⭐ Soy Milk + Lemon Juice or Vinegar (Best Dairy-Free Option)

1 cup soy milk + 1 tablespoon lemon juice or white vinegar

Quick tip: A dairy-free alternative that provides acidity and moisture similar to buttermilk, suitable for vegan diets.

Soy milk has a protein and fat content that can approximate cow’s milk, and when acidified with lemon juice or vinegar, it mimics buttermilk’s acidity. This activates baking soda for proper leavening and maintains dough hydration.

Let the mixture sit for 5-10 minutes before use to allow curdling and acidification. Use unsweetened soy milk to avoid altering the flavor profile.

Cinnamon rolls made with this substitute will have a slightly different flavor profile but maintain the desired tenderness and rise.

Coconut Milk + Lemon Juice or Vinegar

1 cup full-fat coconut milk + 1 tablespoon lemon juice or white vinegar

Quick tip: Adds richness and acidity but may impart a subtle coconut flavor and heavier texture.

Full-fat coconut milk provides fat and moisture similar to buttermilk, and acidification with lemon juice or vinegar supplies the necessary acidity to activate baking soda. This combination helps achieve tenderness and rise in the dough.

Because coconut milk is thicker and has a distinct flavor, it can slightly alter the taste and texture of cinnamon rolls. Use full-fat for best moisture and richness.

The final product may have a denser crumb and a mild coconut undertone, which might not be traditional but can be pleasant.
