Homemade Buttermilk is a quick and easy substitute for store-bought buttermilk, using just two ingredients. Ideal for baking recipes that call for buttermilk, it helps provide moisture and tenderness to baked goods.

Ingredients

Scale
  • 1 tablespoon lemon juice or white vinegar
  • 1 cup milk (preferably whole milk)

Instructions

  1. Pour the lemon juice or vinegar into a measuring cup.
  2. Add milk to the 1-cup line and stir to combine.
  3. Let the mixture sit at room temperature for 5–10 minutes, until it thickens slightly and curdles.
  4. Use as a substitute for 1 cup of buttermilk in recipes.

Notes

  • This recipe can be scaled up or down depending on your needs.
  • Use whole milk for the richest results, but 2% also works.
  • Do not use plant-based milk unless it can curdle (like soy or oat with vinegar).
  • Best used fresh, but can be stored in the fridge for up to 3 days.
