Place the brown sugar and vegan buttery spread in a mixing bowl and mix on medium speed until smooth and combined.
Add the applesauce and molasses and continue to mix. Reduce the speed to low and add half the gluten free flour blend. Mix until combined.
Add the other half of the gluten free flour blend, salt, baking soda, and the spices. Mix on low speed until smooth and combined.
Divide the dough into two portions and pat into discs. Wrap each disc in plastic wrap and chill in the freezer for one hour, or the refrigerator for two hours.
Print out the pattern, and trace the shapes onto waxed paper. Cut out the waxed paper pattern pieces carefully. After the chilling time, get two cookie sheets out and set aside. Preheat the oven to 350 degrees.
Place a piece of parchment paper on your rolling surface, and dust lightly with gluten free flour. Place a chilled disc of dough on the waxed paper, and sprinkle flour on top. Dust a rolling pin with gluten free flour and roll the dough out until it reaches a thickness of about a quarter-inch (¼"). Place the pattern pieces on the dough and cut around them with a sharp knife. You can probably get two walls or two roof pieces out of each disc of dough.
Remove the scraps of dough surrounding the pieces, and carefully lift the parchment, with the walls or roof on it, and place on one of the cookie sheets. This is the best way to get the walls or roof to maintain their shape.
Repeat steps 7-9 until you get all the house pieces cut out.
Place the cookie walls and roof in the oven. Bake at 350 degrees for about 16-18 minutes. If you are doing two cookie sheets at the same time, rotate once during baking. Set aside to cool.
If you have extra dough, you can go ahead and cut out other cookie shapes to add to your scene, or just to eat separately. Try Christmas trees, deer, horses, cars, etc. If you can, allow the walls and roof to sit out uncovered for 8 hours or overnight. This will allow them to harden a bit, making them even sturdier.
