  • 3 flax eggs , to make the flax-eggs combine 3 tbsp ground flax seed + 7.5 tbsp water and let it sit until thick and gel-like. May sub regular eggs if not vegan.
  • 1/3 cup mashed ripened banana (1 small banana) , may sub with unsweetened applesauce or swap with pumpkin puree for low carb.
  • 1/3 cup pure maple syrup , or other liquid sweetener of choice, plus more depending on preferred sweetness – you can always serve with more maple syrup once baked. Use Lakanto Sugar-Free maple syrup or yacon syrup for lower sugar/low-carb.
  • 1 1/2 cups unsweetened almond milk or any other milk of your choice
  • 1 1/2 teaspoons pure vanilla extract
  • 1/2 tsp baking powder
  • 1 teaspoon ground cinnamon
  • 1 teaspoon hemp seeds optional, for added fiber. Swap with chia seeds if desired.
  • 1-2 tablespoons plant-based protein powder optional for added protein.
  • 3 1/4 cups gluten-free old fashioned rolled oats for grain-free + paleo-friendly oatmeal, swap oats with equal mix of roughly chopped coconut flakes and sliced almonds (about 1 3/4 cups of each).
  • 1/4 cup unsweetened shredded coconut plus more for topping. Omit if preferred or add ground flaxseeds, hemp seeds, chia seeds or plant-based protein powder.
  • 1 cup fresh mixed berries plus more for topping. If using frozen, be sure to thaw and drain the berries before getting started on your casserole. You may need to adjust the amount of liquid and cooking time.
