Preheat the oven to 350° F (180°C).
In the bowl of a stand mixer, cream together the butter and sugars until smooth, light in color and fluffy. This will take a few mintues.
1 cup (222g) salted butter, 1 cup (246g) brown sugar, 1/2 cup (115g) granulated sugar
Scrape the sides of the bowl and mix in the egg add vanilla.
1 tsp vanilla , 1 egg
Once completely combined, stop the mixer and add in the flour, rolled oats baking soda and salt.
2 cups (304g) all-purpose flour, 1/2 cup (50g) rolled oats , 1 tsp baking soda , 1/2 tsp salt
Once the dry ingredients are almost mixed together, add in the toffee bits. Mix until completely incorporated.
1 8 oz bag toffee bits (I use the toffee bits with chocolate)
Portion out the dough into 3 tbsp portions (#24 scoop) and arrange on a parchment or silicone lined cookie sheet.
Bake at 350°F (180°C) for 11-13 minutes, or until the cookie dough has spread and the edges are turning golden brown.
Allow the cookies to cool on the pan for 10 minutes.
Serve warm.
