1. Pre heat your oven to 350°
2. In your mixer combine butter, granulated sugar, milk powder, and brown sugar until light in color and fluffy about 2 -3 minutes. Scrape down the bowl.
3. Add in eggs and vanilla mix in again for about 2-3 minutes. Scrape down the bowl.
4. In a separate medium sized bowl combine the dry ingredients. The flour, baking soda, and salt.
5. Turn the mixer on low, and add ⅓ of the flour mixture until just combined, then repeat until all of the flour is well combined. Scrape down the bowl.
6. Add chocolate chips, and toffee chips. Mix until well incorporated about 45 seconds to 1 minute. Scrape down the bowl.
7. Add the Pretzels last. Mix until just combined, about 30 seconds.
8. Cover and Chill 30 min
9. Scoop 1 TBS scoops of cookie dough onto a baking sheet. Usually I can fit about 12 on my baking sheet, just make sure they are well spaced. I also use parchment paper, although it is optional.
Bake 9-11 minutes until browned around the edges.
Remove to cookie racks, to cool. Enjoy.
