Some recipes just feel like home—and this one is no exception.

Passed down from our own grandmother’s kitchen, this brown sugar crumb cake is tender, buttery, and topped with just the right amount of nutmeg-spiced crumble. The secret? A splash of buttermilk (or a quick DIY swap) that keeps every bite irresistibly moist. It’s simple, cozy, and best served warm – preferably with a cup of coffee and a little nostalgia.

Kitchen Tip

You can substitute buttermilk by adding 1½ tablespoons of vinegar or lemon juice to regular milk and letting it sit for a few minutes before using.
