What You’ll Need
This recipe uses simple, readily available ingredients, so you’ll likely have most of them already in your pantry. Let’s get started!
- Fresh Blueberries (3 cups): The star of the show! Use fresh, ripe blueberries for the best flavor and juicy texture. Frozen blueberries will work in a pinch, but be sure to thaw and drain them thoroughly before adding them to the batter.
- All-Purpose Flour (2 cups): Provides the structure for our delicious buckle.
- Granulated Sugar (1 ½ cups): Sweetness balanced perfectly with the tart blueberries.
- Baking Powder (2 teaspoons): The leavening agent for a light and fluffy buckle.
- Baking Soda (½ teaspoon): Helps create a tender crumb.
- Salt (½ teaspoon): Enhances the overall flavor.
- Unsalted Butter (½ cup, softened): Adds richness and flavor to both the cake and streusel topping.
- Eggs (2 large): Bind the ingredients together and add moisture.
- Milk (1 cup): Adds moisture and tenderness to the cake.
- Vanilla Extract (1 teaspoon): A touch of classic flavor.
- Lemon Juice (1 tablespoon): Brightens the overall flavor profile.
- Brown Sugar (½ cup, packed): For a deeper, richer flavor in the streusel topping.
- Ground Cinnamon (½ teaspoon): A warm spice that complements the blueberries beautifully.
- Oatmeal (½ cup, quick-cooking): Adds texture to the streusel.
Step-by-Step Instructions
Let’s bake this amazing blueberry buckle! Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan. This prevents sticking and ensures easy removal.
Step 1: Prepare the Batter: In a large bowl, whisk together the flour, granulated sugar, baking powder, baking soda, and salt. In a separate bowl, cream together the softened butter and sugar until light and fluffy. Beat in the eggs one at a time, then stir in the milk and vanilla extract. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix!
Step 2: Fold in the Blueberries: Gently fold in the blueberries. Don’t be afraid to get your hands in there! It’s a great way to ensure the blueberries are evenly distributed throughout the batter. Avoid overmixing at this stage as it can crush the blueberries.
Step 3: Make the Streusel Topping: In a medium bowl, combine the brown sugar, cinnamon, oatmeal, and melted butter. Use your fingers to crumble the mixture until it resembles coarse crumbs. This is the fun part – get creative with the texture!
Step 4: Assemble and Bake: Pour the blueberry batter into the prepared pan. Sprinkle the streusel topping evenly over the batter. This is where the magic happens!
Step 5: Baking Time: Bake for 35-40 minutes, or until a wooden skewer inserted into the center comes out clean. Keep an eye on it during the last 10 minutes – ovens vary, so you might need to adjust baking time slightly. If the top starts browning too quickly, loosely cover it with foil.
Step 6: Cooling and Serving: Let the buckle cool in the pan for at least 10-15 minutes before serving. This allows it to set slightly, making it easier to cut and serve. Serve warm or at room temperature. Enjoy!
Tips for Success
To achieve the perfect blueberry buckle every time, consider these helpful tips: Don’t overmix the batter – overmixing can lead to a tough buckle. Gently fold in the blueberries to prevent crushing. Make sure your butter is softened but not melted – this ensures proper creaming and a tender crumb. Don’t be shy with the streusel topping – it adds so much flavor and texture. If you find your buckle is browning too quickly, cover it loosely with aluminum foil during the last part of the baking process. Lastly, let the buckle cool slightly before cutting and serving – this prevents it from crumbling.
Variations to Try
Feel free to experiment with this recipe! Add a handful of chopped pecans or walnuts to the streusel for extra crunch. For a lemon blueberry buckle, add the zest of one lemon to the batter. If you prefer a spicier buckle, add a pinch of nutmeg or allspice to the streusel. To make a gluten-free version, substitute all-purpose flour with a gluten-free blend. For a vegetarian version, ensure that your butter is dairy-free or use a vegan alternative.

Storing and Reheating
Store leftover blueberry buckle in an airtight container at room temperature for up to 3 days. For longer storage, you can freeze the buckle for up to 2 months. To freeze, wrap the cooled buckle tightly in plastic wrap, then place it in a freezer-safe bag. To reheat, let the buckle thaw overnight in the refrigerator, then reheat individual slices in the microwave for 30-60 seconds or in the oven at 350°F (175°C) for 10-15 minutes. While reheating, be mindful not to overcook, which can dry out the buckle. Enjoy your delicious blueberry buckle fresh or reheated!
