Turn on the oven to 350. and line your baking sheet with parchment paper.
Add butter, sugar, eggs, milk powder, and vanilla to a mixing bowl and mix until well combined, and fluffy about 2 minutes.
Add the dry ingredients to the wet ingredients, put a clean dish towel over the top of your mixer and mix on the lowest setting for 30 seconds, remove the towel and continue mixing on medium low until all the ingredients are well combined.
Use tablespoons for standard cookies and shape into a ball.
Place on a baking sheet with and bake in the 350 degree oven for 12-14 minutes.
If you want a chewier cookie I would bake them for 10- 12 minutes, if you want them more crunchy bake 14-15 minutes.
Allow to cool on the pan for about 10 minutes then place on a rack or enjoy warm!
