Roll the crescent roll dough with a rolling pin into an 8×12-inch rectangle. Cut the dough into 24 squares.
Place a square into each cup of a mini muffin pan and lightly press to form an indention into the muffin pan.
Spoon a teaspoon of the spinach dip mixture into the dough. Repeat until all of the dough has been used. Sprinkle with the remaining mozzarella and Parmesan cheese on the top.
Bake until golden brown and the cheese has melted, about 15 minutes. Remove from the oven and allow to cool in the pan for 5 minutes before transferring to a serving plate.
