Whoa, he's getting a little heated, hot enough to brown some butter for us.

Okay, Jack Jack, simmer down.

Thank you.

Next, take your cooled brown butter and mix in your sugar and salt until light and fluffy.

Looks like Jack Jack is getting in the mix too.

Whoa, thanks, Jack Jack.

In the same bowl, mix in a whole egg, an egg yolk, and some vanilla.

Add your remaining dry ingredients.

Oh, oh.

Sorry, Jack Jack.

And mix them in, along with some delicious chocolate chips.

Way to go, supers.

Once you've got your cookie dough all combined, scoop out some evenly sized dough balls.

You've got to have enough cookies for all your duplicates.

Perfect.

Let these dough balls chill for at least an hour, overnight if possible.

Luckily, we've got a friend who can help speed things up.

Thanks, Frozone!

It's finally time to bake the cookies.

Time for a Jack Jack snack attack.

If you want to make cookie num-nums at home, here's the recipe.

Enjoy.
