This tender, tall-rising cake gets its plush crumb from a good long beat of sugar and softened butter, with room-temperature eggs and full-fat sour cream folding in to keep every bite moist and rich. The streusel layer is where the magic happens: brown sugar, cinnamon, and flour clump into coarse, buttery crumbs that turn deep golden and just barely crisp on top while staying soft underneath. A sweet vanilla glaze gets drizzled over the whole thing while it's still warm, soaking slightly into the crumbs for extra flavor in every square. Baked in a 9x13 pan and served straight from it, this is an easy make-and-share dessert or brunch centerpiece with zero fuss involved. Since there's no meat or fish anywhere in this recipe, it's a naturally solid fit for a vegetarian table and easy to bring to a potluck without a second thought. Cinnamon-sugar crumb topping and a soft, buttery cake underneath make this one worth keeping on repeat.
