Ever started baking only to realize you’re out of buttermilk? It’s a common kitchen dilemma. The good news is that learning how to make buttermilk at home is incredibly simple and takes just a few minutes. Whether you’re preparing fluffy pancakes, tender biscuits, or marinated fried chicken, homemade buttermilk works just as well as store-bought.
In this guide, you’ll discover how to make buttermilk from milk, plus two popular alternatives — how to make buttermilk with vinegar and how to make buttermilk with lemon juice. Let’s break it down step-by-step.
What Is Butter milk?
Traditional buttermilk was the liquid left after churning butter. Today, most store-bought versions are cultured buttermilk, made by adding lactic acid bacteria to milk. This gives it a tangy flavor and slightly thick texture.
Homemade buttermilk mimics this acidity using simple ingredients you already have.
How to Make Butter milk From Milk

Instructions

- Add 1 tablespoon of vinegar or lemon juice.
- Stir gently.
- Let it sit for 5–10 minutes.
- Once slightly thickened and curdled, it’s ready to use.
That’s it! You’ve successfully learned how to make buttermilk from milk.
How to Make Butter milk With Vinegar
White vinegar is one of the easiest ways to create a buttermilk substitute.
Steps
- Add 1 tablespoon white vinegar to a measuring cup.
- Fill the cup with milk until it reaches 1 cup.
- Stir and let it sit for 5–10 minutes.
Why It Works
The acidity in vinegar reacts with the milk, creating the tangy flavor and texture typical of buttermilk.

Lemon juice provides a fresh flavor and works perfectly in baked goods.
Steps
- Add 1 tablespoon fresh lemon juice to a cup.
- Fill with milk to reach 1 cup total.

This method is ideal for pancakes, cakes, and muffins.
Tips for Best Results

These alternatives still provide the acidity needed for baking.
