Preheat oven to 375F (my oven is awful, so I baked this at 400F) Grease an 8x8 in pan with coconut oil.
In a medium bowl, mix together almond milk and lemon juice. Let sit for 5 minutes.
In a large bowl, mix together oats, baking powder, spices and salt.
To the almond milk mixture, whisk in the egg, coconut oil and maple syrup.
Place half the oat mixture in the baking pan evenly, and layer with one cup of blueberries. Add the remaining oats, and then the remaining blueberries. Gently press down.
Pour milk mixture evenly overtop.
Bake in oven for 30-45 minutes until golden brown.
Serve immediately with a drizzle of maple syrup overtop.
