First you will cream (mix) your butter, sugar and eggs together until they are smooth in one of your mixing bowls. Also preheat the oven to 350.
Next you will mix your flour, baking soda, baking powder, and salt together, then add the vanilla extract and mix well in your other mixing bowl.
Next you will slowly add your dry ingredients and milk to your creamed mixture and mix until smooth and until there are no lumps in it.
You then will add the vanilla pudding mixture into it.
Then you will grab your cookie sheet and spray it with nonstick spray.
Then grab your spoon and spoon batter onto the sheet evenly spaced and put in the oven for 10-11 minutes.
When your cookies are done take them out of the oven and let cool for a minute or two and then remove from the sheet and put on a plate.
Now you want to repeat steps 4-6 until you run out of batter.
