Preheat the oven to 350°F. Line a baking sheet with parchment paper or a silicone baking sheet. Set aside a handful of the mix in to place on top of the cookie.
Beat the butter with the brown and granulated sugar. Beat on medium speed until well combined, 2-3 minutes until well creamed. Next, add the eggs, maple syrup, and vanilla extract and continue beating until well incorporated.
In a separate bowl, combine the remaining dry ingredients. Stir to combine and slowly add the dry ingredients into the dough, mixing on low speed until half the flour is incorporated. Add the chocolate chips, M&Ms and marshmallows and continue to beat until incorporated, increasing the mixing speed as needed to complete the dough. Next, loosely fold in the chopped Pop-Tarts with a spatula so they aren’t fully smashed into the cookie.
Using a large cookie scoop, portion out 2 scoops of dough (equivalent to 4oz), placing one on top of the other. No need to roll together. Place 3 inches apart on the prepared cookie sheet. Bake for 13-16 minutes. The center of the cookie should be slightly underbaked but not too gooey or shiny on top. Remove from the oven, fix misshaped cookies immediately then allow to cool on the baking sheet for 15 minutes before transferring to a wire rack to cool completely.
