Creaming simply means mixing your butter and sugar(s) together until well blended, leaving you with a fluffy light yellow mix. Just do not over mix!
Can you cream with a whisk?
Use an electric whisk on its slowest speed initially, then increase the speed to create a light and fluffy mixture. Stop whisking occasionally to scrape the mixture down from the sides of the bowl back into the middle, then continue whisking. When the mixture is pale and airy it's ready to use in your recipes.
