Preheat oven to 350°F. Line a cookie sheet with parchment paper. Melt the butter and allow it to cool. Chop the pecans and set aside.
1/2 cup butter, 1/2 cup pecans
In a medium bowl, add in flour, oats, cinnamon, nutmeg (optional), cornstarch, baking powder, baking soda, and salt.
1 1/2 cups rolled oats, 1 cup all-purpose flour, 1 1/2 tsp cornstarch, 1/2 tsp baking soda, 1/4 tsp baking powder, 1/4 tsp salt, 1/2 tsp cinnamon, 1/8 tsp nutmeg
In a large bowl, whisk cooled butter, brown sugar, and white sugar. Add in egg and vanilla and whisk in.
1/2 cup butter, 1/2 cup dark brown sugar, 1/3 cup white sugar, 1 tbsp vanilla, 1 egg
Add in the dry ingredients and mix until a soft cookie dough forms. Don't over-mix!
Add in chopped pecans and toffee bits and mix in a few times.
1/2 cup toffee bits, 1/2 cup pecans
Scoop 6 cookie dough balls (about 1.5tbsp per cookie) and place on the prepared cookie sheet. Add an extra pecan on top.
Bake for 10-15 minutes. Mine took 13 minutes. The cookies will be ready when the edges are a golden brown, but the inside will look very soft. Remove from oven, let the cookies cool on the hot pan for a few minutes before serving warm or cool completely and enjoy!
