Blueberry Buckle



Blueberry Buckle

This classic Blueberry Buckle is the blueberry coffee cake of my dreams! The cake itself has got such a soft and tender crumb and it’s brimming with fresh, sweet, juicy blueberries, then it’s covered with a delicate yet perfectly crisp, cinnamony crumble that will make your heart sing. This is a cake you don’t want to miss out on!

This cake is so good in fact I’d be totally fine with having this as my birthday cake – even though there’s no frosting! Blueberry desserts are totally my thing and I love that this will pass for either breakfast or dessert :). And that generous amount of fresh blueberries in this cake takes it over the top. Blueberries in every bite!

Blueberry Buckle

A few tips for this recipe, be gentle with the batter so it’s not a super dense cake (it’s not a super fluffy cake but over-working the batter will make it more dense than it’s intended to be). It is a thick batter to fold but I think folding the flour in by hand does make a difference. Then also you do want fine crumbs for the topping so it’s light, this helps keep them from sinking into the center of the cake as it bakes. Those tiny buttery crumbs are definitely a highlight of this cake!

Now go grab some fresh summer blueberries while they’re in season and while they’re on sale and make this heavenly Blueberry Buckle!

Servings: 12


Crumb topping

  • 6 Tbsp (56g) all-purpose flour
  • 1/3 cup (66g) granulated sugar
  • 1 tsp ground cinnamon
  • 1 pinch salt
  • 1/4 cup (56g) unsalted butter, cold and diced into cubes


  • 1 3/4 cups (247g) all-purpose flour (use scoop and sweep method to measure)
  • 2 tsp baking powder
  • 1/2 tsp salt
  • 1/2 cup (113g) unsalted butter, softened
  • 3/4 cup (150g) granulated sugar
  • 1 large egg
  • 1 tsp vanilla extract
  • 1/2 cup (120ml) milk (anything but skim)
  • 2 cups (290g) fresh blueberries


For the topping:

  1. Preheat oven to 375 degrees. Add flour, sugar, cinnamon and salt to a food processor and pulse several times. Add in butter and pulse until mixture appears sandy with tiny bits of butter. Transfer to refrigerator and chill while preparing cake.

For the cake:

  1. Butter a 9 by 9-inch baking dish. Line with parchment paper and butter parchment paper, set aside. In a mixing bowl whisk together flour, baking powder and salt, set aside.

  2. In the bowl of an electric stand mixer fitted with the paddle attachment cream butter and granulated sugar until pale and fluffy. Mix in egg and vanilla. Remove bowl from stand mixer (scrape excess butter on paddle into bowl). Add 1/2 of the flour mixture (to sugar/egg mixture) and fold just nearly until combined then add in 1/2 of the milk and fold just until nearly combined, repeat process with flour and milk once more, then add in blueberries and fold just to evenly distribute. 

  3. Pour batter into prepared pan and spread into an even layer. Remove crumble from refrigerator and sprinkle evenly over top. Bake in preheated oven until toothpick inserted into center comes out clean (center also shouldn't fall when lightly pressed), about 30 - 35 minutes. Let cool at least 5 minutes then lift from pan using parchment. Cut into squares and serve warm. Store in an airtight container.

  • Melissa: I have a bag of frozen blueberries in my freezer. Would this recipe work with frozen berries and how should I use them? July 27, 2017 at 1:01pm Reply

    • Jaclyn: Yes frozen would work as well. I’d fold them in frozen so the batter doesn’t go gray. Then you’ll have to add maybe 10 mins to baking time. July 27, 2017 at 8:08pm Reply

  • Heghineh: This recipe looks so appetizing! My kids love blueberry muffins, they will LOVE this! Thank you for sharing :) July 27, 2017 at 2:05pm Reply

  • Laura L: Have you thought of using the crumb topping that you use on your crumb cake for this recipe? It’s so delicious. July 27, 2017 at 2:13pm Reply

    • Jaclyn: Yes I do love that one too but I thought I’d change it up a little and go with a finer, more cinnamony crumb here :). July 27, 2017 at 8:36pm Reply

  • joan: Your pictures are wonderful, yum yum!

    When I make the cake I will use almond flour, do you think that’s okay?
    Love your blog…. July 27, 2017 at 7:47pm Reply

    • Jaclyn: I’m not sure how it would turn out with almond flour, I rarely bake with it (mostly just macarons). Not sure how well the cake would hold together. When experimenting I’d probably go with half all-purpose and half almond flour and probably just research online substituting almond flour for all-purpose flour and you may find what you’re looking for. Hope that helps and I’m so happy to hear you love my blog Joan :)! July 27, 2017 at 8:36pm Reply
