Preheat oven to 350-degrees and line two cookie sheets with parchment paper and set aside. In the bowl of a stand mixer, affixed with the paddle attachment, add the butter and sugar. Mix on medium-high speed until fluffy. Add the egg and vanilla extract and mix until combined.

Change the mixer to low speed and add the dry pudding mix, flour, baking soda and salt. Mix until barely combined. Remove the bowl from the mixer and use a rubber scraper to ensure all of the ingredients are combined.

In a small bowl add 1/4 cup sugar. Use a standard sized cookie scoop to scoop cookie dough balls. Roll the balls in the bowl of sugar and place on the prepared cookie sheets. Baker cookies, one cookie sheet at a time, in 350-degree oven for 10-minutes. Allow cookies to chill and set on the cookie sheet for 10-minutes before transferring to a wire rack to finish cooling completely.
