How to Properly Measure Ingredients: Use the appropriate measuring cups for dry ingredients and wet ingredients. Level off flour and sugar with a flat edge for accuracy.
Mixing Wet and Dry Ingredients Separately: Whisk together the flour, baking powder, sugar, and salt in one bowl. Combine the milk, melted butter, vanilla extract, and egg yolks in another bowl.
Avoiding Overmixing for a Light, Fluffy Texture: Slowly mix the wet ingredients with the dry ingredients. Stir gently until just combined. It’s okay if the batter has a few lumps—overmixing makes waffles dense.
Letting the Batter Rest: Why It Matters: Let the batter rest for 5–10 minutes. This helps the gluten relax and activates the leavening agents, making the waffles light and airy.
