In a medium bowl, cream the butter with an electric mixer on MEDIUM to break it up slightly, about 20 seconds.

Step 4

Next, add the sugars, and beat until light and fluffy, at least 1 full minute.

Step 5

Add the egg yolk and vanilla extract, and beat just to combine.

Step 6

Next, sprinkle the flour, malted milk, salt, baking soda and baking powder on top. (When you're adding them to the bowl, try to sprinkle them evenly over the top.

Step 7

Beat just until the flour mixture is combined.

Step 8

Stir in the chocolate chips by hand.

Use a large cookie scoop to make 6 or 7 large dough balls on your cookie sheet. Do not press or flatten out the dough balls.

Step 10

Bake the dough for 11-13 minutes, or until the edges of the cookies are starting to brown. They will deflate and crackle a bit as they cool.

Step 11

Let cool on the cookie sheet for 1 minute before moving to a cooling rack.
