Necessary materials
The blueberry buckle ingredients are simple and easy to find (if you’re not already in the pantry). Below I have included notes and tips. Posting recipe cards will have a printable ingredient list and recipe details.
For toppings for breadcrumbs
Sugar – I use granulated sugar. Alternatively, you can use brown sugar for a more caramel flavor. Cinnamon – Feel free to replace the cinnamon for another warm spice, such as nutmeg, ginger, pumpkin pie spice. Also include salt in your recipe. Wheat Flour – All-purpose flour is perfect here. Butter – Mixed salted or unsalted butter in the microwave.
For the cake
Dry Ingredients – This is baking powder, salt for your flour, sugar, powder. Again, I recommend all-purpose flour for your cake. It gives you the most consistent results. Butter – this time at room temperature. If you forget to remove butter from the fridge in advance, an easy way to quickly soften the butter is to pour boiling water into a glass or ceramic bowl. After a few minutes, empty the water and place the bowl on top of the cold butter. It warms up and softens in about 10-15 minutes. Eggs and vanilla – Eggs can also be at room temperature. Milk – You can use whole milk, 2% milk, or any type you want. Even buttermilk (or homemade alternative) adds a nice layer of sparkling, like my strawberry buttermilk muffins. Blueberries – Use fresh blueberries when possible, but frozen works too (see below).
Can I use frozen blueberries?
yes! If you don’t have access to fresh blueberries for this recipe, you can use frozen blueberries instead. Thaw the blueberries completely and pat them before mixing the patting.

Make the cake dough. In a new bowl, whisk together the flour, baking powder and salt. Meanwhile, place the butter in the sugar, eggs and vanilla in another bowl. Slowly add the dry mixture to the wet ingredients and add the milk alternately until the milk is combined. Add blueberries. Next, gently fold the blueberries. Spread the batter into an oiled 9 x 9 inch baking pan.


Add the toppings. Use your fingers to break the crumble topping and sprinkle it over the cake batter. bake. Bake the blueberry buckle at 375ºF for 40-45 minutes, set in the center, and top with the golden color. Serve warmly and wait until the buckle cools to room temperature.

Baking tips and variations
Throw fresh blueberries in flour. It’s an extra insurance to prevent water-soaking buckle and also helps prevent berries from sinking to the bottom of the cake. Bake the frying pan. For rustic talent, the blueberry buckle is baked in an oven-bearing cast iron skillet. A simple add-in. Stir in fresh lemon zest to lighten the flavor, or use a mixture of blueberries, strawberries, raspberries and blackberries.

FAQ
They are all equally fruity desserts, but there are important differences. The buckle is similar to a coffee cake, but the cobbler is stuffed with baked blueberries underneath a layer of crispy batter. Similarly, what’s crispy is a filling of blueberry with crisp oat toppings.
The name comes from how the dessert is baked. The buckle rises in the oven as it is baked, then “buckle” or sinks under the weight of the crumble topping.

How to store a blueberry buckle
Keep it airtight. Store baked and cooled blueberry buckles at room temperature for up to 3 days or in the fridge. Warm it. If you want to enjoy the remaining slices warmly, microwave them for a few seconds before serving. Freeze. Alternatively, you can freeze this cake for up to 2 months. Thaw the buckle in the fridge or thaw at room temperature when ready to serve.
