Blueberry Buckle is what I'd call a timeless dessert, and this recipe is a solid version. It has a buttery cake base, sweet pockets of fresh blueberries, and a crunchy streusel topping. It's an old-fashioned dessert that feels both nostalgic comforting. This is an old photo which I tried to enlarge. I'll take a new one soon, but this gives you an idea of what it looks like.

A Bit of History
Blueberry Buckle dates back to at least the early 20th century. It often appeared in community cookbooks and farmhouse kitchens as a way to highlight seasonal berries. Cousin to other rustic fruit desserts like cobblers, crisps, and crumbles, buckles are unique in that they start with a cake batter. Also, the name "buckle" refers to the way the cake batter rises and "buckles" around the fruit and topping as it bakes. The result is a moist cake with a jammy blueberry layer and a sweet, crisp crumble on top.
Baking Tips for the Best Buckle
- Use Fresh or Frozen Blueberries: If using frozen, don't thaw them. Just toss them with a spoonful of flour to prevent sinking and excess moisture.
- Don't Overmix the Batter: Stir until just combined for a tender crumb. Overmixing can make the cake dense.
- Streusel Matters: A good buckle has a generous layer of buttery streusel. Make sure your topping is well mixed and crumbly before sprinkling over the batter.
- Pan Size: Most buckles are baked in an 8 or 9-inch square pan, but you can also use a round cake pan or even a springform for a prettier presentation.

We made a blueberry coffee cake for TWD a while back and this looks similar and was SO good. I've been loving this blueberry season, so I'll have to give this a try. Great pick and nice post, Sue.
