Knowing how to make a great (and quick!) Crumble Topping is one of the best skills an at-home chef can have. The possibilities are endless!
Add the flour, brown sugar, granulated sugar, cinnamon (if using), and salt to a medium-sized bowl. Whisk to combine.
Scatter the butter across the top of the mixture. Rub the butter into the flour mixture using your fingertips until it is well-mixed and no longer appears dry.
