Sour Cream Coffee Cake, with a Ridiculous Amount of Streusel from The Food Charlatan. This is my FAVORITE recipe for Sour Cream Coffee Cake! My main complaint with Coffee Cake is that there is usually too much cake, not enough streusel. This recipe gives you the max amount of streusel without ruining the light fluffiness of the cake! A vanilla drizzle finishes it off! #coffeecake
