Step 1: Crumble Preparation
- In a medium bowl, combine flour, dark brown sugar, granulated sugar, and cinnamon. Cut in the butter until the mixture resembles coarse crumbs. Set aside.
Step 2: Preheat and Prepare the Pan
- Preheat your oven to 175ºC (350ºF) and grease a 9-inch springform pan.
Step 3: Creaming Butter and Sugar
- In a large mixing bowl, beat the softened butter and granulated sugar until light and fluffy, about 3-4 minutes.
Step 4: Incorporating Eggs
- Add the eggs to the creamed mixture, one at a time, mixing thoroughly on low speed before adding the next.
Step 5: Adding Dry Ingredients and Flavorings
- Gently mix half of the flour, baking powder, and salt into the batter, followed by lemon zest, sour cream, vegetable oil, and vanilla extract. Gradually add remaining dry ingredients.
Step 6: Preparing Blueberries and Folding
- Toss the blueberries with cornstarch to coat them, then fold half into the batter and pour into the prepared pan.
Step 7: Topping and Baking
- Sprinkle remaining blueberries and crumble topping over the batter and bake for 45-50 minutes.
Step 8: Cooling and Glazing
