Being a dairy-free blogger, I’m always trying to figure out how to make my baked goods and recipes taste like the real deal. And that includes making a homemade dairy-free buttermilk substitute!

Ingredients Needed

  • Vinegar: you can use white vinegar, apple cider vinegar, white wine vinegar or even lemon juice!
  • Milk: feel free to use your favorite dairy-free milk. I have noticed some curdle better than others though and find that soy milk and almond milk work best. In a pinch, you can use oat milk!

Step by Step Instructions

Step 1: Measure the milk out into a cup, bowl, or jar. Add the vinegar or lemon juice and whisk together.

Step 2: Set aside for 3-5 minutes until it has curdled. Some types of milk won’t curdle as much as others, but that’s ok! It’ll still work in your recipe.

Step 3: Use right away or store in the fridge for up to 3 days.

Expert Tips

  • This recipe makes 1 cup of buttermilk, so you might need to double the ingredients depending on the recipe you’re using.
  • Feel free to use any vinegar you’ve got in your pantry! You can try this with apple cider vinegar, white wine vinegar, white vinegar or even lemon juice. We need something acidic to curdle the milk.
  • I have found certain types of dairy-free milk curdle better than others. If your milk doesn’t curdle that much, don’t worry! It’ll still work in your recipe.
  • What I love about this dairy-free buttermilk recipe is I can freeze it! Just freeze it in ice cube trays, then once frozen store it in a ziploc bag for up to 2 months.

Storage Instructions

If you’re not using it right away, store covered in the fridge for up to 3 days. To freeze, freeze in ice cube trays and then store in a ziploc bag for up to 2 months.
