T's Spiced Slice and Bake Cookies

 

2 sticks of butter (1 cup), softened
1 ½ cups brown sugar
1 large egg
1 teaspoon vanilla
3 cups all-purpose flour
1 teaspoon baking powder
1 heavy teaspoon ground cinnamon
1 teaspoon ground allspice
1/2 teaspoon salt
1/2 teaspoon ground cloves
1/2 teaspoon ground nutmeg

Preheat the oven to 350 degrees.

In a separate bowl, combine the flour, baking powder, cinnamon, allspice, salt, cloves, and nutmeg. 

Put butter and brown sugar in the food processor and process until well mixed.  Add the egg and mix well. While the machine is running add the vanilla.  Remove the top and add in dry ingredients, pulsing just until mixed and the dough starts to form into a ball.  

Scoop dough out onto a sheet of plastic wrap and form dough into a log. Chill dough for at least 1 hour.  Slice dough into 1/4" slices, place cookies 2" apart, and bake on a parchment-lined baking sheet.  Bake cookies for 10-12 minutes or until light brown around the edges. Cool on a metal rack.
