A simple, buttery crumble topping made from flour, sugar, and cold butter that bakes into a golden, crisp layer over any fruit pie. Perfect for apple, blueberry, or peach pies, this classic crumb topping adds sweet flavor and texture without the need for a top crust.
In the bowl of a stand mixer with the paddle attachment, combine the all-purpose flour, sugars, and salt. Give the mixture a quick stir to blend the dry ingredients evenly.
Add the cold, cubed butter and mix on low speed until the texture looks like wet sand and no large pieces of butter remain.
