Preheat oven to 375 F. Grease two 9" square baking dishes.
Mix together the oats, cinnamon, nutmeg, baking powder, and salt.
In another, mix the almond milk, maple, flax eggs, vegan butter, vanilla, banana, ginger, and carrots. Mix into the dry ingredients.
Fold in the walnuts, raisins, 3 tbsp hemp hearts and candied ginger.
Transfer mixture to the two baking dishes. Sprinkle with hemp hearts. Bake for 22-25 minutes or until golden brown on the outsides and firm to the touch. Allow to cool before cutting into pieces.
Meanwhile, in a food processor, puree the yogurt, cream cheese, lemon juice and sugar until smooth. Transfer to a piping bag and drizzle on top of the baked oatmeal. Enjoy at room temperature.
