Preheat: Plug in your waffle iron and set it to medium-high heat. Preheating is essential. A hot waffle iron helps the waffles cook evenly and become crispy on the outside.

Grease Lightly: Once heated, spray the waffle iron with a light coating of cooking spray or brush it with a small amount of oil. This prevents sticking and makes it easier to remove the waffles.

Combine in a Bowl: In a large mixing bowl, add the flour, baking powder, salt, and sugar (if using).

Whisk Thoroughly: Use a whisk to blend these dry ingredients until they are evenly distributed. This creates the base of your waffle batter and ensures even rising during cooking.

Prepare Your Liquid: In another bowl, pour your milk substitute. You can use water, almond milk, oat milk, or coconut milk as a replacement for dairy.

Add Oil and Optional Eggs: Stir in the vegetable oil. If using eggs or a flax egg, add them now. Mix until the liquid ingredients are smooth and well combined.

Incorporate Flavoring: If desired, add vanilla extract or a pinch of your favorite spices. These small additions enhance the overall taste of your waffles.

Gradually Add Wet to Dry: Slowly pour the wet ingredients into the bowl with the dry ingredients.

Stir Gently: Mix the two together until just combined. Avoid over-mixing; a few small lumps in the batter are acceptable. Over-mixing can lead to tougher waffles.

Check Consistency: The batter should be smooth and thick enough to hold its shape when poured. If it seems too thick, add a little more water or your chosen milk substitute.

Pour the Batter: Carefully scoop a portion of the batter onto the center of the preheated waffle iron. Typically, ½ cup of batter works well, but adjust according to the size of your waffle iron.

Spread Evenly: Use a spatula if needed to spread the batter slightly, ensuring it reaches the edges.

Close the Lid: Close the waffle iron gently. Do not press too hard, as this might affect the waffle’s texture.

Cook Until Golden: Allow the waffle to cook until it turns golden brown. This usually takes 3 to 5 minutes, depending on your waffle iron. The waffle is done when it is crispy on the outside and fluffy on the inside.

Release the Waffle: Carefully lift the lid and remove the waffle using a fork or tongs.

Cool Briefly: Place the waffle on a wire rack for a minute. This step helps maintain its crispness.

Repeat the Process: Continue with the remaining batter, re-greasing the waffle iron lightly before each batch if necessary.

Inspect Your Waffles: Once all waffles are cooked, check that they have a consistent texture. The edges should be crisp, while the center remains soft and tender.

Serve Warm: For the best flavor and texture, serve your waffles immediately after cooking. If you need to keep them warm, place them in a low oven, but be aware that prolonged storage may affect their crispness.
