  • How does cornstarch help a cookie?

    I was looking thru some cookie recipes and found a chocolate chipe cookie that has 1 cup of cornstarch in it. The recipe sounds interesting, but I was wondering why so much cornstarch.

    Thanks for any insite to my question.

    The only insight I have is that it must be taking the place of flour.  Without seeing all the ingredients it is next to impossible to make an intelligent guess, or even a dumb one...  which is more up my alley..Embarrassed

    Someone posted a recipe on here that also called for cornstarch. But only a spoonful, if I remember right. It was said (and T&T) to make the cookies softer and "fluffier". Why your recipe calls for so much, I have no clue. Does it replace the flour?

    Here's the recipe:

    Famous Cookies

    1/2lb butter

    1 cup brown sugar

    1 cup sugar

    3 eggs

    3 cups Bisquick

    1 cup cornstarch

    1/2 cup non fat milk powder

    2 TBS coffee powder

    1TBS cocoa

    1 TBS vanilla

    1 pkg chocolate chips

    4 oz chopped peacons

    Beat butter till fluffy, add sugars and eggs, then rest, except for chips and nuts. Stir them in. Bake grape size pieces in 350 oven for 14 minutes.

    That's the recipe.

     It is an interesting recipe,I have to agree. Cornstarch is used to make it lighter. I don't know,why so much. I never have made a cookie with Bisquick. I hope somebody will try it. I will try it later,but I am busy at the moment making plum cakes and a plum pie.

    Kathy,thank you for posting the recipe.

    The only cookie recipe I ever saw that has corn starch in place of some flour is the Heavenly Shortbread recipe that was on the Canada Corn Starch box in the early 1900's. It is the lightest airiest short bread I have ever eaten. I wouldn't think of using any other recipe. Try it and see if it isn't lighter.

    Sorry this is only a guess but it is what I know about the subject since I am not a baker person. Big Smile






    Here you go aubie2, enjoy! I also sent you a personal message.

    This recipe was posted here on the bb a long time ago.

    I use my Cuisinart to mix them because it is a stiff dough but as soft as a baby’s bottom when mixed.

    My sister does them in her KitchenAid mixer all the time.


    “Heavenly Shortbread”



    1/2 cup corn starch
    1/2 cup powdered sugar
    1 cup flour
    3/4 cup butter, softened

    Sift together the dry ingredients. With a wooden spoon blend in butter until soft, smooth dough forms (I used my Kitchen Aid for this and it worked well). Shape into 1 inch balls. If dough is too soft to work with cover and refrigerate for 30-60 min. Place 1 ½ inches apart on an ungreased baking sheet, flatten lightly with a fork, bake in 300° F for 15-20 min on until lightly brown.

    You can also roll out the dough to ¼ inch thick and cut out cookies.

    *I press mine into little cookie moulds I got at Wal Mart at Christmas time. You can dip these into chocolate too but I like them as is.

    I love baking and am very interested in the science behind baking.  From what I have read, cornstarch does not have gluten.  Also, using the right blend of corn starch and flour produces a softer shortbread cookie than when using flour alone.

    I forgot to finish, frost each cookie and enjoy.

    God Bless,


  • Re: How does cornstarch help a cookie?

    Cornstarch, or corn flour as it is sometimes called, is FLOUR.  So when  the cookie recipe calls for this, it is in place of wheat flour that is normally used.  Cornstarch, when used as a flour replacement, produces very light, delicate cookies that literally melt in your mouth.



  • Re: How does cornstarch help a cookie?
    could you please post the shortbread recipe? Sounds good!
  • Re: How does cornstarch help a cookie?

    WOW! Thanks for everyones help. I saw the other post that someone else had started. I'm going to give the cookies a try, now that I know it's not a typeo.

    Thanks. Kathy

  • Re: How does cornstarch help a cookie?

     Very interesting thanks for asking I learned something new today.


  • Re: How does cornstarch help a cookie?

    The Shortbread Cookies are sooooo good! 

    Will have to try the other two.  Any lemon cookie with that much butter in it must be delicious!
