Preheat the oven to 350 degrees F.
Line a cookie sheet with parchment paper.
In a large bowl, cream together butter and sugars with an electric mixer.
Add the remaining wet ingredients and mix well.
Next, combine the dry ingredients and add them to the bowl.
Mix at low speed until a soft dough forms, scraping down the sides of the bowl as needed.
Add your favorite mix-ins and combine well.
Use a large cookie scoop to form dough balls the size of small limes.
Place the cookie dough balls on the lined baking sheet at least 2" apart. Press the ball down with your fingers so that it's about an inch thick.
Bake cookies at 350 F for 15-18 minutes or until the edges of the cookies start to turn golden brown.
Upon removing from oven, top with more sprinkles, add extra pretzels or M&Ms if desired.
Move to a wire rack to cool.
