Dark Chocolate Orange Shortbread

It feels very strange posting a recipe again since I feel like it's been ages since I have even cooked! I barely cooked, let alone baked while I was away. I baked these shortbread cookies a while back and they were delicious. I found them over at Two Peas and their Pod. These have a distinct orange flavor to them which just pairs wonderfully with the dark chocolate. Irresitable to me! Very simple too! One of these days I am going to start cooking from my cookbooks again! I always plan to try something new from them but along comes something that I've seen on someone else's food blog that I have to make......It almost makes me think I have Attention Deficit Disorder to food!!! Can't stay on track...always changing my mind when I see something new! Can anyone out there relate?!

2 sticks unsalted butter
1 tsp salt
Zest of 2 oranges
1 tsp vanilla
2 1/3 cups flour
1 cup dark chocolate, chopped into tiny pieces

Preheat over to 300F. Grease 2 9" cake pans.
Place sugar and orange zest in a bowl and rub the zest in using your fingers.
In a large mixing bowl cream together butter, sugar/orange mix, salt and vanilla.
Chop chocolate. You want the pieces a little smaller than chocolate chips.
Beat flour and chocolate with the butter mixture until well combined.
Divide the dough in half and press into prepared cake pans. Make sure each pan is even.
Smooth the surface and prick the dough with a fork.
Bake for 40 minutes until golden brown.
Remove and loosen edges with a knife. Wait 5 minutes, then carefully place the shortbread out onto a clean work surface. Using a pizza wheel or knife, cut into wedges while still warm.
