Diet Coke Cookies

Posted on

diet coke cookiesConfession time.  So many people ask me how I find time to decorate cookies with five kids ages 8 months to 12 at home.  Actually I really don’t have time to decorate cookies.  What I do have is Diet Coke!  And the hours of maybe 10:30 pm – 2 am once or twice a week if I am lucky and if sweet little baby girl decides to sleep through the night that time is mine.  All mine!  I just need a little help from my BFF – Diet Coke.  I have a problem.  I admit it!  I am a Diet Coke addict.  Is there a 12 step recovery program for this??  If so, I am totally signing up in 18 years when my youngest moves out of the house.  So Diet Coke recovery program I will see you in 2032ish?  I will be old!  Wait, my baby will be 18!  And no more Diet Coke?!  Sad, sad, sad.  Never mind the 12 step Diet Coke recovery program can wait.

So where am I going with this?  Oh ya, I was making these Diet Coke cookies for a friend and my sister Cathy asked me how many ounces of Diet Coke I drink for every Diet Coke cookie decorated.  I think it was 1 ounce Diet Coke for every one Diet Coke cookie I made.  Such a nice ratio.  I actually loved making 36 of these, and sipping about 2/3 of my 44 ounce tanker.  Very fun!  I don’t think I would be able to make a Diet Pepsi Cookie.  GAG!!!

Keep reading to see how I made these Diet Coke Cookies.

The Diet Coke cookie was born at CookieCon – yes!  A cookie decorating conference.  I went to a cookie decorating convention here in Salt Lake City.  Call me cray cray.  I don’t mind.  I can take it!  Anyhow  I was sitting at a table with a bunch of Utah girls and more than half of us had a Diet Coke next to our bags of icing and plates of cookies.  I really lack in creativity.  I do.  I’m just a kopykake cookier.  I really doubt I have made something 100% original, but I’m working on it, I am, I promise.  Please assure that creativity will come in time.  Well I took apart my bottle of Diet Coke for a template and made my first Diet Coke cookie.

It’s a bit sloppy, but I used a couple of napkins for the background and the best instagram filter I could find to improve the picture.  The “Diet” lettering is so tricky!  A friend saw this and wanted some for a “favorite things” bridal shower so I was given a second shot at the Diet Coke Cookie.

Step 1 : How to Make Diet Coke Cookies – Bake the cookies

Use whatever recipe is your favorite!  I am using my preferred sugar cookie recipe, found here.  Make sure you freeze the cut out shapes before baking so that the circles remain circle during the baking.  I decided to make the cookies about 3.5 inches – a bit larger than normal because I knew how difficult it would be to add the “Diet” onto the cookies.

Step 2 : How to Make Diet Coke Cookies – Prepare the icing

For these cookies I used Royal Glaze icing.  The recipe for royal glaze icing is found here.  You could also use regular royal icing.  The recipe for Royal icing is found here.

The following icings need to be prepared (at least one day in advanced if possible so the color has time to develop)

  • Black icing – thinned to outlining consistency (soft peak stage), placed in a bag with a PME size 0 tip, or the smallest tip you can find.
  • Gray icing (mix just a dot of black icing into white icing) – thinned to outlining consistency (soft peak stage) placed in a bag with a size 2 tip
  • Gray icing – thinned to flooding consistency (like honey) and poured into a plastic squeeze decorating bottle
  • Red icing (tulip red with just a drop of black icing added) – thinned to outlining consistency (soft peak stage) – placed in a bag with a size 1 tip.
  • Red icing – thinner than outlining consistency (like molasses) – for flooding the letters on the cookie

Once icing is ready and cookies are cooled you are ready to decorate the Diet Coke cookies.

Step 3 : How to Make Diet Coke Cookies – Decorate the cookies with icing

Now is the fun part!

From here I added the “Diet” to the logo.  This was extremely difficult.  Maybe it was my icing, or just the day, but I struggle to get this perfect.  Maybe next time I will try to paint the word “diet’ on because it was awful to add using a piping bag.  Next outline the “Coke” logo with a small decorating tip.  Immediately add the thinner icing to the letters and blend any bumps with a toothpick.  Allow the cookies to dry and that is it!
