Tie dye Cookie Bars

From my files - saved with this recipe so I could see what they look like, but it's not my picture.

I saw this recipe online some time last Spring and saved it to my collection to make - but since it was more the method than the recipe - I saved the images to remind me what to do - but I didn't copy down any instructions.  My site is for my 'collection' of recipes I've found to make or have made - (and my kids now that they are old enough to use it to cook and bake on their own) but I hope that some of the people popping in and seeing these will consider making them too as they are just so pretty!

Today is officially the first day of spring and I immediately thought of these pretty pastel bar cookies when I was thinking of something to celebrate the day, the start of the season and of course, Easter - right around the corner.

• Looking at the photos, I can see what to do and I saved the pictures in my files for that 'visual' instruction. (I didn't save any instructions - just the photos.) 
• You can see the idea is to choose 3-4 colors and pipe lines down your baked and cooled cookie bars. 
• Cover with clear plastic wrap.
• Press them very gently through the plastic to join them at the edges.
• Remove the plastic.
• Using a skewer, knife or other item, drag lines through the frosting from top to bottom.
• Cover with plastic again.
• Using your finger, draw down the scored lines to blend the edges again, blurring the lines and giving it a tye-dyed effect.

I hope the instructions make sense to my daughter or anyone else that may stop in to use some of the idea's and recipes on my site-collection.  You can use them on any bar cookie, but the simple sugar cookie style recipe is below the photos as it's a basic and easy recipe to use.

Sugar Cookie Bars

1 c butter
2 c sugar
2 t vanilla
4 eggs

In a large mixing bowl cream butter, sugar, and vanilla until fluffy and smooth. Add eggs one at a time, mixing well between each addition. Sift dry ingredients together and add to sugar mixture in small amounts. Mix batter until all flour is incorporated. Press into a 9X13 or 11X17" pan. Bake in 375 degree oven for 10-12 minutes.

Frosting

1 t salt
3 T light corn syrup
