Prepare the cookie sheet and line it with parchment paper. Set it aside until it's time to bake the cookies.
Place the pretzel sticks in a Ziploc bag and lightly pound them with a rolling pin. Break the pretzels just enough to turn them into smaller pieces.
In a large bowl, mix together the cake mix, melted butter, and eggs. Keep mixing until it reaches a cookie dough consistency.
Fold in the smaller pretzel bits, caramel chips, and chocolate chips.
Roll the cookie dough into about 1 ½ inch balls. Place them on the cookie sheet, leaving approximately 1-2 inches of space in between each cookie dough ball.
Bake the cookies in a 350°F oven for 8 to 10 minutes.
Let the cookies rest. Transfer them onto a wire rack and let them rest for at least 5 minutes.
