In a small bowl, mix together the brown sugar, 1/2 cup of gluten-free all-purpose flour, and cinnamon. Cut in 1/4 cup of cold unsalted butter until the mixture resembles coarse crumbs. Set aside.
In a large bowl, whisk together the remaining 1 1/2 cups of gluten-free all-purpose flour, baking powder, and salt.
In another large bowl, beat the remaining 1/4 cup of unsalted butter and sugar until light and fluffy. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
Gradually add the dry ingredients to the butter mixture, alternating with the milk. Mix until just combined. Gently fold in the blueberries.
Preheat the oven to 350°F (175°C). Grease a 9-inch square baking pan. Pour the batter into the prepared pan and sprinkle the streusel topping evenly over the batter. Bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean.
Let the coffee cake cool in the pan for 10 minutes before slicing and serving.
