How to Make Butter at Home: The Complete Step-by-Step Guide

Butter is structurally simple: it is the fat separated from cream through mechanical agitation, washed to remove milk solids, and salted to taste. The entire process takes 10 to 15 minutes with a stand mixer or food processor, produces approximately 200g of fresh butter from 500ml of double cream, and results in a product that is meaningfully better than standard commercial butter in both flavour and texture. The reason is freshness: commercial butter is pasteurised, churned at scale, and may sit in cold storage for weeks before reaching a shop; homemade butter made from quality cream and used within a week is the freshest dairy fat most people will ever eat. It is also one of the most satisfying kitchen projects for the time invested, because the transformation from liquid cream to solid butter, which happens suddenly after several minutes of vigorous mixing, feels genuinely dramatic to observe.

What You Need

• 500ml double cream (minimum 36% fat; supermarket own-brand double cream works well; avoid single cream, which has insufficient fat)
• A stand mixer (KitchenAid whisk attachment), a hand mixer, or a food processor
• A fine mesh strainer or cheesecloth
• A bowl for catching buttermilk
• Cold water for washing
• Salt (flaked sea salt for the best texture; approximately 0.5 to 1 tsp per 200g butter)

Optional for cultured butter: a tablespoon of crème fraîche, yogurt, or cultured buttermilk stirred into the cream before churning, then left at room temperature for 12 to 24 hours to develop lactic acid fermentation.

The Method: Step by Step

Step 1: Temperature Matters

Remove the cream from the refrigerator 30 minutes before starting. Cold cream (straight from the fridge, 4°C) takes longer to churn and produces a firmer, slightly less flavourful butter. Room-temperature cream (18 to 20°C) churns faster and produces a more pliable, flavourful result. In a warm kitchen (over 22°C), cream may churn unevenly or the butter may become greasy; if the kitchen is warm, chill the bowl in the freezer for 10 minutes before starting.

Step 2: Whip to Whipped Cream, Then Keep Going

Pour the cream into the mixer bowl. Whip on medium-high speed. The cream will progress through several stages:

• Soft peaks (2 to 3 minutes): Cream thickens, holds a soft shape
• Stiff peaks (3 to 5 minutes): Whipped cream, fully formed
• Grainy/broken stage (5 to 8 minutes): The cream looks curdled and lumpy; do not stop here, this is normal
• Separation (8 to 12 minutes): Suddenly, butter solids clump together and yellow liquid (buttermilk) splashes in the bowl

Note: The separation stage is sudden. Cover the mixer with a damp tea towel before this point to prevent buttermilk splashing across the kitchen.

Step 3: Drain the Buttermilk

Pour the contents of the bowl through a fine mesh strainer into a second bowl. The liquid collected is real buttermilk (not the cultured product sold in shops, which is fermented skim milk). Save it: genuine buttermilk is excellent for pancakes, scones, bread, and marinades. The yellow solids remaining in the strainer are the butter.

Step 4: Wash the Butter

Washing is the step most home butter recipes skip, and it matters. Unwashed butter retains residual buttermilk in the fat, which causes the butter to go rancid within 2 to 3 days. Washing removes this residual milk: press the butter into a ball with your hands or a wooden spoon in the strainer, pour ice-cold water over it, and knead while the water runs milky white. Pour off the milky water and repeat with fresh cold water until the water runs clear (typically 3 to 4 washes). Washed butter will last 7 to 10 days in the refrigerator and up to 3 months in the freezer.

Step 5: Salt and Shape

Fold in flaked sea salt (0.5 to 1 tsp per 200g) while kneading. More vigorous kneading after salting produces a firmer, denser butter; less kneading produces a softer, flakier texture. Shape into a log using clingfilm or parchment paper, pressing firmly to eliminate air pockets, and refrigerate for at least 1 hour before slicing.

Cultured Butter

French-style cultured butter (beurre de qualité, Président, or Échiré are commercial examples) is made with fermented rather than fresh cream, which develops lactic acid and produces a more complex, tangy flavour. To make it at home: add 2 tablespoons of crème fraîche or natural yogurt to 500ml of cream, stir well, cover loosely, and leave at room temperature (18 to 22°C) for 12 to 24 hours. The cream will thicken and develop a slightly tangy scent. Then churn and wash as above. The result is a noticeably more complex butter with a background sourness and nuttiness that commercial unsalted butter lacks.

Clarified Butter and Ghee

Clarified butter (milk solids and water removed, leaving pure butterfat) is made by gently melting fresh butter in a saucepan over low heat until the foam (milk proteins) rises to the surface and the water boils off, leaving a clear golden liquid. Skim off the foam, then pour the clear fat through a cheesecloth-lined strainer, leaving the white milk solids behind. The clarified fat (ghee, if cooked a little longer until the milk solids turn golden and nutty) has a higher smoke point than whole butter (200 to 250°C vs 175°C), making it better for high-heat cooking. Ghee is shelf-stable for up to 3 months at room temperature.
