Ingredients

• 2.5 cups all-purpose flour
• 2 teaspoons baking powder
• 0.5 teaspoons baking soda
• 0.25 teaspoons salt
• 0.5 cups unsalted butter, softened
• 1 cup granulated sugar
• 2 large eggs
• 2 teaspoons vanilla extract
• 1 cup sour cream
• 0.5 cups brown sugar
• 2 teaspoons cinnamon
• 0.25 cups unsalted butter, melted (for streusel)
• 2 cups powdered sugar
• 0.5 cups unsalted butter, softened (for buttercream)
• 2 tablespoons heavy cream
• 1 teaspoons vanilla extract (for buttercream)

Directions

Step 1

Preheat your oven to 350°F (175°C). Grease a 9-inch springform pan or cake pan and line the bottom with parchment paper.

Step 2

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.

Step 3

In a large bowl, cream together the softened butter and granulated sugar until light and fluffy, about 3 minutes using a hand mixer or stand mixer.

Step 4

Beat in the eggs one at a time, followed by the vanilla extract.

Step 5

Add the dry ingredients to the wet ingredients in 3 parts, alternating with the sour cream, starting and ending with the dry ingredients. Mix until just combined. Do not overmix.

Step 6

In a small bowl, combine the brown sugar and cinnamon to make the streusel topping. Stir in the melted butter until crumbly.

Step 7

Pour half of the cake batter into the prepared pan and spread it evenly. Sprinkle half of the streusel topping over the batter. Add the remaining batter and smooth the top, then sprinkle the rest of the streusel evenly over the top layer.

Step 8

Bake in the preheated oven for 35–40 minutes, or until a toothpick inserted into the center comes out clean.

Step 9

While the cake cools, prepare the buttercream by beating the softened butter and powdered sugar together until smooth. Add the heavy cream and vanilla extract, and beat until creamy and spreadable.

Step 10

Allow the cake to cool completely before removing it from the pan. Once cool, spread the buttercream frosting evenly over the top of the cake.

Step 11

Slice and serve. Store leftovers in an airtight container at room temperature for up to 2 days.
