Continue to whip for 4-5 minutes until thickened and fluffy.Reduce mixer speed to low, and slowly pour the sugar syrup into the bowl (between the whisk and the sides of the bowl to avoid splattering) until all has been added.Remove from heat and make sure egg whites are whipped to medium peaks. Continue to cook sugar until thickened to a corn syrup consistency, and the temperature on a candy thermometer reaches 235 F.

To prepare the marshmallow filling: bring ¼ cup water, corn syrup, and sugar to a simmer in a small pot.Remove from heat cool to room temperature before using. Stir in heavy cream and bring to a simmer. To prepare the caramel filling, place caramels and 2 tablespoons of water in a small pot over low heat, stirring occasionally until melted.Cool baking sheets at least 10 minutes between rounds before repeating with remaining dough. Use the parchment paper to slide the cookies onto the countertop to cool.Bake 2 sheets at a time for 8-10 minutes until golden brown, rotating baking sheets from top to bottom halfway through baking.Top with a baking sheet or the bottom of a pot and press again for an even finish. Place a sheet of parchment over the cookie dough, and press evenly to flatten to a 6-inch circle. Use a 4-ounce scoop or ½ cup measure to portion 1 ball of cookie dough onto the center of each baking sheet.Fold in M&M's and pretzels (reserving 1 tablespoon of M&M's and a few pretzels for decorating). Add flour, salt, baking powder, baking soda, vanilla, chocolate chips, and toffee bits (reserving 1 tablespoon each of chocolate chips and toffee bits), and beat until a dough forms.Add eggs one at a time, mixing to combine between each addition. Beat butter and sugars on low to medium speed until light and fluffy, about 2 minutes.Line at least 2 standard baking sheets with parchment paper set aside. For the cookies, preheat the oven to 375 F.Add the flour, corn powder, corn flour, salt, baking powder, and baking soda and paddle on low speed just until the dough comes together, no longer than 1 minute.Add the egg and mix until smooth, about 1 minute.

(No stand mixer? Elbow grease and a spoon work just fine.) Scrape down the sides of the bowl. In the bowl of a stand mixer fitted with the paddle attachment, cream together the butter and sugar on medium-high for 7 minutes.1 stick (8 tablespoons) unsalted butter, softened.Bake one for your next soirée and have mall-food-court cookie cakes across the country quaking in your wake.
