and Schnitzel with noodles?
Well, Streusel is the thing on top of this cake (Streuselkuchen), while Strudel is the name for this dessert.
Streuselkuchen as well as Strudel come in all kinds of fruity varieties. Mmmm…Apfelstrudel.
Schnitzel with noodles?
Schnitzel usually comes with fries, unless it’s a Jägerschnitzel. In that case it has mushroom sauce on top and might come with Spätzle which I guess are noodles, but only technically speaking.
Streusel is a topping, made with butter (or other fat), flour, sugar, and spices.
Strudel is a pastry, made with thin sheets of pastry and usually with a fruit filling.
Schnitzel is a cutlet cooked in a coating, like Weiner Schnitzel is a veal cutlet coated with flour and spices, then fried.
So glad to help. Have a cookie.
I was kidding about the Schnitzel. Just tossed that in because of the song. (John Coltrane, you rule.) I had Wienerschnitzel once when I was a kid but now I’m vegetarian.
Now if only someone could explain the difference between blintz and blini.
Or kugel and Koogle™.
Jomo, I am going to smack you upside the head with a pan of kugel. Or a Koogle. Whichever.
Ginger, when you’re done smacking him, can I have the kugel? Huh? Pleeeeeeeeeeze? 
Blini are small pancakes, not much bigger than an old Eisenhower silver dollar, that serve as a perch for caviar (and less rarified hors d’oevres).
Blintzes are essentially crepes - much thinner than blini - that are filled with sweetened cheese (sometimes savory fillings, too), rolled up, fried again, and served with jam.
