Oatmeal Chocolate Chip Walnut Cookies

I really need to practice making cookies.

But seriously.
I have cupcakes and layer cakes down.  Brownies? Check.  Biscuits, scones?  Super easy.  I can even do pie crust.
But cookies?  They're the first thing most kids bake!  The one thing that their moms will let them help with!  The foolproof dessert that can only get screwed up by not setting a timer!
I follow every direction, measure with extreme precision, set painstakingly exact timers...
And I CANNOT nail them!

I want to say I can blame my oven.  I probably need an oven thermometer so I can test what temperature "350˚" actually is.  And maybe I need to play with temperatures as well as times.

I'm just saying, for me, thick golden cookies that don't spread like the dickens are apparently a lot to ask for.
In the picture are the prettiest three cookies of nearly 3 dozen.  They just kept spreading and browning really quickly!
Grr.

At least they taste good!

Pretty will come with time.

I hope.

For now, I will accept any cookie tips and tricks that you lovely people have to offer me, and will also sit back with one of my poor dilapidated tasty cookies.

Oatmeal Chocolate Chip Walnut Cookies
adapted from these cookies

Ingredients:
1 cup (2 sticks) unsalted butter, at room temperature
2/3 cup granulated sugar
1 cup packed light brown sugar
2 large eggs, at room temperature
1 tsp vanilla extract
1 tsp unsulphured molasses
1-1/2 cups all-purpose flour
1 tsp baking soda
1 tsp sea salt
1 tsp ground cinnamon
2 cups old-fashioned rolled oats (not instant or quick)
1-1/2 cups chocolate chips
scant 1 cup coarsely chopped walnuts

Directions:
In the bowl of a stand mixer, or in a large bowl with a very sturdy hand mixer, cream together the butter and sugars until very light and fluffy - about 5 minutes.
In a separate bowl, combine the flours, baking soda, salt, and cinnamon, whisking together thoroughly until no clumps of baking soda remain.  Stir in the oats, raisins, and pecans.
Returning to the mixer, add the eggs to the butter and sugars one at a time, beating well after each addition.  Stir in the vanilla extract and the molasses.  Gradually add the flour and oat mixture on a low speed to the creamed butter mixture until well combined.
Chill the dough, covered, for a few hours or overnight - optional, but recommended.
To bake the cookies, preheat the oven to 350˚F.  Line a baking sheet with parchment paper, a silicone baking mat, or (in a pinch) foil sprayed lightly with cooking spray.  For giant cookies, (cause who doesn't like a giant cookie??) drop the dough in 1/4-cup sized* balls spaced evenly on the baking sheet.  Place in the preheated oven on a rack centered in the oven.  Midway through the baking time, rotate the baking sheet so the cookies bake evenly.  If necessary, flatten the domes of the cookies with a spatula.  Bake the cookies for 20-22 minutes, or until the tops are just starting to brown - don't overbake them!  You'll be sad.  Remove from the oven, cool completely on a wire rack, and enjoy!
