Start by heating your oven to 375 degrees.

Then mix the flour, baking soda, and salt together in a bowl and set aside.

Use an electric mixer to beat the butter, sugars, and vanilla together. Once this mixture is creamy and smooth, add the eggs once at a time.

Slowly add the flour to the mixer, stopping to scrape down the sides of the bowl if necessary.

Then divide the dough into 4 smaller bowls. Mix ¼ cup chocolate chips, ¼ cup peanut butter, the rice krispies, and marshmallows into the dough in one bowl.

In another bowl stir together the nutella, white chocolate chips, and dough.

Next, combine the butterscotch chips, walnuts, ¼ cup chocolate chips, and dough.

Finally, add the remaining chocolate chips, ¼ cup peanut butter, and pretzels to the last bowl of dough and mix.

Use a large spoon to scoop up about 2 tablespoons worth of dough, roll it into a ball, and place it on an ungreased baking sheet. Space out the balls of dough leaving about 4 inches of dough between each one.

Bake the cookies for 9-11 minutes in batches using up all of the dough.
