The crumble topping—streusel—is a stroke of genius, says chef Johnny Gnall. A few basic ingredients, mashed together by hand and popped into the oven, results in a sweet, rich, crumbly voluptuousness that’s wonderful with any number of sweets. It’s a low fuss, crowd-pleasing dessert topping that can really dress things up.
Crumble topping, known in German as streusel (SHTROY-zul,) is a crumb topping of butter, flour and sugar; it can contain chopped nuts or rolled oats. The word derives from the German “streuen,” meaning to sprinkle or scatter. Streusel is used as a topping for a variety of pies, fruit crisps, cakes and pastries, most notably coffee cakes. A pie with a streusel topping is sometimes referred to as a “crumble pie.”
The best thing about a crumble topping is its versatility.

In this recipe, made with whole wheat flour and golden brown sugar, oats add a pleasant heartiness—plus, they’re a second whole grain. You can substitute white flour and hold the oats; but you’ll get much more flavor as shown.
2. Once all of the dry mix is incorporated into the butter, spread out on a cookie sheet or baking tray topped with a piece of parchment paper. Bake at 350°F for 30 minutes. For a crispier crumble you can bake longer, but you may prefer it on the softer side, especially with baked apples.
CRISP, CRUMBLE, COBBLER: WHAT’S THE DIFFERENCE?
Crisp. A crisp is a deep-dish fruit dessert made with a crumb or streusel topping and baked. A betty is a crisp topped with buttered bread crumbs or bread pieces instead of streusel; “brown” (as in apple brown betty) refers to the brown sugar in the recipe.
Crumble. Crumble is the British term for a crisp.
Cobbler. A cobbler topping is different from a crisp or crumble, which has a crumb topping. Shortcake batter or biscuit dough is dropped onto the fruit before baking. The dish got its name because the lumps of cooked dough resembled cobblestones. Related desserts include a grunt, which is a spoon pie with biscuit dough on top of stewed fruit (fruit which is steamed, not baked); a pandowdy, a spoon pie with a rolled top crust that is broken up to allow the juices to come through; and a slump, a spoon pie topped with biscuit dough or pie crust, which can be baked or steamed, and can be made upside down.
