How It Works

How to Make Dairy-Free Substitutions

General Rules

  • Milk: Replace 1:1 with oat milk, almond milk, soy milk, or coconut milk
  • Heavy cream: Use full-fat coconut cream or cashew cream
  • Buttermilk: Add 1 tbsp lemon juice or vinegar to 1 cup non-dairy milk
  • Sour cream: Use coconut cream or cashew-based sour cream
  • Butter: Use vegan butter or coconut oil

    • Notes

    Soy milk and oat milk are closest to dairy milk in protein and cooking behavior. Nut milks are lower in protein.

    Worked Example

    Replace 250 mL of whole milk with a dairy-free option.

    dairy_amount_ml = 250dairy_type = 1
    1. 01Use 250 mL of any plant milk (1:1 ratio).
    2. 02Oat milk is closest in creaminess and body.
    3. 03Calorie difference with almond milk: 250 x (0.17-0.42) = -62.5 kcal saved.

    Frequently Asked Questions

    Which plant milk is best for baking?

    Soy milk and oat milk work best due to their protein content and neutral flavor. Coconut milk adds richness but may impart coconut flavor.

    Can I use water instead of milk?

    In some recipes, yes, but the result will be less rich and tender. If using water, add a tablespoon of oil per cup to compensate for fat.

    How do I make dairy-free buttermilk?

    Add 1 tablespoon of lemon juice or white vinegar to 1 cup of plant milk. Stir and let sit 5 minutes until it curdles slightly.
