Heat oven to 350°F Line large baking sheet with parchment paper or grease with shortening. Combine first 5 ingredients and set aside. Using electric mixer, cream sugar and butter until smooth and fluffy. Beat in vanilla. Add eggs one at a time and mix well. Mix in reserved dry ingredients. Stir in mini chips and toffee bits.
Spoon dough into 2 log-shaped pieces on prepared baking sheet.
Using oiled hands, shape into strips that are 11 1/2 inches long and 3 inches wide. Space them on baking sheet 3 inches apart. Bake at 350°F for 40 minutes.
Remove from oven and let sit for 5 minutes. Turn oven down to 325°F Remove parchment paper and place strips on cutting surface. Using serrated knife, cut ends of each strip on a diagonal to create an even edge.
Then continue to cut each strip diagonally into 1/2 -inch slices. Place slices back onto baking sheet cut sides up. Bake at 325°F for 15 more minutes, until crisp. Remove from oven and cool completely. Store in airtight container.
