In my last post, I mentioned putting off a take-home final to bake some special shortbread cookies. Now that I'm done with school, I am back to tell you all about these special treats!
First, a short story. A few weeks ago, my good friend from school called me up on a rainy Saturday and asked if I was home. "Uh, yes." I don't leave my house when it's raining unless it's absolutely imperative. "Great. I'm coming over. I have something for you," she said. Oh my gosh, the anticipation nearly killed me. Turns out she went to Surfas, a cooking and restaurant supply store in Culver City, and had a bag of edibles just for me! It's a testament to how well CK knows me that among the goodies she picked out were a pound of Plugra butter and these milk chocolate disks.
So, when I decided to bake something earlier this week, I decided to make something that would put that butter and chocolate to good use. I found the recipe for these bar cookies in the Flour Bakery Cookbook, and although the original recipe includes just raspberry filling, I felt confident that chocolate would be a welcome addition. It's very nearly impossible to go wrong with raspberry and chocolate, don't you think?
I really loved these cookies, but I also consider shortbread my Achilles heel. When I lived in Japan, the snack kitchen stocked these Walker's Shortbread Finger Cookies, which are about as close as you can get to eating a stick of butter without people giving you a funny look. I was so addicted to these that one time I opened a packet of cookies at my desk with such vigor that a waterfall of crumbs spilled all over my laptop keyboard. I'm not sure I should have admitted that publicly, but there you go.
Anyway, back to the task at hand... I also found the recipe intriguing, because the crumble topping is achieved by freezing a portion of shortbread dough, grating it using a cheese grater, and sprinkling it on top of the filling layer. I've never seen a crumble top like this, so naturally, I had to try it.
This whole exercise required some patience, but I think the results were worth the effort. I'm even thinking of making these again when I get home, because I think they're great holiday cookies.
Also, this recipe requires trimming the browned edges of shortbread once it is entirely baked. You can bet that I nibbled on these bits over the course of the night. If you even try to tell me you wouldn't do the same, I don't think we can be friends anymore.
Raspberry-Chocolate Crumb Bars, adapted from the Flour Bakery Cookbook
1 1/2 cups unsalted butter
1/2 cup granulated sugar
3 tablespoons confectioners' sugar
2 egg yolks
1 teaspoon vanilla extract
1 1/4 cups unbleached all-purpose flour
1 1/2 cups cake flour
3/4 teaspoon baking powder
3/4 teaspoon kosher salt
1/1/2 cups raspberry jam (with seeds)
3 tablespoons half-and-half
1/2 cup chocolate chips
1/4 cup confectioners' sugar (for dusting)
To make shortbread:
Cream together the butter, granulated sugar, and confectioners' sugar until the mixture is light and fluffy.
Beat in the egg yolks and vanilla on medium speed for 2 to 3 minutes, or until thoroughly combined.
In a medium bowl, sift together the all-purpose flour, cake flour, baking powder, and salt. Gradually add the flour mixture to the butter-sugar mixture and then mix until the flour mixture is totally incorporated and the tough is evenly mixed.
Scrape the dough onto a sheet of plastic wrap. Remove one-fourth of the dough to a separate sheet of plastic wrap. Wrap the remaining three-fourths of the dough entirely in the plastic wrap, pressing down to form a disk about 8 inches in diameter and 1 inch thick. Refrigerate the dough disk for about 30 minutes, or until the dough has firmed up but is still somewhat pliable. Pat the reserved one-fourth of the dough into a small disk, wrap in plastic wrap, and place in the freezer for at least 2 hours, or until hard.
In a small sauce pan, melt the chocolate chips and mix in the half-and-half until smooth. Set aside to cool.
Heat oven to 350 degrees F.
Lightly flour the 8-inch dough disk and two large sheets of parchment paper. Place the dough between the sheets of parchment, and roll it out into a rectangle about 13 by 9 inches and 1/4 to 1/3 inch thick. Carefully peel off the top sheet of parchment. Trim the edges so the rectangle has fairy neat sides. Transfer the bottom sheet of parchment with the dough to a baking sheet. Trim the parchment so that it fits the baking sheet.
Bake for about 20 minutes, or until the shortbread is light brown. Remove the shortbread from the oven, let cool for 10 to 15 minutes, then spread the melted chocolate on top of the warm shortbread. Add the raspberry jam on top of the chocolate layer, spreading it out evenly.
Remove the smaller dough disk from the freezer, and using the large holes on a box grater, grate it into large flakes. Evenly sprinkle the dough flakes over the jam.
Return the baking sheet to the oven and bake for another 20 to 25 minutes, or until the top is lightly browned. Let cool completely on the baking sheet on a wire rack.
When cooled, sift the confectioners' sugar evenly over the top. Trim the edges again, then cut into bars.
