👩🍳 Instructions
1. Prepare Your Pan
Preheat oven to 350°F (175°C). Grease a 9×9 inch baking pan or a bundt pan.
2. Make the Streusel
In a bowl, combine brown sugar, cinnamon, and flour. Cut in the cold butter until crumbly. Set aside.
3. Mix the Cake Batter
In a large bowl: Cream butter + sugar until fluffy. Add eggs one at a time. Mix in sour cream + vanilla.
4. Combine Dry Ingredients
In a separate bowl, whisk together: flour, baking soda, baking powder, salt.
Add dry ingredients to wet ingredients and mix gently until just combined.
5. Add the Blueberries
Toss blueberries lightly in 1 Tbsp flour (prevents sinking). Fold gently into batter.
6. Layer the Cake
Pour half the batter into the prepared pan. Sprinkle half the streusel. Add remaining batter. Top with remaining streusel.
7. Bake
Bake 40–50 minutes, or until a toothpick comes out clean. Cool in the pan 15 minutes before slicing.
8. Optional Glaze
Drizzle glaze over cooled cake.
