Ingredients
Scale
- 1 stick (1/2 cup) butter, at room temperature
- 1–1/2 cups (300 grams) granulated sugar
- 3 large eggs, separated
- 1–1/2 teaspoons vanilla extract
- 2 cups (16 ounces) sour cream
- 3–1/4 cups (390 grams) all-purpose flour
- 1 teaspoon baking powder
- 1–1/2 teaspoons baking soda
- Pinch of kosher salt
- 12 ounces semisweet or bittersweet chocolate chips
- 1/2 cup (100 grams) granulated sugar
- 1 teaspoon ground cinnamon
Instructions
- Preheat the oven to 350°. Lightly grease a 9 x 13-inch baking pan and form a sling with parchment paper with enough overhang to form handles to lift the cake out of the pan.
- In the bowl of the stand mixer fitted with the whisk attachment, beat the egg whites until glossy and stiff peaks form. Transfer to a mixing bowl.
- In the same bowl of a stand mixer fitted with a paddle attachment, cream the butter and 1-1/2 cups granulated sugar until light and fluffy, about 5 minutes. Beat in the egg yolks and vanilla extract.
- In a medium mixing bowl, combine the flour, baking powder and salt together and stir to mix. Mix the flour mixture alternately with the sour cream into the butter mixture until all of the ingredients are combined. Fold the whipped egg whites gently into the batter.
- Pour half of the batter into the prepared baking pan and spread evenly to the edges. Sprinkle half of the chocolate chips over the top. Pour the remaining batter over top and gently spread again to the edges.
- Combine the granulated sugar and ground cinnamon in a small bowl. Sprinkle over the top of the cake batter and then sprinkle the remaining chocolate chips on top. Bake for 40 to 50 minutes, rotating the pan halfway through the baking time, until a tester inserted in the center comes out clean. Let the cake cool in the pan. Remove from the pan using the parchment handles and cut into 12 large squares.
