Cinnamon Swirl Coffee Cake is a delicious treat for breakfast or a brunch. The cinnamon flavor pairs great with a warm cup of coffee.
- •For the streusel topping
- 1 1/4 cups granulated sugar
- 1/4 teaspoon salt (if you use unsalted butter)
- 1 1/2 cups King Arthur Unbleached All-Purpose Flour
- 1 tablespoon ground cinnamon
- 6 tablespoons butter, melted
- •For the filling
- 1 cup brown sugar, light or dark
- 1 1/2 tablespoons ground cinnamon
- 1 teaspoon unsweetened cocoa powder
- •For the cake
- 3/4 cup butter
- 1 teaspoon salt (1 1/4 teaspoons if you use unsalted butter)
- 1 1/2 cups granulated sugar
- 1/3 cup brown sugar
- 2 1/2 teaspoons baking powder
- 2 teaspoons vanilla extract
- 3 large eggs
- 3/4 cup sour cream or plain yogurt
- 1 1/4 cups milk (anything from skim to whole)
- 3 3/4 cups Unbleached All-Purpose Flour
- Preheat the oven to 350°F. Lightly grease a 9″ x 13″ pan, or two 9″ round cake pans.
- Make the topping by whisking together the sugar, salt, flour, and cinnamon. Add the melted butter, stirring till well combined. Set the topping aside.
- Make the filling by mixing together the brown sugar, cinnamon, and cocoa powder. Note that the cocoa powder is used strictly for color, not flavor; leave it out if you like. Set it aside.
- To make the cake: In a large bowl, beat together the butter, salt, sugars, baking powder, and vanilla until well combined and smooth.
- Add the eggs one at a time, beating well after each addition.
- In a separate bowl, whisk together the sour cream or yogurt and milk till well combined. You don’t need to whisk out all the lumps.
- Add the flour to the butter mixture alternately with the milk/sour cream mixture, beating gently to combine.
- Pour/spread half the batter (a scant 3 cups) into the prepared pan(s), spreading all the way to the edges. If you’re using two 9″ round pans, spread 1 1/3 cups batter in each pan.
- Sprinkle the filling evenly atop the batter.
- Spread the remaining batter atop the filling. Use a table knife to gently swirl the filling into the batter, as though you were making a marble cake. Don’t combine filling and batter thoroughly; just swirl the filling through the batter.
- Sprinkle the topping over the batter in the pan.
- Bake the cake until it’s a dark golden brown around the edges; medium-golden with no light patches showing on top, and a toothpick or cake tester inserted into the center comes out clean, about 55 to 60 minutes for the 9″ x 13″ pan, 50 to 55 minutes for the 9″ round pans. When pressed gently in the middle, the cake should spring back.
- Remove the cake from the oven and allow it to cool for 20 minutes before cutting and serving. Serve cake right from the pan
