• ¾ cup granulated sugar
• 2 large eggs
• 1 tsp vanilla extract
• 1 cup sour cream (or plain yogurt)
• 1½ cups blueberries (fresh or frozen, tossed in 1 tbsp flour)

For the Streusel Topping:

• ½ cup brown sugar, packed
• ½ cup all-purpose flour
• ¼ cup unsalted butter, cold and cubed
• 1 tsp ground cinnamon

Instructions

1. Prepare the Pan
   Preheat oven to 350°F (175°C). Grease and flour an 8-inch square baking pan or line with parchment paper.
2. Make the Streusel
   In a small bowl, combine brown sugar, flour, butter, and cinnamon. Use a fork or pastry cutter to blend until crumbly. Set aside.
3. Mix the Batter
   In a medium bowl, whisk together flour, baking powder, baking soda, and salt. In a large bowl, cream butter and sugar until light and fluffy. Beat in eggs and vanilla. Alternate adding the dry ingredients and sour cream, mixing just until combined.
4. Add Blueberries
   Gently fold in blueberries coated with flour.
5. Assemble and Bake
   Spread the batter into the prepared pan. Sprinkle streusel evenly over the top. Bake for 40–45 minutes, or until a toothpick inserted in the center comes out clean.
6. Cool and Serve
   Let cake cool for 15 minutes before slicing. Serve warm or at room temperature.
