In a medium mixing bowl, combine the flour, baking powder, salt, and sugar, and stir to combine.

Make a well in the center of the dry ingredients, and add the eggs, oil, and buttermilk.

Whisk all ingredients together until a thin and slightly lumpy batter forms.

Pour the batter into your waffle iron according to manufacturer's directions.

When the waffle is done cooking, carefully place it on a wire rack to cool, taking care not to stack the waffles on top of each other. Repeat with remaining batter.

Serve waffles hot with your favorite topping, such as buttermilk syrup, strawberries, and whipped cream.
