This Homemade Baking Powder recipe is a simple and quick way to make your own fresh and effective baking powder substitute using just baking soda, cream of tartar, and cornstarch.

Ingredients

Small Batch Ingredients

  • 1 tsp Baking Soda
  • 2 tsp Cream of Tartar
  • 1 tsp Cornstarch or Arrowroot Powder

Larger Batch Ingredients

  • 4 tbsp Baking Soda
  • ½ cup Cream of Tartar
  • 4 tbsp Cornstarch or Arrowroot Powder

Instructions

  1. Measure Ingredients: Accurately measure the baking soda, cream of tartar, and cornstarch or arrowroot powder using teaspoons for small batch or tablespoons and halves cups for larger batch.
  2. Mix Thoroughly: Combine all ingredients in a mixing bowl and stir well with a spoon, breaking up any lumps to ensure a smooth, even mixture.
  3. Store Properly: Use a funnel to transfer the mixture into an airtight container to keep it fresh and protected from moisture.
  4. Use as Needed: Substitute this homemade baking powder in your recipes just like you would store-bought baking powder, measuring the same amounts.

Notes

  • For best results, store your homemade baking powder in a cool, dry place.
  • The cornstarch or arrowroot powder helps absorb moisture and keep the mixture dry.
  • Make small batches to ensure freshness, as homemade baking powder may lose potency over time.
  • Use within 3 months for optimal leavening power.
  • If you don’t have arrowroot powder, cornstarch is a great alternative and vice versa.
