Preheat the oven to 350°F. Take the 2 cans refrigerated crescent rolls out of their packaging and unravel both rolls onto a baking sheet (you may need to puzzle piece parts of the roll together to get it to fill the whole sheet!). Push the seams together so it forms one layer. Then prick the crescent roll dough with a fork so air bubbles do not form while baking.
Add the softened 16 ounces cream cheese, 1 cup mayonnaise, and 1 ounce ranch dressing mix to a stand mixer bowl and cream them together. Using a baking spatula, spread an even layer of the mixture onto the baked crescent roll dough.
