How do I substitute baking powder in pancake and waffle batter?
Use Baking Soda + Cream of Tartar at 1/4 tsp baking soda + 1/2 tsp cream of tartar per 1 tsp baking powder — This is essentially homemade baking powder. Single-acting only. Mix as the original recipe directs, then taste and adjust liquid or bake time in small steps after a test batch.
