This my kids' decided unanimously was their version of chocolate chip cookies.  They do not appreciate my cake like ones but these gooey, soft kind are their favorites.  They will not look done at 7 minutes but take them out anyway and let them sit on the pan for 1 minute.  When they cool they will be perfect.  This is based off of my friend Brenda's recipe.

1 c butter
1/2 c white sugar
3/4 c brown sugar
2 tsp vanilla
1 egg
1 tsp baking soda
1 tsp salt
2 tsp corn starch
1/2 c peanut butter
2 1/4 c flour
2 c milk chocolate chips

Beat the butter and sugars together till light and fluffy.  Beat in the vanilla and egg and then the rest of the ingredients.  Cook in 1 1/4 inch balls at 375 degrees for 7-8 minutes.  Cool on cookie sheets for at least a minute before moving to a wire rack.
