Step 1

Melt the butter and let it slightly cool.

Step 2

In a small bowl combine the flour, sugar, and salt and use a fork to whisk it together.

Step 3

Drizzle the melted butter over the flour mixture and use a fork to combine it into a coarse crumb.

Step 4

As the streusel sits it will stiffen up and be easy to crumble with your fingers. If it's too soft, pop it in the fridge for 5 minutes.

Step 5

Generously pile the crumble topping on top of the muffins, cake, or quick bread.
