Classic Coffee Cake

Ingredients

• 2 cup all-purpose flour
• 1 cup granulated sugar
• 0.5 cup unsalted butter, softened
• 2 whole eggs
• 1 cup sour cream
• 1 tsp vanilla extract
• 1 tsp baking powder
• 0.5 tsp baking soda
• 0.25 tsp salt
• 0.75 cup brown sugar (for streusel)
• 0.5 cup all-purpose flour (for streusel)
• 1.5 tsp ground cinnamon (for streusel)
• 0.25 cup unsalted butter, cold and cubed (for streusel)

Instructions

1. 1

   Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking pan.

2. 2

   Make the streusel: In a medium bowl, combine brown sugar, ½ cup flour, and cinnamon. Cut in the cold butter with a pastry cutter or your fingers until the mixture resembles coarse crumbs. Set aside.

3. 3

   In a large bowl, beat the softened butter and granulated sugar together until light and fluffy, about 3 minutes.

4. 4

   Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.

5. 5

   In a separate bowl, whisk together the 2 cups of flour, baking powder, baking soda, and salt.

6. 6

   Add the dry ingredients to the butter mixture in three additions, alternating with the sour cream, beginning and ending with the flour mixture. Mix until just combined — do not overmix.

7. 7

   Spread the batter evenly into the prepared pan. Sprinkle the streusel topping evenly over the batter.

8. 8

   Bake for 40–45 minutes, or until a toothpick inserted in the center comes out clean.

9. 9

   Let cool in the pan for at least 15 minutes before slicing and serving.
