I have a basic crumb topping that I use to top fruit crumbles. It consists of 1 cup brown sugar, 1 cup flour, and 1/2 cup margarine. I like to make it in big batches and freeze in individual bags in the freezer so that I can just pull it out and sprinkle it on top of the fruit whenever I need it. The trouble is that the recipe calls for it to be made by hand, and I really really dislike making it... My hands end up hurting badly for a while after, and it takes a long time to get the margarine off.
Can I make it in a stand mixer or would that affect the quality? I would probably use a cookie paddle to mix it.
