Begin by preheating your waffle iron according to the manufacturer's instructions for even cooking.
In a large mixing bowl, whisk together the all-purpose flour, almond flour, sugar, baking powder, baking soda, and salt until smooth.
In another bowl, whisk together the low-fat buttermilk, eggs, melted unsalted butter, and almond extract until well combined.
Pour the wet ingredients into the dry ingredients and gently fold with a spatula until just combined, being careful not to overmix.
Fold in the sliced raw almonds, ensuring they are evenly distributed throughout the batter.
Grease the waffle iron and pour the recommended amount of batter onto it. Cook until golden brown and crisp.
Carefully remove the waffles from the iron and serve immediately with your favorite toppings.
