that spreads, so hydration is higher and chill time is unnecessary.
Unlike muffins, which take a rough 12-stroke fold to keep them rustic, cake demands a thoroughly smoothed batter to avoid streaks.
pitfalls to avoid
watch out
Increase baking powder by 25% (to 1.5 teaspoons per cup of sorghum) — sorghum crumb is heavier than wheat and the extra leaven is what gives the cake tender lift.
watch out
Sift the sorghum flour with the baking powder twice before adding to the creaming bowl; clumps of dense flour settle during bake and produce gummy pockets in the crumb.
watch out
Don't fold the batter more than 20 strokes after the flour goes in; sorghum starch tightens under mechanical stress and the crumb loses its moist, open structure.
watch out
Cool the cake in the pan exactly 10 minutes before turning out — longer and the bottom steams, shorter and the tender structure tears when you invert.
watch out
Whisk eggs into the creamed butter one at a time with a full 30-second scrape between additions to keep the emulsion — a broken batter bakes gummy in sorghum specifically.
