Makes about 3 cups of whipped cream
1 cup heavy cream, chilled
1/2 cup plain yogurt, Greek or otherwise, full-fat or otherwise, chilled
In the bowl of a stand mixer fitted with a whisk, beat heavy cream and yogurt on medium-high speed until soft peaks form.
Alternately, you can use a hand mixer or whisk by hand. Taste and add more yogurt or cream to taste and whisk again to soft peaks.
