Preheat the oven to 325° before lining a 9 x 13 baking pan with parchment paper, leaving a little parchment overhanging the pan. It can helpful to slightly butter the baking pan to make the parchment sticks down properly.
Start by chopping the chocolate, pecans and dried cranberries. Once chopped, combine them with the sliced almonds in a bowl.
Next, mix together the butter, brown sugar and powdered sugar until smooth. Beat in the vanilla extract.
To the butter mixture, add in the spelt flour, all purpose flour, salt, orange zest, and Constant Comment tea from one cut open teabag (or 1 tsp of loose leaf tea). Mix until the shortbread mixture is evenly moistened and resembles clumpy sand.
Blend in the chocolate, nuts, and chopped dried cranberries. Transfer the mixture to the prepared paper lined pan. Using the bottom of a measuring cup (lightly floured on the base if needed), press into a single layer. Next, cut the dough with a sharp knife into at least 15 bars (5 by 3) and sprinkle with crystal sugar.
Bake for 45 to 50 minutes or until deep golden brown. Remove from the oven and recut the bars along the same lines while the bars are still warm.
Use the parchment overhang as handles to lift the bars out of the pan and recut again if necessary. Enjoy warm or cool!
Keep the fall spice shortbread bars in an airtight container up to 1 week or in the freezer for up to 1 month.
