For the Cake
- 2 cups all-purpose flour (about 9 ounces, measured carefully)
- ½ cup granulated sugar
- 2 teaspoons baking powder

How to Make It
Preheat and Prepare
Start by preheating your oven to 350°F. Lightly grease or spray a 9-inch square baking pan. This step sets the tone for a stress-free bake and ensures your cake releases easily, making it great for make-ahead breakfasts or casual family dinners.
Mix the Dry
Ingredients
In a large bowl, whisk together the flour, sugar, and baking powder. Cutting the butter into small pieces before adding helps it blend evenly into the thick batter, creating that tender, comforting texture this cake is known for.
Build the Batter
Add the egg, milk, softened butter, and lemon peel to the bowl. Mix just until the dry ingredients are moistened. The batter will be very thick this is exactly what you want. Don’t rush this step; gently working the batter ensures a soft, satisfying crumb that feels hearty and filling without being dense.
Fold in the Blueberries
Carefully fold in the blueberries. Because the batter is thick, this takes a bit of patience, but it’s worth it. Each fold brings bursts of juicy fruit throughout the cake, making every slice feel balanced and nourishing.
Spread the batter evenly into the prepared pan, smoothing the top as best you can.
Prepare the Topping
In a small bowl or mini food processor, combine the sugar, flour, walnuts, and cinnamon. Add the cold butter and pulse or cut it in by hand until the mixture becomes crumbly. Using your fingers works beautifully here and keeps the process cozy and hands-on.
Sprinkle the topping evenly over the batter, creating that signature coffee cake finish that bakes into a golden, comforting layer.
Bake to Perfection
Bake at 350°F for 40–45 minutes, or until a toothpick inserted into the center comes out clean. The top should be lightly golden and fragrant, filling your kitchen with that unmistakable homemade warmth.
Optional Drizzle
If using the drizzle, whisk together the powdered sugar and milk until smooth. Adjust the consistency as needed, then gently drizzle over the cooled cake. Let it sit until the sugar sets for a bakery-style finish that feels just a little indulgent.
