I had to bring cookies to a church function. My husband recommended the Sierpinski Carpet fractal cookies shown on evilmadscientist.com. I thought the square shapes might be a little boring and decided to do Sierpinski triangle cookies instead.
I made them green and added peppermint extract. The recipes I used were:
1 1/4 cups all-purpose flour
1/2 cup unsweetened cocoa powder
1/4 teaspoon salt
1/2 cup butter, softened
1 cup white sugar
1 egg
for the chocolate part and
3 cups all-purpose flour
3/4 teaspoon baking powder
1/4 teaspoon salt
1 cup unsalted butter, softened
1 cup sugar
1 egg, beaten
1 tablespoon milk
for the green part. I didn't chill the dough at all because I wanted it flexible to work with. It was tougher than I thought it would be to shape the triangular logs of dough, but they look pretty decent for cookies.
I ended up with lots of scraps. I rolled them into a log and made swirled round cookies (I didn't want to waste the cookie dough).
Sadly, nobody at church even noticed that they were fractals. *sigh*
