Preheat the oven to 350 degrees and line a baking sheet with parchment paper.
In the KitchenAid mixer, add the softened butter and sugar. Mix until creamy.
Add in the eggs while the mixer is mixing on low one at a time.
Add in the brown sugar and vanilla and mix until combined.
In a small mixing bowl, add flour, baking powder, baking soda and salt. While mixing on low, slowly add in the dry ingredients.
Remove the dough from the mixer. Add in the chocolate chips and chopped pretzels and fold into the dough.
Spoon about 2 tablespoon of dough onto the baking sheet at a time. Make sure they are spread out because the cookies will expand.
Bake 12-14 minutes.
Remove the cookies from the baking sheet immediately and place them on a cooling rack. Place a few extra chopped pretzels on top to garnish. Allow cookies to cool for about 5 minutes before serving.
Notes
Save extra cookies in a cookie container or dessert stand for up to 2 weeks.
