Notes
Need more or less? Adjust as needed while keeping the 2:1:1 ratio for perfect results every time!
Test for Freshness: Drop a small amount into warm water. If it fizzes, it’s good to go.
Mix Well Before Using – Homemade baking powder can settle over time, so give it a quick whisk or shake before adding it to your recipe.
Bake Immediately – Since this is single-acting baking powder, it starts working as soon as it gets wet. Mix it in last and bake right away for the best rise.
No cream of tartar? Swap it with an acidic ingredient like lemon juice, vinegar, buttermilk, or plain yogurt.
Since these add liquid, you may need to slightly reduce the liquids in your recipe to keep the right consistency.
- Lemon Juice or Vinegar – Use 1 tsp per 1 tsp of cream of tartar.
- Buttermilk, Sour Milk, or Plain Yogurt – Use 1 cup per 1 tsp of cream of tartar.
