Got extra blueberries to use up? Our classic Blueberry Cobbler is another fantastic home for them.

Years ago, practically in another lifetime, I visited Pennsylvania where my ex-boyfriend’s mother lived. She took us blueberry picking and our bounty ended up in a few desserts, including a Blueberry Buckle. I’ve never forgotten it.

Easy Blueberry Buckle Cake

Have you ever had a blueberry buckle? It’s an old fashioned single-layer blueberry cake with a dense batter, but a tender crumb and a streusel topping. It’s as if a blueberry muffin and coffee cake got married. The cake gets its name from how it bakes – as the batter rises, the berries and streusel weigh it down, causing the top layer to buckle and give it an indented look.

While a blueberry buckle and a blueberry cobbler are both fruit desserts, there is a difference. Cobblers have fruit on the bottom and are typically baked with a biscuit-style topping, whereas a buckle has a streusel topping and a batter and fruit are mixed and baked together to form a cake.

Blueberry Buckle Recipe

This Blueberry Buckle recipe is the one I adore from over two decades ago and my absolute favorite. With a buttery, soft crumb and sweet, juicy blueberries throughout, then finished with a sweet crisp cinnamon crumble, every bite is glorious! Bonus: Great for dessert, of course, but also perfectly acceptable served for breakfast with a cup of coffee!

Here’s what you’ll need to make it:
(Scroll below to the printable recipe card for details and measurements.)

• Blueberries: Fresh or frozen blueberries can be used (see notes below.)
• Batter: Granulated sugar is blended together with shortening and butter. Mixed with egg, lemon zest, vanilla, milk, flour, baking powder, and kosher salt. The batter will be thick that needs to be spread, not poured, in the baking dish. The end result is a dense, but moist cake.
• Topping: The topping for this buckle is a traditional streusel consisting of flour, granulated and brown sugar, cinnamon, and butter.

Fresh or Frozen Blueberries

There’s nothing like plump, juicy fresh summer blueberries, but frozen blueberries work well in this cake, too. I often buy fresh blueberries when they’re in season and freeze them for later. If using frozen berries, do not thaw them first to avoid discoloring the batter, and gently fold them in. You’ll likely need to increase the baking time by 5-10 minutes. Watch the cake and tent with foil if the topping is over-browning.

Recipe Variations

• Use a different berry: This recipe works well with almost any other fruit. Try small raspberries or blackberries, chopped up peaches or strawberries. Delish!
• Double the recipe: Feeding a crowd and need extra cake? You can double all the ingredients and bake it in a 9×13 pan. It should cook for the same amount of time, but all ovens run differently. It’s finished cooking when a toothpick inserted in the center comes out clean.
• Make muffins instead: This blueberry buckle cake recipe can be converted into muffins. Fill lined muffin tins 3/4 way full, top with the streusel, then bake for 18-20 minutes or until a toothpick in the center comes out clean.

Tips for Success

• Measure the flour correctly: Spoon and level, don’t scoop. Too much flour will lead to a dry cake.
• Make the streusel topping first and chill: Prepare the streusel and place it in the fridge, while you make the cake batter. Chilling it, then breaking it into pea size crumbles will result in a nice crunchy topping.
• Use butter and shortening: A 50/50 ratio of butter and shortening will produce the most tender, soft crumb.
• Don’t over-work the batter: This is a dense cake where the batter doesn’t rise very much, but it should still be moist and tender. Over-working the batter will make it even more dense.

Proper Storage

Blueberry Buckle is wonderful warm right from the oven, but leftovers store really well.

• To Store: Store leftover cake, covered, at room temperature for up to 4 days.
• To Freeze: Allow baked cake to cool completely, then store in an airtight freezer-safe container in the freezer. It will keep for 2 months. You can freeze it whole or individually wrapped slices. If thawing the entire cake, let it sit in the fridge overnight. If thawing a single slice, it can just thaw on the counter. NOTE: The streusel topping will lose its crispness after being frozen.
