Preheat your oven to 350°F.
Grease and flour two 9-inch cake pans.
In a large mixing bowl, combine the cake mix, water, vegetable oil, and eggs.
Use a mixer on medium speed for about 2 minutes until well combined.
Fold in the semi-sweet chocolate chips, ensuring they are evenly distributed throughout the batter.
Pour the batter into the prepared cake pans evenly.
Spread it out with a spatula to make sure it's level.
Bake the cakes in the preheated oven for about 28 minutes.
Check with a toothpick inserted in the center; it should come out clean.
Remove the cakes from the oven and allow them to cool in the pans for about 10 minutes.
Then transfer them to wire rack to cool completely.
Once cooled, you can choose to frost or serve as is for a rich chocolate experience.
