Transfer the fully combined cookie dough to your prepared 9x13 pan. Use a spatula to spread and press down the dough into an even layer. Add additional candies on top (press them a bit down into the dough).
Place your 9x13 pan onto the middle of your oven's center rack and bake at 350°F (175°C) for 35 to 40 minutes, or until the top is golden and no longer raw in appearance. Use a toothpick to insert in the center to check for doneness.
Remove from oven and allow to cool completely before removing and cut into squares. Serve and enjoy.
