Ingredients

  • 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 hemp seeds optional, for added fiber. Swap with chia seeds if desired.
  • 1-2 tablespoons plant-based protein powder optional for added protein.

  • 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.
