Mix the flaxseed meal and water together and set aside so it can thicken
Melt ½ cup of the chocolate chips in a microwave. It will be under a minute. Set aside.
In a large bowl cream the butter and sugar together until it is fluffy. This will take about 3-5 minutes.
To the butter/sugar mixture add the flour, flaxseed meal mixture and the vanilla extract. Mix well.
Divide the dough in half.
Put one half of the dough in a smaller bowl and mix in the melted chocolate and mint extract.
Now you have a chocolate dough ball and a natural colored dough ball.
Lay out 2 large pieces of waxed paper (about 15-16" long each).
Lay one of the dough balls on a piece of waxed paper and flatten a bit.
Roll out to a 9" x 13" rectangle. You can keep cutting off the edge where it protrudes out of your shape and lay it where you need more dough.
Do this with the other ball of dough on the second piece of waxed paper.
Invert the chocolate rectangle onto the natural colored rectangle. This is tricky because you really can't move it once it lays down. They are pretty thin sheets and stick together.
In the photo above I have the white on the chocolate but I layed another piece of waxed paper on top and flipped it over.
Then I cut off the extra chocolate dough on the end and, okay I'll admit it, I ate it. Yum!
The chocolate tends to crack a bit as you roll so that is why you want to roll with the natural colored dough on the outside/underside. It is not this dough recipe specifically but all pinwheel chocolate dough tends to crack.
Peel off the waxed paper from the top.
Starting with the long side - roll the dough a bit firm so the dough touched but not tight.
Now you have a long roll. Cut in ¼" slices (or a bit wider is okay too).
Placed on an ungreased baking sheet.
They do not spread out much as they bake so they can be pretty close together. Like 1" at the closest.
Bake 10 minutes at 375 degrees.
Let cool 2 minutes and remove to a rack to cool completely.
You do not need to put a chocolate topping on them because they are delicious as they are but my husband wanted more chocolate so I did half of the cookies with a circular layer of chocolate on top.
If you want to put chocolate on top just melt the other cup of chocolate chips in a microwave and pipe on in a circular motion when the cookies are cooled.
