  • 3/4 cup vegetable oil Can substitute with canola oil.
  • 1 can cooking spray For greasing the baking dish.
For the Cinnamon Filling
  • 1 cup light brown sugar, packed Can be substituted with dark brown sugar for a deeper flavor.
  • 2 tsp ground cinnamon Ensure it is well-mixed with the sugar.
For the Glaze

Method
 

Preparation
  1. Preheat the oven to 350°F and spray a 9 x 13-inch baking dish with cooking spray.
  2. In a large bowl, beat together the cake mix, eggs, sour cream, and vegetable oil until smooth, about 2 minutes.
  3. In a small bowl, mix the light brown sugar and cinnamon to create the filling.
Layering
  1. Spread half of the batter into the prepared baking dish.
  2. Sprinkle the cinnamon-sugar mixture evenly over the batter.
  3. Top with the remaining batter and carefully spread it to cover the filling.
  4. Swirl the batter with a knife to create a marbled effect.
Baking and Glazing
  1. Bake for 40 to 45 minutes, or until a toothpick inserted in the center comes out clean.
  2. In a bowl, whisk the powdered sugar, 4 tablespoons of milk, vanilla extract, and optional honey until thick but pourable. Adjust with more milk if too thick.
  3. Immediately pour the glaze over the hot cake and let it soak in before serving.
Serving
  1. Allow the cake to cool for at least 30 minutes before slicing into 12 squares.
  2. Serve warm or at room temperature.
