Credit, first and foremost, to my friend Rebecca for introducing me to this cake. Blueberry buckle is her favorite cake, and I and others have made it for her birthday. It is, in my opinion, one of the highlights of American baking. The recipe itself originated in Colonial New England as an adaptation of an English cake, and uses a native ingredient – blueberries. That said, this recipe is much like smetanakuchen, the coffee cake introduced by Ashkenazi Jews with great success to the Northern United States. And though I love Jewish coffee cake, the blueberry buckle has a moisture that the cake is sometimes missing. The name itself comes from the fact that the crumb topping causes the cake to “buckle” – as you can see in the picture.
I made the buckle a little softer than most buckles, because I find that the melty blueberry goes well with that texture. You can totally use frozen blueberries if that is easier or more affordable for you, or if you prefer the result. I added some yogurt to give the cake more weight.
4 tablespoons salted butter, melted
½ cup full-fat Greek yogurt, at room temperature
½ cup whole milk
¾ cup brown sugar
1½ cups flour
2/3 teaspoon baking soda
2 cups fresh or frozen blueberries
4 tablespoons salted butter, softened
½ cup white sugar
1/3 cup flour
1 tsp ground cinnamon
- Preheat the oven to 375F/190C. Grease a cake pan – I used a 9”/23cm wide round pan, but you can use a similarly sized square pan.
- Whisk together the butter, yogurt, milk, sugar, and eggs until thoroughly combined. Add the flour and baking soda and mix in thoroughly.
- Fold in the blueberries until evenly distributed through the batter. Then, pour the batter into the greased pan.
- With a pastry knife, fork, or food processor, blend the topping ingredients together. Then, sprinkle on top of the cake.
- Bake for 35-45 minutes or until a toothpick in the cake comes out clean. Let cool before serving.
Thank you to Rebecca Galin for introducing me to this cake.
