Chocolate chip cookies- part 2

Can't you tell that I am obsessed with chocolate chip cookies? Yes, this time I got it all right. I chose the copy cat recipe of Doubletree's chipper. If you have stayed there, you must have sampled the delicious warm cookie they give you at check-in. Although, I have stayed there only once during which time I was pregnant, I remember the texture of the cookie. The recipe makes about 22 colossal cookies. I used walnuts instead of macadamias. But the cookies are almost gone since Friday 'coz I sent a huge batch of it to S's badminton club. The feedback is in and they have been given *****.

Here is the recipe:

1/2 cup rolled oats
2 1/4 cups flour
1 1/2 teaspoons baking soda
1 teaspoon salt
1/4 teaspoon cinnamon
1 cup butter, softened (No Substitutes!)
3/4 cup packed brown sugar
3/4 cup granulated sugar
1 1/2 teaspoons pure vanilla extract
1/2 teaspoon lemon juice
2 eggs
3 cups Ghiradelli semi-sweet chocolate chips
1 1/2 cups chopped walnuts or macadamia nuts
Preheat oven to 350 degrees.
Grind oats in a food processor or blender until ground fine.
Combine ground oats with flour, baking soda, salt and cinnamon in a medium bowl.
In a separate bowl combine the butter, sugars, vanilla and lemon juice and mix with mixer until combined.
Add the eggs and mix until smooth and creamy.
Stir the dry ingredients into the wet ingredients and blend well.
Add the chocolate chips and macadamia nuts to the dough and mix by hand until ingredients are well mixed.
Spoon rounded 1/4 cups full (yes, 1/4 cups!) onto ungreased, nonstick cookie sheet.
Place scoops of dough 2" apart.
Bake 16-18 minutes or until cookies are light brown and soft in the middle.
