Cinnamon Roll Swirl Coffee Cake From Scratch

Step 1

Preheat oven to 350 degrees. Lightly grease a 9x13 pan.

Step 2

In a large mixing bowl, cream together butter and sugar using a hand mixer until creamy. Then mix in eggs, sour cream, and vanilla extract until combined. Beat in 3 cups flour, baking powder, and salt until just combined. Pour into prepared pan.

Step 3

Make the topping in another mixing bowl by whisking together melted butter, brown sugar, 2 tablespoons flour, and cinnamon. Spoon in globs over the top of the cake batter. Then use a butter knife to swirl it into the batter.

Step 4

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

Step 5

Meanwhile, make the glaze by whisking together powdered sugar, milk, and vanilla in another bowl. Drizzle over the cake while it is still warm.
