peppermint squareos

DUDE. Homemade oreos. Like whoa. DO IT. These are the best cookies I've made in a really long time. You'll be sad if you don't make them.

And you know what's a lot easier than cutting circles of dough? Cutting squares.

For the Cookies:
3/4 cup sugar
1 1/2 cup plus 3 tbs all-purpose flour
3/4 cup plus 1 tbs unsweetened cocoa powder
1/2 tsp baking soda (or baking powder)
1 1/2 tsp salt
1/2 tsp instant coffee
15 tbs unsalted butter (2 sticks - 1 tbs!), cut in 1/2-in cubes, at room temperature (this is important)

For the Filling:
1/2 cup heavy cream
8 ounces white chocolate, finely chopped (I did half white and dark)
1/8 to 1/4 tsp pure peppermint extract (taste your dough as you add)

For the cookies:

Heat oven to 350 F.

In a bowl, combine the sugar, flour, cocoa powder, baking soda, salt, and instant coffee and mix. Slowly add the butter a few pieces at a time, stirring as you go. The mixture will have a sandy texture at first and then will begin to form pebble-size pieces. As soon as the dough starts to come together, stop the mixer. It will look wet, but loose. Squeeze a handful. It should hold together.

Roll the dough straight from the mixer. The dough becomes hard to work with if chilled.

Transfer the dough to a board and shape the dough into a block about 5 by 7 inches. Cut the block into two pieces.
One at a time, roll each block of dough between two pieces of lightly floured parchment paper until about 1/8-inch thick. Use a cookie cutter or a knife to cut out your shapes of choice.

Place on baking sheet lined with parchment paper. These cookies don't spread.

Bake for 10-15 minutes, pending on the size of your cutouts. Remove from the oven and cool on the sheets for 2 to 5 minutes. They'll be too soft to move straight from the oven. Transfer the cookies to a cooling rack and let cool completely.

For the Filling:
In a small saucepan, bring the cream to boil over medium heat. Remove from the heat and add the finely chopped chocolate and peppermint extract. Make sure all the chocolate is covered by the cream. Let stand for 1 minute (this is important), then whisk the white chocolate until completely melted.

Transfer the filling to a small bowl and let stand until room temperature. You’ll need the filling thicker to assemble the cookies, so cover the filling and place it in the refrigerator for 30 minutes or an hour, until a thick consistency is reached. If the filling hardens too much, it can be rewarmed in the microwave for a few seconds.

To Assemble the Cookies:
Place half of the cookies upside down on a work surface. Whip the filling lightly with a whisk to loosen it. It will lighten in color and fluff up. Don’t overwhip or the filling may begin to separate.

Transfer the filling to a pastry bag fitted with a 1/4-inch plain tip. Or just spread it on with a knife. Pipe or spread filling in the center of each upside down cookie. Gently, using your fingers, press the cookies together until the filling comes just to the edges. I had plenty of leftover filling for bowl licking enjoyment.
