Grease your waffle iron and preheat for about 3-5 minutes.
In a large bowl, whisk the flour, sugar, baking powder, and salt together.
2 cups (296g) gluten free flour blend, 3 tablespoons granulated sugar, 4 teaspoons baking powder, 1 teaspoon fine sea salt
Add the milk, oil, and vanilla and stir until incorporated. A few lumps in the batter is OK. Allow the batter to sit at room temperature for at least 10 minutes.
Using ¼ cup of batter at a time, pour batter onto hot waffle iron. Cook each waffle for 4 minutes. For best results, serve warm.
Notes
Feel free to use any milk you like, including non-dairy milk.
This recipe yields 12 mini waffles (measuring 4 inches each). You can use this recipe with a standard waffle iron for larger waffles, you will just end up with less of them.
