Preheat the oven to 350F. Line a 9x13-inch baking dish with 2 pieces of parchment paper so it hangs over all 4 sides.
Add the oil, water, and egg to a large bowl and whisk together.
Add the yellow cake mix to the wet ingredients and stir to combine.
Stir in the chocolate chips (reserving 2 tablespoons for topping).
Transfer the batter to the prepared baking pan and spread it out evenly. Sprinkle the reserved chocolate chips on top.
Bake until the bars are starting to turn light golden brown along the outside, but still look a touch doughy in the center, about 20 to 25 minutes.
Cool fully to room temperature and then cut into bars.

The thickness of the batter should be fairly similar to the thickness of blondie batter.
For the best texture, be careful not to overbake. These bars set as they cool.
To make these bars even more decadent, use 1/3 cup melted unsalted butter instead of the water.
It’s not necessary, but to take the flavor of these bars to the next level, add 1 teaspoon vanilla extract to the wet ingredients, and once these are out of the oven, sprinkle 1 teaspoon flaky sea salt on top.
Once they’re cooled, store these bars in an airtight container layered between pieces of parchment paper at room temperature for up to 4 days or in the freezer for up to 3 months.
