In large bowl, beat butter, sugar, brown sugar, and vanilla until light and fluffy. Add eggs, one at a time, beating well.

Slowly add flour, salt, and baking soda, beating until well blended.

Stir in chocolate chips by hand.

Spread in greased 9x13 cake pan. I love my Wilton 9x13 cake pan. Personally, I like to cover in foil and then grease the foil. It makes removing the cookie cake much easier.

Bake at 375 degrees F for 20-25 minutes. Cool cookie in pan on a cooling rack and then remove and place on serving platter.

Once the cookie cake is cooled completely, spread icing all over the cookie cake for a thin layer.

Seperate your red white and blue m&ms. Get the kids involved on this.

Add your rectangle of blue m&ms on the cake. My rectangle is 8 m&ms long and 6 m&ms tall.

Then begin your stripes. I did 2 rows of red, then 2 rows of white, then 2 rows of red, etc... You should end of up with 4 red stripes and 3 white stripes.

That is how easy it is! Get the kids involved to make this!
