Sift flour, baking soda, and salt together. Set aside.
In a mixing bowl, cream together the butter, brown sugar, and sugar until well blended. Add vanilla, egg, and egg yolk and mix until smooth.
Add dry ingredients just until blended. Stir in the chocolate chips, caramel bits, and pretzels. Refrigerate batter for at least 1 hour.
Preheat grill to 350 degrees. Place a pie pan upside-down on grill rack.
Line a baking sheet with parchment paper. Roll cookie dough into 2-Tbsp balls and place onto cookie sheet (you might need to press some of the goodies into each ball).
Place cookie sheet on top of pie pan on grill and grill for 10 minutes. Remove pan and let cookies cool on pan for 2 minutes.
Remove to cooling rack. When cool, serve them with DREYER'S Butterfinger Peanut Butter Cup and DREYER'S Baby Ruth ice cream and enjoy!
