"Crisp fall apples, tossed in cinnamon and baked with delicious streusel. Almost as good as pie, with half the calories and it's in the oven in 10 minutes! Plus, it can be served warm with ice cream, and the smaller size means it won't be there to tempt you later. Enough for a small mini casserole dish that will serve 3-4 people. Double the recipe for an 8x8 pan, quadruple it for a 9x13 pan".
Unless you double the batch and use a bigger pan, in which case, it's a great breakfast topping for oatmeal! Enjoy!
Adapted from Penzey's spices and the intro is what they said about the recipe.
A little history:
In baking and pastry making, the term streusel (a German word meaning "something scattered or sprinkled", from the verb streuen, akin to the English verb 'strew') refers to a crumb topping of butter, flour, and white sugar (traditional German) that is baked on top of muffins, breads, and cakes (e.g. Streuselkuchen). Some modern recipes add various spices and occasionally chopped nutmeats. Although the topping is of German origin, it is sometimes referred to as Danish or Swedish.
