Substitute for Baking Powder in Cake: Light and Fluffy Rise
When making cake, the best substitute for baking powder is Baking Soda + Cream of Tartar. This recreates baking powder exactly. Sift with the flour to distribute evenly. Get the cake in the oven quickly since this is single-acting and starts reacting immediately when wet. Baking powder provides the primary rise in most cakes. It creates the light, airy crumb that distinguishes cake from dense bread. Without enough leavening, cake will be flat, dense, and heavy. The substitute must produce sufficient gas for proper rise.
Best Substitute
Baking Soda + Cream of Tartar
1/4 tsp baking soda + 1/2 tsp cream of tartar per tsp of baking powder
This recreates baking powder exactly. Sift with the flour to distribute evenly. Get the cake in the oven quickly since this is single-acting and starts reacting immediately when wet.
What else can I use instead of baking powder in cake?
Baking Soda + Yogurt
1/4 tsp baking soda + 2 tbsp yogurt per tsp of baking powder
Yogurt adds moisture and tang. Reduce other liquids by 2 tbsp. Works excellently in chocolate and fruit cakes.
Whipped Egg Whites
2 whipped egg whites per tsp of baking powder
Fold into batter last. Creates an incredibly light, airy cake. Classic technique for angel food and chiffon cakes.
Club Soda (as liquid)
Replace some liquid with club soda (up to 1/2 cup per tsp of baking powder)
The carbonation adds lift. Mix gently and bake immediately. A quick fix in a pinch. Cake will be slightly less tall.

What happens if you forget baking powder in cake?
