Instructions

• Preheat your waffle iron according to the manufacturer’s instructions; follow the manufacturer’s guidance for temperature and greasing if needed.
• In a bowl, whisk together ¾ cup all-purpose flour, ¼ cup cornstarch, ½ tsp baking soda, 1 tsp baking powder, and 1 tsp kosher salt until evenly combined.
• In a separate bowl, whisk together ¼ cup canola oil, ¾ cup buttermilk, 1 egg, 1 tbsp sugar, and 1 tsp vanilla extract until uniform.
• Pour the dry ingredients into the wet ingredients and gently stir with a spatula or whisk until just combined—no large dry streaks should remain; a few small lumps are fine. Do not overmix.
• Let the batter rest at room temperature for 15 minutes.
• When the waffle iron is ready, add the appropriate amount of batter per the manufacturer’s instructions and cook until the waffle iron indicates the waffles are done or about 2–3 minutes per waffle.
• Serve immediately, or keep waffles warm in a 250°F oven until ready to serve.
