What's the difference between whipped butter and regular butter?
Whipped butter is aerated and lightened with milk and buttermilk, making it fluffier and easier to spread, while regular butter is denser and requires more force to spread.
Can I make whipped butter without buttermilk?
Yes, you can use all whole milk instead of the buttermilk-and-milk combination, though buttermilk adds a subtle tangy flavor that enhances the spread.
How long does whipped butter keep?
Store it in an airtight container in the refrigerator for up to 2 weeks. The texture will firm up when cold but softens quickly at room temperature.
Why does my whipped butter seem grainy?
This usually means the butter wasn't at room temperature when you started—cold butter doesn't incorporate smoothly. Always let butter soften to 65–70°F before whipping.
Can I scale this recipe up?
Yes, maintain the ratio of 4 parts butter to 1 part liquid (split between milk and buttermilk), and whip in batches if your mixer has limited capacity.
