Heat oven to 375℉. Line baking sheets with parchment paper.
Combine shortening, sugar, milk and vanilla in bowl of mixer. beat at medium speed until well combined. Add egg and mix until combined.
Add flour, salt and baking soda. Starting on low mix into wet ingredients just until completely combined.
Add chips and toffee. Stir in until well incorporated.
Using a medium cookie scoop, scoop dough onto prepared pans.
Bake time is 8-10 minutes depending on oven. I bake mine right at 9 ½ minutes.
The cookies should be slightly golden on edges and shine should be just gone from top. They will look slightly soft but will continue to bake slightly on the hot pan. Cool 2 minutes on the pan, then remove to cooling racks.
