Ingredients:

For the Blueberry Filling:

6 cups fresh blueberries, rinsed and sorted
¾ cup granulated sugar
¼ cup cornstarch
¼ cup water
1 tablespoon lemon juice
1 teaspoon lemon zest
Pinch of salt

For the Crumble Topping:

1 cup all-purpose flour
½ cup packed light brown sugar
½ cup rolled oats (not instant)
½ teaspoon ground cinnamon
¼ teaspoon ground nutmeg
½ cup (1 stick) cold unsalted butter, cut into small cubes
¼ cup chopped pecans or walnuts (optional)

For the Cake Base:

1 ½ cups all-purpose flour
1 ½ teaspoons baking powder
½ teaspoon baking soda
½ teaspoon salt
¾ cup granulated sugar
½ cup (1 stick) unsalted butter, softened
2 large eggs
1 teaspoon vanilla extract
½ cup sour cream or plain Greek yogurt

Preparing the Blueberry Filling:

Okay, let’s start with the heart of our Blueberry Fiesta the luscious blueberry filling! This is where the magic happens, and trust me, it’s super easy.

Combine the Blueberries and Sugar: In a large saucepan, gently combine the fresh blueberries and granulated sugar. Give them a good toss so the sugar coats all those juicy berries. This helps to draw out some of their natural juices, which will create a beautiful sauce.
Prepare the Cornstarch Slurry: In a small bowl, whisk together the cornstarch and water until smooth. This is our thickening agent, ensuring the filling isn’t too runny. Make sure there are no lumps!
Cook the Filling: Place the saucepan with the blueberries and sugar over medium heat. Cook, stirring occasionally, until the blueberries start to release their juices and the mixture begins to simmer. This usually takes about 5-7 minutes.
Thicken the Filling: Pour the cornstarch slurry into the saucepan and stir constantly. Continue cooking for another 2-3 minutes, or until the filling has thickened slightly and is glossy. It should coat the back of a spoon.
Add Flavor Boosters: Remove the saucepan from the heat and stir in the lemon juice, lemon zest, and a pinch of salt. The lemon juice brightens the flavor of the blueberries, while the zest adds a lovely aromatic note. The salt enhances the sweetness.
Let it Cool: Set the blueberry filling aside to cool slightly while you prepare the crumble topping and cake base. This prevents the filling from melting the butter in the crumble topping.

Making the Crumble Topping:

Now, for the irresistible crumble topping! This adds a delightful textural contrast to the soft cake and juicy filling. Plus, who doesn’t love a good crumble?

Combine Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, brown sugar, rolled oats, cinnamon, and nutmeg. The cinnamon and nutmeg add warmth and spice to the crumble.
Cut in the Butter: Add the cold, cubed butter to the bowl. Using a pastry blender or your fingertips, cut the butter into the dry ingredients until the mixture resembles coarse crumbs. The key here is to work quickly so the butter doesn’t melt. You want small pieces of butter throughout the mixture, which will create those lovely crumbles.
Add Nuts (Optional): If you’re using nuts, stir in the chopped pecans or walnuts. They add a nice crunch and nutty flavor.
Chill (Optional but Recommended): For the best results, cover the bowl and chill the crumble topping in the refrigerator for at least 30 minutes. This helps the butter stay cold and prevents the crumble from spreading too much during baking.

Preparing the Cake Base:

Time to create the foundation for our Blueberry Fiesta the cake base! This provides a soft and tender layer that perfectly complements the filling and crumble.

Preheat and Prepare Pan: Preheat your oven to 375°F (190°C). Grease and flour a 9×13 inch baking pan. You can also line the pan with parchment paper, leaving an overhang on the sides for easy removal.
Combine Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. The baking powder and baking soda help the cake rise, while the salt enhances the flavors.
Cream Butter and Sugar: In a large bowl, cream together the softened butter and granulated sugar until light and fluffy. This usually takes about 3-5 minutes with an electric mixer. Creaming the butter and sugar incorporates air into the mixture, which contributes to a tender cake.
Add Eggs and Vanilla: Beat in the eggs one at a time, then stir in the vanilla extract. Make sure each egg is fully incorporated before adding the next. The vanilla extract adds a lovely aroma and flavor.
Alternate Dry and Wet Ingredients: Gradually add the dry ingredients to the wet ingredients, alternating with the sour cream or Greek yogurt, beginning and ending with the dry ingredients. Mix until just combined. Be careful not to overmix, as this can result in a tough cake. Overmixing develops the gluten in the flour, which can make the cake dense.
- Add about one-third of the dry ingredients and mix until just combined.
- Add half of the sour cream or Greek yogurt and mix until just combined.
- Add another one-third of the dry ingredients and mix until just combined.
- Add the remaining sour cream or Greek yogurt and mix until just combined.
- Add the remaining dry ingredients and mix until just combined.

Assembling and Baking the Blueberry Fiesta:

The grand finale! Now we bring all the components together and bake our masterpiece.

Spread the Cake Batter: Pour the cake batter into the prepared baking pan and spread it evenly.
Top with Blueberry Filling: Spoon the blueberry filling over the cake batter, spreading it evenly. Don’t worry if it doesn’t completely cover the batter; it will spread during baking.
Sprinkle with Crumble Topping: Sprinkle the crumble topping evenly over the blueberry filling. Make sure to cover the entire surface for maximum crumble goodness.
Bake: Bake in the preheated oven for 45-55 minutes, or until the crumble topping is golden brown and a toothpick inserted into the center of the cake comes out clean or with a few moist crumbs. The baking time may vary depending on your oven, so keep an eye on it.
Cool: Let the Blueberry Fiesta cool in the pan for at least 30 minutes before serving. This allows the filling to set slightly and makes it easier to cut.
Serve: Serve warm or at room temperature. You can enjoy it as is, or top it with a scoop of vanilla ice cream or a dollop of whipped cream for an extra special treat.

Tips for Success:

Use Fresh Blueberries: While frozen blueberries can be used in a pinch, fresh blueberries will give you the best flavor and texture.
Don’t Overmix the Cake Batter: Overmixing can result in a tough cake. Mix until just combined.
Chill the Crumble Topping: Chilling the crumble topping helps the butter stay cold and prevents it from spreading too much during baking.
Adjust Sweetness to Taste: If you prefer a less sweet dessert, you can reduce the amount of sugar in the blueberry filling or crumble topping.
Add a Glaze (Optional): For an extra touch of sweetness, you can drizzle a simple glaze over the cooled Blueberry Fiesta. To make a glaze, whisk together 1 cup of powdered sugar with 2-3 tablespoons of milk or lemon juice until smooth.

Variations:

Other Berries: Feel free to substitute other berries for the blueberries, such as raspberries, blackberries, or strawberries.
Different Nuts: Try using different nuts in the crumble topping, such as almonds, walnuts, or macadamia nuts.
Spice it Up: Add a pinch of ground ginger or cardamom to the crumble topping for a warm and spicy flavor.
Citrus Zest: Experiment with different citrus zests, such as orange or lime, in the blueberry filling.
