Blueberry Crumbly Delight

1. Preheat Oven and Prepare Pan

Preheat your oven to 350°F, positioning the rack in the lower-middle section. While the oven warms up, grease a 9-inch round cake pan and line the bottom with parchment paper.

2. Prepare Streusel

In a stand mixer fitted with the paddle attachment, combine ½ cup of all-purpose flour, ½ cup of light brown sugar, 2 tablespoons of granulated sugar, ¼ teaspoon of ground cinnamon, and a pinch of salt. Beat these ingredients on medium speed for about 45 seconds to mix them well. Then, add the 4 tablespoons of softened butter. Continue to beat the mixture until it resembles wet sand, which should take about 2½ minutes.

3. Prepare Dry Ingredients for Cake

In a medium bowl, whisk together 1½ cups of all-purpose flour and 1½ teaspoons of baking powder.

4. Cream Butter and Sugar

In your stand mixer, still with the paddle attachment, beat 10 tablespoons of softened butter, ⅔ cup of granulated sugar, ½ teaspoon of salt, and ½ teaspoon of grated lemon zest on medium speed. After about 3 minutes, the mixture should be light and fluffy.

5. Add Vanilla and Eggs

Add 1½ teaspoons of vanilla extract and continue to beat for another 30 seconds. Add the eggs one at a time, making sure each egg is fully incorporated before adding the next.

6. Combine Dry Ingredients and Batter

Gradually add the flour mixture to the batter, beating on low speed for about 20 seconds, until just combined. It's important not to overmix the batter to keep the cake tender.

7. Fold in Blueberries

Gently fold in the 4 cups of blueberries using a rubber spatula. Be careful to distribute the blueberries evenly without crushing them.

8. Transfer Batter to Pan

Transfer the batter to your prepared cake pan, spreading it out evenly. Sprinkle the streusel topping over the batter, covering it completely.

9. Bake the Cake

Place the pan in the preheated oven and bake for 45 to 55 minutes. You'll know the cake is done when a toothpick inserted into the center comes out clean or with just a few moist crumbs.

10. Cool and Serve

Once baked, let the cake cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely. For a delightful finishing touch, serve your Blueberry Crumbly Delight with a scoop of vanilla ice cream. Enjoy!
