Preheat your mini waffle maker to ensure even cooking.
Mix dry ingredients – in a bowl, whisk together flour, baking powder, sugar, salt, and cinnamon.
Whisk wet ingredients – in another bowl, mix milk, egg, melted butter, and vanilla extract until smooth.
Combine – pour wet ingredients into the dry mixture and stir gently until just combined (don’t overmix).
Cook – lightly grease the waffle maker, pour in a small amount of batter (about 2 tbsp per waffle), and cook for 3-4 minutes or until golden brown.
Serve – top with your favorite toppings like fresh fruit, maple syrup, or whipped cream.
