Preheat your waffle iron.
In a medium bowl, whisk together oat flour, flaxseed, baking powder, cinnamon, and salt.
½ cup oat flour, 1 tbsp flaxseed, 1 tsp baking powder, ½ tsp cinnamon, 1 pinch salt
In another bowl, whisk eggs, Greek yogurt, milk, and vanilla until smooth.
2 large eggs, ¼ cup Greek yogurt, ¼ cup almond milk, 1 tsp vanilla extract
Combine wet and dry ingredients, stirring until just blended. The batter should be thick but pourable—add a splash more milk if needed.
Lightly grease the waffle iron and pour in the batter.
Cook until golden brown and crisp, about 3–4 minutes depending on your waffle maker.
Serve warm with your favourite toppings (e.g., Greek yogurt, nut butter, or fresh fruit).
