Preheat oven to 350 degrees
In mixer bowl beat butter and sugar on medium-high until whipped together 1-2 minutes.
On low speed add in eggs and vanilla and mix until combined.
Add in flour, salt, baking soda, and baking powder and mix on medium until all combined.
Stir in chocolate chips and pretzel pieces.
(I saved a few pieces of chocolate chips and pretzels to top the cookies with) You can either mix them all in or reserve some pieces if you want to see the chocolate and pretzel pieces on top of the cookies.
On a parchment lined baking sheet drop, two tablespoons sized scoops of dough two inches apart so they bake evenly.
Bake at 350 for 8-9 minutes or until edges are lightly golden. Cool on a baking sheet.
