First, gather all of your ingredients. The butter should be at room temperature, and the oven should be set to 350 degrees.
Then, sift the flour, baking soda and the corn starch together and set aside.
Next, cream the butter, vanilla and the two sugars together (not the 4 tablespoons of sugar for the dusting, hold that off to the side for now) – I usually do this for at least 5-7 minutes.
Add in the eggs one at a time. Then, add in the dry ingredients 1/2 a cup at a time and mix as little as possible.
Roll the dough into 1-inch balls, then roll in the mixture of 4 tablespoons of sugar with 1 tablespoon of cinnamon, ensuring the cookies are well dusted with the snicker mix!
Finally, finish by placing the round cookies onto a silicone lined baking sheet.
Bake at 350 degrees for 12-14 minutes. Then, let them cool for a few moments and eat up.
