- 1 3/4 cups white sugar
- 1/2 cup unsalted butter, softened
- 4 eggs, beaten
- 1 teaspoon vanilla extract
- 3 cups all-purpose flour
- 1 tablespoon baking powder
- 2 teaspoons baking soda
- 1 pint sour cream
- 1 (12 ounce) bag semisweet chocolate chips
- Preheat oven to 350 degrees F (175 degrees C). Grease a 9×13-inch pan.
- Beat sugar and butter together in a large bowl with an electric mixer until light and fluffy; add eggs one at a time, thoroughly beating each egg into the butter mixture before adding the next. Add vanilla with the last egg.
- Sift flour, baking powder, and baking soda together in a bowl. Pour flour mixture alternately with the sour cream into the butter mixture, mixing until just incorporated. Fold chocolate chips into the batter. Pour batter into prepared pan.
- Bake in the preheated oven until a toothpick inserted into the center of the cake comes out clean, about 30 minutes.
