Preheat mini heart waffle iron. Whisk eggs, milk, oil, and vanilla extract in a large bowl. Add in the flour, sugar, baking powder, salt, and cinnamon, and stir until all ingredients are combined.
Spray preheated mini heart waffle iron with a non-stick cooking spray. Pour waffle batter onto the hot waffle iron. Cook until golden brown.
Top with blueberries & strawberries, powered sugar, and maple syrup (if desired). Enjoy!
