Begin heating up your waffle iron according to the manufacturer’s instructions.
In a large bowl, whisk together the oil, sugar, pumpkin, and vanilla until smooth. Stir in the flour, baking soda, and salt. Sift the spices, flour, baking powder, and salt into the bowl, and stir well, but be careful not to overbeat the batter. A few lumps are just fine. Finally, add in the oats, and mix just enough to distribute them equally through the batter.
Lightly grease your waffle iron before beginning to cook each round. Portion out as much batter in each waffle indent as you would for standard waffles, and spread it out lightly just to make sure it fills the space evenly. Shut the iron and cook for 2 – 5 minutes, depending on your waffle iron, until golden brown all over.
Transfer the hot waffle cookies to a wire rack. Repeat with the remaining batter. Once completely cool, prepare the ganache by microwaving the chocolate and soy creamer together in a microwave-safe bowl, in blasts of 30 seconds, stirring thoroughly until smooth. Use a spoon or piping bag to drizzle as desired.
Yield varies depending on the size of your waffle iron, but I got about 9 waffle cookies.
