The Home Economics Bit

The word streusel comes from the German word streuen, which means to scatter or sprinkle. A streusel is essentially a crumb topping that is commonly scattered over the tops of muffins, cakes, and pies. Streusel is typically made with flour, butter and sugar, and sometimes cinnamon. It gives baked goods a little extra texture and sweetness.
