Ingredients

The following ingredients have 4 Servings
  • 2 1/2 cups flour
  • 2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon kosher salt
  • 1 cup unsalted butter (softened)
  • 1 cup sugar
  • 1/2 cup brown sugar
  • 3 eggs
  • 1 1/2 cups sour cream
  • 1 teaspoon vanilla
  • 3 tablespoons sugar
  • 1 1/2 teaspoons cinnamon
  • 11.5 ounces milk chocolate chips

Instruction

  • Begin by preheating the oven to 350 degrees F. Spray a 9x13-inch baking dish with baking spray. Set aside.
  • In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
  • In a large bowl, cream together the butter, sugar, and brown sugar, with an electric mixer until smooth. (This will take about three minutes.) Add the eggs, one at a time, beating well after each addition. Add the sour cream and vanilla. Beat to combine.
  • Add the prepared dry ingredients to the wet ingredients. Beat to combine. (Usually, this takes about 2 minutes at medium speed.)
  • Pour half of the batter into the prepared baking dish. Spread in an even layer with a spatula.
  • In a small bowl, prepare the topping by whisking together the sugar and cinnamon. Sprinkle half of this mixture on the batter. Top with half of the chocolate chips.
  • Add the remaining batter and spread it into an even layer with a spatula. Sprinkle the batter with the remaining cinnamon-sugar mixture and chocolate chips.
  • Bake for 35-40 minutes or until a toothpick inserted near the center comes out clean. Do not overbake.
  • Allow the cake to cool before serving. Cut into 12 pieces for larger servings or 18 pieces for smaller treats.
