Step-by-Step Guide
1. Prep Your Oven and Pan
Preheat your oven to 350 degrees Fahrenheit. Grease your 9-inch square pan with butter. You can also use parchment paper for easy lifting.
2. Make the Streusel Topping
Mix flour, brown sugar, cinnamon, and salt. Add the cold, cubed butter to the bowl. Use your fingers to rub the butter in. The mixture should look like coarse crumbs. Put this in the fridge until needed.
3. Mix Dry Ingredients
In a medium bowl, whisk the flour together. Add the baking powder and the salt. Set this bowl aside for a moment.
4. Cream Butter and Sugar
In a large bowl, beat the softened butter. Add the granulated sugar slowly. Beat until the mixture is light and fluffy. This usually takes about three minutes.

6. Combine Wet and Dry
Add half of the dry flour mixture. Pour in the milk and mix slowly. Add the rest of the flour mixture. Do not overmix the batter.
7. Fold in Blueberries
Use a spatula to fold in the berries. Be very gentle so they do not burst. This keeps the cake pretty and white.
8. Assemble and Bake
Spread the batter into your prepared pan. Sprinkle the cold streusel topping over the top. Bake for 40 to 45 minutes.
