Turn on your waffle iron and let it heat for 3 to 5 minutes.

In a large mixing bowl, whisk together 1 cup mochi flour, 1 cup all-purpose flour, 2 tablespoons sugar, 2 teaspoons baking powder, and 1/2 teaspoon salt.

In a medium bowl, crack 2 large eggs and beat them lightly, then add 1 1/4 cups whole milk, 4 tablespoons melted butter, and 1 teaspoon vanilla extract.

Pour the wet mixture into the dry ingredients and stir until just combined.

Let the batter sit for 2 to 3 minutes.

Lightly grease your waffle iron if needed, then pour enough batter to fill it about three-quarters full.

Close the lid and cook for 2 minutes, then check and cook for an additional 1 to 2 minutes if needed.

Open the waffle iron and look for a deep golden-brown color on the edges.

Use a silicone spatula to gently remove each waffle from the iron and place it on a serving plate.
