Ingredients

  • 3 large eggs sub 3 flax eggs for vegan – combine 1 tbsp ground flax seed + 2.5 tbsp water for each egg.
  • 1/3 cup unsweetened applesauce or mashed ripened banana. 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 ground flax seeds optional, for added fiber. Swap with hemp seeds, chia seeds or plant-based protein powder if desired.
  • 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 blueberries 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.
