I'm picking the winner of the Science Cookie Cutter Giveaway tonight, so don't miss your chance to win!
My mom got me a present ... it's the King Arthur Flour Cookie Companion. So, when I wanted to make something to bring to work with me, I decided to turn to it for inspiration.
In the book, there is a recipe for filled double shortbread. It is fulled with jam in the cookbook. I happened to have a can of poppyseed filling, so I used that. And since poppyseed goes so well with lemon, I put some lemon zest in with the shortbread dough.
Since the recipe is in the cookbook, I can't repost the exact recipe here. But, if you take a basic shortbread recipe, and put half of the dough evenly in the bottom of a pan (I lined mine with parchment paper), spread a layer of filling over it, then roll out the other half to be the same size (approximately) on a piece of saran wrap, and then flip the dough onto the top and make it even.
Bake for 40-50 minutes at 300 F, let cool slightly, and then slice into rectangles or triangles.
