Essential Ingredients
Here’s what you’ll need to make this delicious dish:
All-Purpose Flour: Essential for structure; choose unbleached for best results.
Sugar: Granulated sugar sweetens the batter perfectly; brown sugar adds moisture and depth.
Baking Powder: Ensures your cake rises beautifully; check expiration dates for effectiveness.
Salt: A pinch enhances all flavors; don’t skip this crucial step.
Unsalted Butter: Use room temperature butter to create a rich texture without excess salt.
Eggs: These bind the ingredients; use large eggs for consistency.
Milk: Whole milk adds moisture; you can use buttermilk for extra tanginess.
Fresh Blueberries: Look for plump, juicy berries—frozen works too but may add moisture.
Cinnamon: A sprinkle lends warmth and complements the blueberries beautifully.
Oats (for topping): Adds crunch and nuttiness; opt for rolled oats rather than instant.
Brown Sugar (for topping): This gives your crumb topping that caramelized flavor we all crave!

How to Make blueberry crumb cake
Preheat Your Oven: Begin by preheating your oven to 350°F (175°C). Grease a 9-inch square baking pan with butter or cooking spray to prevent sticking.
Prepare the Crumb Topping: In a mixing bowl, combine flour, oats, brown sugar, cinnamon, and melted butter until it resembles coarse crumbs. Set aside while you prepare the batter.
Create the Cake Batter: In another bowl, whisk together flour, sugar, baking powder, and salt until well blended. In another bowl, mix softened butter with eggs and milk until creamy.
Combine Dry and Wet Ingredients: Gradually add the dry ingredients to the wet mixture while stirring gently. Be careful not to overmix; you want it light and fluffy!
Add Blueberries: Gently fold in fresh blueberries using a spatula so they don’t burst—this preserves their lovely shape and juice.
Bake Your Cake: Pour the batter into your prepared pan and sprinkle the crumb topping evenly over it. Bake for 45-50 minutes until golden brown and a toothpick comes out clean from the center.
Enjoy this delightful blueberry crumb cake warm or at room temperature—it’s delicious both ways!
