→ Cake

10 - ½ cup unsalted butter, softened (1 stick)
11 - 1 cup granulated sugar
12 - 2 large eggs
13 - 1 cup sour cream (full-fat or reduced-fat)
14 - ½ teaspoon vanilla extract
15 - 1½ cups all-purpose flour
16 - ½ teaspoon baking powder
17 - ¼ teaspoon baking soda
18 - ¼ teaspoon iodized salt

# Steps:

01 - Preheat your oven to 350℉/175℃. Grease an 8-inch cake pan generously with butter.
02 - In a small bowl, whisk together 2 tablespoons light brown sugar, 1 tablespoon all-purpose flour, and 1 teaspoon cinnamon. Set aside.
03 - In a medium bowl, combine ½ cup light brown sugar, ¾ cup all-purpose flour, 1 teaspoon cinnamon, ⅛ teaspoon salt, and ½ cup chopped pecans or walnuts if using. Add ½ cup cold unsalted butter (cubed) and mix with your fingers until crumbs form and butter is evenly distributed. Set aside.
04 - In a large bowl or stand mixer, cream together ½ cup unsalted butter with 1 cup granulated sugar on medium-high speed until pale and fluffy, about 3-5 minutes. Add 2 large eggs and mix until incorporated. Add 1 cup sour cream and ½ teaspoon vanilla extract, mixing until well combined.
05 - In a separate bowl, whisk or sift 1½ cups all-purpose flour with ½ teaspoon baking powder, ¼ teaspoon baking soda, and ¼ teaspoon iodized salt.
06 - Add the dry ingredients to the creamed butter mixture and fold gently with a spatula or wooden spoon until just combined.
07 - Spoon half of the batter into the prepared pan and smooth into an even layer. Sprinkle the cinnamon filling evenly over the batter.
08 - Spoon the remaining batter in dollops evenly over the filling and smooth into an even layer. Sprinkle the streusel mixture evenly over the top of the batter.
09 - Bake the coffee cake in the preheated oven for 35-45 minutes or until a toothpick inserted in the center comes out clean or with a few crumbs. Check after 25 minutes; if the streusel is browning too much, lightly tent with foil and continue baking.
10 - Remove the cake from the oven and let cool for at least 10 minutes before serving.

# Tips:

01 - Ensure to use full-fat or reduced-fat sour cream, not fat-free. You may substitute plain yogurt, but avoid Greek-style yogurt.
02 - Once cooled, store the cake in an airtight container for up to 3 days or freeze wrapped in plastic wrap, foil, and a freezer-safe bag.
