Mix the pumpkin, brown sugar, pumpkin pie spice, cinnamon and milk in a bowl, until combined. Taste test to get your desired flavor... more or less sweet, etc.
Butter 2 pieces of bread really well! The more, the better!
Place the butter side down in the pie maker. Then scoop some pie filling into the center. Add the other piece of toast on the top.
Close the pie maker.. extra bread will hang out of the side, but will fall off in the fire.
Cook over the fire until golden brown. Turn periodically, so it doesn't burn.
