In a blender or food processor, process Grape-Nuts until ground into a flour like consistency.
In a large bowl, combine ground cereal, flour, coconut palm sugar, baking powder, baking soda, cinnamon and salt. Add milk and eggs and stir until smooth. Let batter rest 5 minutes before using.
Preheat waffle iron to medium heat. Pour batter into the center of the lower grid. Close lid of waffle iron and cook for 3 1/2-4 minutes or until golden brown. Open lid carefully and remove baked waffle. Repeat with remaining batter.
Spoon Sweetened Maple Cream in to a ziplock baggie & with scissors snip a small corner. Drizzle over waffle and top with apple slices, pecans, and syrup. Dust with powdered sugar if desired. Serve immediately.
