Preheat oven to 350 degrees and line two quarter sheet pans (or one half sheet pan) with parchment. 

In KitchenAid stand mixer, cream palm oil shortening or Earth Balance Buttery sticks. Once smooth and whipped, add eggs. Once fully combined, slowly add 1 cup water until all wet ingredients are incorporated. (You can do this without a stand mixer, but you'll need a large bowl to do so.) 

Next add dry mixes. Allow machine to stir both until a moist batter is created. If needed, add extra water, one tbsp at a time, up to 3 tbsp. 

Finally, add bag of Enjoy Life chocolate chips. Mix until chips are fully incorporated. 

Divide batter evenly between two quarter sheet pans (or two 9x13 pans casserole dishes), or bake in one half sheet pan. Smooth out the top and give the pan a good tap or two (or 5) to evenly distribute batter. 

Place trays in a 350 degree oven and back for 20-25 minutes. I HIGHLY suggest rotating pans halfway through. 

Allow to cool completely before cutting and serving.
