Preheat the oven to 410 degrees.
In a bowl of a stand mixer add the butter and sugar.
Mix on low for 1 minute then move up to medium until light and fluffy, about 3 minutes.
Add eggs, and vanilla extract to the sugar mixture, with the mixer speed on low.
In a large bowl add cake flour, all-purpose flour, oats, cornstarch, baking soda, salt and cinnamon and whisk until combined.
Slowly add the dry mix into the sugar mixture, mix on low speed.
Add in the chocolate caramel, pretzels, and candy canes, mix on low until combined.
Cover the dough with plastic wrap and chill dough for 15-20 minutes.
Using a large cookie scoop, create the dough into large balls and place on the parchment or silicone mat covered baking sheet.
If you have a scale, have the dough balls be from 3.5 ounces - 4.0 ounces.
In a small bowl add the crushed candy canes and crushed pretzels, toss to combine.
Lightly press on top of the dough ball into the crushed candy cane bits, using your hands to flatten slightly.
Place only up to 5 cookies on one large cookie sheet.
Bake for 9-11 minutes or until golden brown on the top.
