Streusel is a sweet, crumbly topping for baked goods. If you're not a fan of pie crust, you might prefer pies with streusel on top. Yum!
Typically, streusel is made with butter, flour, and sugar, sometimes with added ingredients like oats, spices, or nuts. Besides pies, sweets that often have a streusel topping include coffee cake, muffins, cakes, and fruit crisps. In German, Streusel means "something scattered or sprinkled," which is exactly what a baker does with streusel before baking.
