Step 1

In a large bowl, whisk flour, cornstarch, baking powder, baking soda, and salt.

Step 2

Add egg, vanilla and buttermilk to the bowl with the wet ingredients.

Step 3

Mix until just blended. It’s ok if the batter is a little lumpy. Add more buttermilk as needed if the batter is too thick.

Step 4

Heat a waffle iron and spray or brush with oil. Pour batter into waffle iron and cook according to manufacturer instructions.

Step 5

Remove waffle from waffle iron. Serve with maple syrup, fruit, nuts, or yogurt.
