Preheat your waffle iron and lightly grease it with butter or spray.
Brown the butter in a small saucepan over medium heat until golden and fragrant. Let it cool slightly.
In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt.
In a separate bowl, beat the eggs, then mix in buttermilk, vanilla, and malt syrup.
Slowly add the wet ingredients to the dry ingredients, stirring gently until just combined.
Fold in the browned butter until the batter is fully incorporated. Don’t overmix.
Pour the batter into the preheated waffle iron and cook until golden brown and crisp.
Serve immediately with toppings of your choice.
