Blueberry Coffee Cake

Ingredients:

For the Streusel Topping:

• 1/2 cup granulated sugar
• 1/3 cup all-purpose flour
• 1/2 teaspoon ground cinnamon
• 4 tablespoons unsalted butter, cold and cut into small pieces

For the Blueberry Cake:

• 2 cups all-purpose flour
• 2 teaspoons baking powder
• 1/2 teaspoon baking soda
• 1/2 teaspoon salt
• 1/2 cup unsalted butter, softened
• 1 cup granulated sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 1 cup sour cream
• 1 1/2 cups fresh or frozen blueberries (if using frozen, do not thaw)

Instructions:

For the Streusel Topping:

1. In a small bowl, combine the granulated sugar, flour, and ground cinnamon.
2. Add the cold butter pieces and use a pastry cutter or your fingers to mix until the mixture resembles coarse crumbs. Set the streusel topping aside.

For the Cake:

1. Preheat your oven to 350°F (175°C). Grease and flour a 9×9-inch square baking pan or a similar-sized baking dish.
2. In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
3. In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy, which takes about 2-3 minutes.
4. Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next one. Stir in the vanilla extract.
5. Gradually add the dry mixture to the wet mixture, alternating with the sour cream, beginning and ending with the dry mixture. Mix until just combined; do not overmix.
6. Gently fold in the blueberries, being careful not to crush them.
7. Spread half of the cake batter into the prepared baking pan.
8. Sprinkle half of the streusel topping evenly over the batter.
9. Add the remaining cake batter on top, spreading it evenly.
10. Finish by sprinkling the remaining streusel topping over the second layer of batter.
11. Bake in the preheated oven for 45-50 minutes or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
12. Allow the blueberry coffee cake to cool in the pan for about 15-20 minutes before slicing and serving.
13. Enjoy a slice of this delicious blueberry coffee cake with your morning coffee or tea.
