Vegan Triple Berry Sheet Pan Pancakes

1 Preheat oven to 425 degrees.
2 In a medium sized mixing bowl, combine the almond milk and apple cider vinegar. Let sit while you start the rest so it thickens a bit.
3 In a large mixing bowl, combine the flour, baking powder, and salt. Whisk together just to combine. Set aside.
4 Add the vanilla, maple syrup and oil to the almond milk mixture, and stir.
5 Slowly add the wet ingredients to the dry ingredients, whisking together until fully combined. 
6 Stir in the lemon zest if using. Pour into an 11x16in. sheet pan that is lined with parchment paper and sprayed with non stick spray. Smooth out the batter.
7 Bake at 425 degrees for about 5 minutes, then sprinkle the berries on top. Rotate and bake another 10-12 minutes, or until fully baked and tooth pick comes out clean. Then if you want to brown the top, you can broil at this point for 3-4 minutes or so until brown. Serve with maple syrup or powdered sugar or both!
