Classic crumb cake is one of those deeply comforting bakes — tender, buttery cake blanketed in thick, cinnamon-scented clusters of golden topping — and this version delivers every bit of that cozy magic without a single egg in sight. The trick is a flax egg made by stirring ground flaxseed into water and letting it sit until it thickens into a gel, which binds the batter beautifully and keeps the crumb soft and moist. Whole milk, sour cream, and melted butter do the rest of the heavy lifting, giving the cake a rich, slightly tangy flavor that tastes anything but stripped down. Chilling the crumb topping while you mix the batter helps it hold together in those satisfying, chunky clusters that bake up deep golden brown and slightly crisp on top. The parchment overhang is a small but genius move — it makes lifting the whole cake out of the pan effortless, so your squares come out clean and picture-perfect. A dusting of powdered sugar right before serving is optional, but it adds a lovely finishing touch that makes this feel genuinely special. Cut into 9 squares, this is the kind of thing that disappears fast at a weekend brunch or afternoon coffee break.
