Cream Chocolate Chip Cookies

I had cream left from the Momofuku's Crack Pie and I found this recipe on Roxana's Home Baking

Gabe was going out with Neil on the diveboat and I wanted to make a treat for the guys. Neil really likes cookies and ate his fair share while visiting us in Florida. It's a win- win for the both of us, he enjoys the cookies and I get to bake and try new recipes.

I thought I had instant coffee in the house. I searched everywhere for it. It was used up or I tossed it ( I know hard to believe). I didn't want to go to the store for one thing so I subbed vanilla for the coffee.

Ingredients:

1/2 cup room temperature butter
1/2 cup brown sugar
1/2 cup granulated sugar
1/4 cup heavy cream
1 egg yolk
1/2 tsp baking powder
2 cups all purpose flour
2 tsp instant coffee granules ( used 2 teaspoons vanilla)
1/4 cup chocolate chips ( didn't mix- used semi-sweet )

Directions:

Preheat oven to 350 degrees.

 Cream butter and sugar until light and fluffy in a large mixing bowl with a hand held mixer or mixer with a paddle attachment.  
Add the heavy cream and egg yolk to the mixture and beat well, scraping the sides of the bowl with a spatula.

Add the baking powder, flour and coffee granules or the vanilla and stir to combine. Fold in the chocolate chip with a wooden spoon or a spatula.

Roll the dough in a ball and wrap with plastic. Put it in the refrigerator for a half hour.

Place a spoonful on ungreased cookie sheet and bake for  12-14 minutes. When the edges begin to brown take them out.

Remove from the oven and let the cookies sit on the cookie sheet for about a minute and them remove and place on a wire rack to cool.

* I called Carol and asked her about this recipe. The batch of cookies I gave to Gabe for the boat were nice and soft. I added the additional cookies to a tin. The cookies in the tin were rock hard! I was frantic- I thought the cookies I gave to Gabe were hard also. When he got home he said the guys loved the cookies- I said I hoped they didn't break a tooth. He didn't know what I was talking about.

I gave him a cookie from the tin ( air tight) and he couldn't believe how hard they were. Strange. I baked them the same temp and time. 

The only thing I can think of I added the cookies to a plastic bag for the boat. I don't see how that would make a difference.

I've been making cookies for over 50 years and this has never happened and Carol couldn't figure it out either.

Anyone have any suggestion?

The thing to remember about the recipe- the guys loved them!
