Chocolate Chip Cookies

My manager and I had a discussion a couple weeks ago about these chocolate chip cookies. I've been having troubles w/ my go-to recipe ever since we bought a new oven. For some reason, I have no clue how or why, my cookies have been going flat. Like, so flat, the chocolate chips rise above the actual cookie. It's been depressing b/c they are still soooo good, but just flat. Very sad.
So I've been trying to find a recipe that I love just as much, but are big and fat and yummy. So she mentioned how she saw this chocolate chip cookie recipe on a blog she follows and tried them. First off, the recipe tells you to take 1/4 cup of the dough and cook those for 15-17 min, which is ridiculous to me since my cookies were like a small golf ball and baked for 10 min!!
Also, the ratio of the sugar was dif. And there was a LOT of sugar. The only other little things were that she used one egg and one egg yolk and melted the butter first.
Now I know Nemisah has good taste when it comes to desserts just based on past discussions we've had and treats she's made that I've had. So she sent me the recipe (she couldn't find the blog) and I tried them. Now she raved and raved and raved about them. She took them to her friend's house and he loved them. His wife loved them so much that when he made them she ate way too many and got a stomach ache.
This has got to be a no fail recipe, right?

WRONG!

So ok, they weren't bad but they weren't my chocolate chip cookies. The ones that my mom has been making since I was a little kid. The ones that I can recite to you from memory.
My mom ate them. My dad ate them. My boyfriend inhaled them. Like 10 of them (I used a smaller scoop, not the 1/4 cup). I had 2 before my stomach started hurting really bad...

I'm not the only one who was "meh" about them. Check out Kirbie Cravings for her review. She found them on allrecipes.com which is probably where the girl from the blog Nemisah read found them. It seems that recipe has been on there since 2004? Wow. Great reviews, but yeah. Meh.

I think it really just comes down to taste. I prefer a cookie that's more chewy and less sweet, rather than cakey and VERY sweet. I do think that I might try my recipe again, but maybe try it w/ melted butter. Probably not the egg yolk. I have a feeling that is what helped cause the cakeyness.

BTW, Nemisah said that they tasted very much like her batch, so I don't think I made them wrong...

Here is the recipe if you guys still want to try it:

2 c all purpose flour
1/2 tsp baking soda
1/2 tsp salt
3/4 c unsalted butter, melted
1 c packed brown sugar
1/2 c white sugar
1 Tbsp vanilla extract
1 egg
1 egg yolk
2 c semi-sweet choc. chips

Preheat oven to 325 degrees.
Sift together flour, baking soda and salt.
In a separate bowl cream together butter, sugars and eggs.
Stir in vanilla.
Add dry ingredients (1/3 of the mixture at a time) to wet ingredients until well blended.
Stir in choc. chips.
Line 17"x11" baking sheet with parchment paper.
Drop 1/4 cup of the dough on lined cookie sheet. 5-6 cookies per sheet.
Bake in 325 degree oven for 15-17 minutes. (I used a small batter scoop instead of a 1/4 cup and they took 15 mins to bake.)
Cool on cookie sheet for 2 minutes. Then transfer cookies to cooling rack.

They are super simple to make and it helps that the butter is melted so you don't have to wait for them to get to room temp. So try them and let me know what you think!
