Ingredients - Cake
- 12 Tbsp unsalted butter
- 1 tsp salt
- 1.5 cups granulated sugar
- 0.33 cup light brown sugar
2.5 tsp baking powder
2 tsp vanilla
3 large eggs
0.75 cup sour cream or plain yogurt
1.25 cups milk- 3.75 cup all-purpose flour
Cookware
- 1 9" x 13" pan or two 9" round cake pans
- 1 large bowl
- 1 table knife
Instructions
Step 1
Preheat the oven to 350°F.
Step 2
Lightly grease a 9" x 13" pan or two 9" round cake pans.
Step 3
Make the topping by whisking together the granulated sugar, salt, all-purpose flour, and cinnamon. Add the melted butter, stirring until well combined. Set the topping aside.
Step 4
Make the filling by mixing together the dark brown sugar, cinnamon, and unsweetened cocoa powder. Note that the cocoa powder is used strictly for color, not flavor; leave it out if you like. Set it aside.
Step 5
To make the cake, in a large bowl, beat together the unsalted butter, salt, granulated sugar, light brown sugar baking powder, and vanilla until well combined and smooth.
Step 6
Add the eggs one at a time, beating well after each addition.
Step 7
In a separate bowl, whisk together the sour cream or plain yogurt and milk till well combined. You don't need to whisk out all the lumps.
Step 8
Add the all-purpose flour to the butter mixture alternately with the milk/sour cream mixture, beating gently to combine.
Step 9
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.
Step 10
Sprinkle the filling evenly on the batter.
Step 11
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.
Step 12
Sprinkle the topping over the batter in the pan.
Step 13
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.
Step 14
Remove the cake from the oven and allow it to cool for 20 minutes before cutting and serving. Serve cake right from the pan.
