History
While it’s unclear exactly when blueberry crumble cake squares first appeared, many believe they emerged as a delightful twist on traditional British crumbles during the early 20th century. As you explore their history, you’ll discover that these treats blend the juicy, tart flavors of blueberries with a rich, buttery crumble, making them a beloved dessert across various cultures.
Initially, British crumble recipes didn’t include blueberries. However, with the fruit’s increasing availability, particularly in North America, creative bakers began experimenting by adding blueberries to their crumbles.
The innovation didn’t stop there. As these crumbles gained popularity, the idea to encase them in a cake-like form took shape, leading to the invention of the blueberry crumble cake square.
This adaptation was likely influenced by the American penchant for portable and convenient desserts, combined with an affection for fruit-based sweets. Blueberry crumble cake squares became a fixture at gatherings and picnics, offering a comforting taste of home baking melded with the ease of slicing and serving.
Your appreciation for these delightful squares might deepen when you consider their historical journey — from simple fruit crumbles to a refined, shareable treat that brings smiles at today’s tables.
Recipe
Enjoy the delightful blend of savory and sweet with these Blueberry Crumble Cake Squares, perfect for any occasion. Whether it’s a warm summer morning or a chilly winter afternoon, the tartness of the blueberries combined with the sweetness of the crumble topping creates a perfect balance.
This treat not only pleases the palate but is also visually appealing with its vibrant berry bursts and golden topping.
This recipe is straightforward, making it an excellent option for bakers of all skill levels. The base of the square is a soft, moist cake, topped with fresh blueberries and a crumbly, buttery topping. The result is a deliciously satisfying snack that pairs wonderfully with your favorite tea or coffee, or as a stand-alone treat.
Ingredients:
- 1 1/2 cups all-purpose flour
- 1/2 cup granulated sugar
- 1/4 teaspoon salt
- 1/2 teaspoon baking powder
- 1/2 cup unsalted butter, softened
- 1 egg, beaten
- 1 teaspoon vanilla extract
- 2 cups fresh blueberries
- 1 tablespoon cornstarch
- 2 tablespoons fresh lemon juice
For the crumble topping:
- 1/2 cup brown sugar
- 1/3 cup all-purpose flour
- 1/2 teaspoon ground cinnamon
- 1/4 cup unsalted butter, chilled and diced
Cooking Instructions:
Start by preheating your oven to 375°F (190°C) and greasing a 9-inch square baking dish. In a medium bowl, whisk together flour, sugar, salt, and baking powder.
Cut in the softened butter until the mixture resembles coarse crumbs. Stir in the beaten egg and vanilla extract until a dough forms. Press the dough evenly into the prepared baking dish.
In another bowl, toss the blueberries with cornstarch and lemon juice, then spread them over the crust. For the crumble topping, combine brown sugar, flour, and cinnamon in a bowl.
Cut in the chilled butter until the mixture is crumbly. Sprinkle this evenly over the blueberries. Bake for 35-40 minutes, until the top is golden and the blueberries are bubbly. Allow to cool before cutting into squares.
Extra Tips:
For the best results, use fresh, firm blueberries to avoid too much juice, which can make the base soggy. If using frozen blueberries, don’t thaw them as they can release excess moisture.
Also, verify your butter is properly chilled for the crumble topping; this helps achieve that delightful, crispy texture. Let the squares cool completely in the dish before cutting, as this helps them set and makes them easier to serve neatly.
For an extra touch of flavor, serve with a dollop of whipped cream or a scoop of vanilla ice cream.
Step 1. Mix Blueberry Batter Ingredients
Start by gathering all the necessary ingredients for your blueberry batter. You’ll need fresh blueberries, all-purpose flour, granulated sugar, baking powder, a pinch of salt, unsalted butter, eggs, and milk. Confirm your ingredients are at room temperature to achieve a smooth, even mix.
First, combine your dry ingredients. In a medium-sized bowl, whisk together about two cups of flour, a teaspoon of baking powder, and your pinch of salt. This mixture will help your cake squares rise and provide the desired fluffy texture.
Next, focus on the wet ingredients. In another bowl, cream together the butter and sugar until the mixture is light and fluffy. This step is vital; it incorporates air into the batter, which contributes to the lightness of the cake.
Beat in the eggs one at a time, making sure each is fully integrated before adding the next. Stir in a teaspoon of vanilla extract for an extra layer of flavor.
Now, alternate adding the dry ingredients and milk to the creamed butter mixture, starting and ending with the dry. Stir just until the ingredients are combined; overmixing can make the batter tough.
Gently fold in the blueberries last to prevent them from bursting and turning your batter entirely blue.
Step 2. Pour Batter Into Pan
After folding the blueberries gently into your batter, you’re ready to prepare it for baking. Start by grabbing your pre-greased baking pan. You’ve likely chosen either an 8×8 inch or 9×9 inch pan, which are ideal sizes for guaranteeing even cooking and perfect portioning of your cake squares.
Now, pour the batter into the pan. It’s important to do this steadily and evenly; you want the distribution of blueberries throughout the cake to be as uniform as possible. Use a spatula to help scrape the batter from the sides and bottom of your mixing bowl – you don’t want to waste any of that delicious mixture.
Once all the batter is in the pan, take a few moments to smooth the top with your spatula. This doesn’t just help with aesthetics; it also guarantees that your cake layers beautifully and cooks evenly.
Finally, give the pan a gentle tap on the counter. This helps to remove any air bubbles that might’ve formed during the mixing and pouring process. Eliminating these bubbles will help prevent any unsightly holes in your finished cake, ensuring a smoother, more professional appearance.
Now, with your batter set and smoothed, you’re all set for the next step.
Step 3. Add Streusel Topping Layer
Before you pop your cake into the oven, let’s add a crunchy, sweet streusel topping that’ll transform your simple blueberry crumble cake into a delightful treat. Creating this layer is quick and easy, but it makes all the difference.
Start by mixing cooled, melted butter with all-purpose flour in a medium bowl. You’ll want to use a pastry cutter or just your fingers to blend it together until it resembles coarse crumbs. This is essential, as the texture of your streusel depends on these crumbs being just the right size—not too big, but not powdery either.
Next, stir in brown sugar and a pinch of ground cinnamon. These ingredients provide the streusel with its signature sweetness and a light, warm spice that complements the blueberries perfectly. Confirm everything is well combined to avoid clumps of sugar or flour.
Once your streusel mix is ready, sprinkle it generously over the blueberry batter you’ve already spread in your baking pan. Guarantee an even distribution to cover the surface, as this will maximize the delightful crunch and flavor in every bite.
This step doesn’t just add a textural contrast; it elevates the entire dish, turning your cake squares into a multi-dimensional sensory experience.
Step 4. Bake at 350 Degrees
Once you’ve evenly spread the streusel over your blueberry batter, it’s time to bake. Preheat your oven to 350 degrees Fahrenheit, making sure it’s fully heated before you slide in your cake pan.
It’s essential to stick to this temperature to guarantee your blueberry crumble cake squares cook evenly and achieve that perfect balance of a crispy top layer with a soft, moist base.
Gently place your cake in the center of the oven. This position allows for an even distribution of heat, vital for a uniformly baked cake. Set your timer for 45-50 minutes, but remember, ovens can vary so it’s wise to check your cake at the 40-minute mark.
You’re looking for the streusel to turn a golden brown and for the edges to pull slightly away from the pan sides.
Don’t succumb to the temptation to open the oven too often as this can lead to heat loss and might affect the baking process. Just keep an eye on it through the oven window.
When the timer goes off, conduct a toothpick test: stick it in the center of the cake, and if it comes out clean, your blueberry crumble cake squares are done baking.
Step 5. Cool Before Cutting Squares
While your blueberry crumble cake squares cool down, resist the urge to cut into them immediately. It’s essential to allow your freshly baked masterpiece time to settle; this cooling period guarantees that the squares are easier to cut and firm enough to maintain their shape. The heat from the oven makes the squares soft and they can fall apart if cut too soon.
Here’s why patience pays off:
- Structural Integrity: The squares will hold together better when cooled, as the ingredients set into a stable structure.
- Enhanced Flavor: Cooling allows the flavors to meld together, creating a more cohesive and delicious taste experience.
- Safer Handling: Waiting avoids the risk of burning yourself with steamy hot blueberry filling.
Allow your cake to cool on a wire rack for about an hour or until it reaches room temperature. If you’re tempted to hasten the process, don’t rush it; the integrity of your squares could be compromised.
Once cooled, use a sharp knife or a pastry cutter for picture-perfect squares. This extra bit of patience guarantees each piece is as enjoyable as the last, making all your baking efforts worthwhile.

Cooking Tips
To guarantee your blueberry crumble cake squares bake evenly and boast a perfect texture, here’s an essential tip: always use room-temperature ingredients. This simple step guarantees that your butter blends more smoothly with sugar, yielding a creamier batter without unwanted clumps.
Additionally, eggs at room temperature will mix better and help your cake rise properly.
Another tip, don’t overmix your batter. You’ll want to fold the dry ingredients gently into the wet ones until just combined. Overmixing leads to developing the gluten in the flour too much, which can make your cake squares tough rather than tender. Just stir until you can’t see any more flour – no more, no less.
For the blueberries, consider tossing them lightly in flour before adding them to the batter. This nifty trick prevents them from sinking to the bottom during baking. They’ll be nicely distributed throughout each square, giving you a perfect bite every time.
Lastly, don’t skimp on the crumble topping. It provides a delightful texture contrast to the soft cake underneath. Keep your chunks of butter cold for the crumble, as this will help achieve that beautifully golden, crispy topping upon baking.
Final Thoughts
As you prepare to bake your blueberry crumble cake squares, keep in mind these essential tips to guarantee a delightful dessert:
- Preheat Your Oven: Achieving the correct temperature from the start is vital for proper baking.
- Measure Accurately: Use precise measurements for each ingredient to assure consistency and flavor balance in every bite.
- Fresh Is Best: Opt for fresh blueberries for a burst of natural sweetness and vibrant color.
Baking isn’t just about following a recipe; it’s about creating moments that you can share. Each square of your blueberry crumble cake will carry the signature of your effort and care, making it not just a treat, but a reflection of your culinary dedication.
As you mix, layer, and crumble, remember that your final product will reflect the quality of your ingredients and the precision of your methods. Don’t rush the process. Enjoy the aromas, the textures, and, ultimately, the flavors you’ve melded together.
Your dessert won’t only impress but also bring joy to those who taste it. So go ahead, give it your best shot, and watch the smiles spread with each delicious piece!
