Ingredients:

  • 1 1/2 cups (150 g) rolled oats (old-fashioned)
  • 1 large ripe banana (about 110–130 g peeled)
  • 2 large eggs (about 100 g total)
  • 1 teaspoon (4 g) baking powder
  • Pinch of salt (1/4 teaspoon) — optional
  • 1/2 teaspoon ground cinnamon or 1/2 teaspoon vanilla extract — optional
  • Nonstick spray or 1 teaspoon neutral oil — to grease waffle iron if needed

Instructions:

  1. Prep and preheat: Preheat your waffle iron according to manufacturer instructions and lightly grease if it is not nonstick.
  2. Make oat flour: Add the rolled oats to a blender or food processor and pulse or blend until they become a fine, flour-like powder (about 20–30 seconds).
  3. Combine wet ingredients: Add the ripe banana and eggs to the oat flour in the blender. Add the baking powder and a pinch of salt (and cinnamon or vanilla if using).
  4. Blend to a smooth batter: Blend until smooth and homogeneous, scraping down the sides once. Batter should be pourable but slightly thick; if too thick add 1–2 tablespoons water or milk, if too thin add 1–2 tablespoons ground oats.
  5. Rest the batter: Let the batter rest 3–5 minutes to hydrate the oat flour and thicken slightly.
  6. Cook waffles: Work in batches and pour the recommended amount for your waffle iron (usually 1/3–1/2 cup for a standard iron). Close the lid and cook until steam slows and waffles are golden brown and crisp at the edges (typically 3–5 minutes). Use a spatula to lift waffles onto a cooling rack to keep crisp if making several.
  7. Serve: Serve hot with your chosen toppings such as fresh berries, maple syrup, yogurt, or nut butter.
