Best & Easiest Cinnamon Coffee Cake

Ingredients

• 1 1/2 cups all-purpose flour
• 1 1/2 teaspoons double-acting baking powder
• 1 cup sour cream
• 1 teaspoon baking soda
• 1/2 cup unsalted butter, softened
• 1-1 1/3 cup granulated sugar
• 2 large eggs
• 1 teaspoon vanilla
• 1/3 cup firmly packed light brown sugar
• 1 teaspoon cinnamon

Directions

1. 1

   In a bowl whisk together the flour, the baking powder, and a pinch of salt and in another bowl stir together the sour cream and the baking soda.

2. 2

   In a large bowl cream together the butter and 1 cup of the granulated sugar until the mixture is light and fluffy. Make sure you cream it well or the batter will be very thick. Add the eggs, 1 at a time, beating well after each addition, and beat in the vanilla.

3. 3

   Stir in the flour mixture alternately with the sour cream mixture and stir the batter until it is combined well.

4. 4

   Pour the batter into a buttered 10-inch round cake pan. In a small bowl stir together the remaining 1/3 cup granulated sugar, the brown sugar, and the cinnamon and swirl the sugar mixture into the batter. (If you have a very thick batter, layer it like an oreo cookie instead batter, cinnamon sugar in the middle, and batter on top.).

5. 5

   Bake the cake in the middle of a preheated 350°F oven for 45 to 50 minutes, or until a tester comes out clean. Transfer it to a rack, and let it cool.
