Instructions

Preheat the oven to 350℉ (175 ℃). Grease a 9×9-inch pan and line with parchment paper.
In a medium bowl, toss 2 1/4 cups (382 g) of blueberries with 1 tbsp (8 g) of flour; set aside. Reserve the remaining blueberries for topping.
In a large bowl, cream the softened butter, granulated sugar, and brown sugar with an electric mixer.
Add flour and salt, mixing on low speed until crumbly.
Remove 3/4 cup (125 g) of the mixture to a small bowl. To this, add the remaining butter, brown sugar, and cinnamon; mix until clumpy and set aside for streusel.
Dissolve baking soda in buttermilk and add to the larger bowl along with the egg and vanilla; mix until combined.
Gently fold in the larger portion of blueberries with a rubber spatula into the batter.
Spread the batter into the prepared pan evenly.
Top with remaining blueberries and streusel mixture.
Bake for 70-80 minutes until a toothpick comes out clean.
Cool in the pan on a wire rack for 30 minutes; pull up on parchment to release the cake and cool completely.
Mix powdered sugar with milk in a small bowl until pourable; drizzle over cooled cake and slice into 16 pieces.

Notes

Make sure to let the cake cool completely before icing to prevent the glaze from melting off.
Store any leftovers in an airtight container at room temperature for up to 3 days.
For added flavor, consider adding lemon zest to the batter.
