1-First Step: Mixing the Batter Start by finding a large microwave-safe bowl. You want plenty of room because the batter will expand slightly as it cooks. Combine the glutinous rice flour, ground ginger, baking powder, salt, and packed dark brown sugar in the bowl. Whisk these dry ingredients together until they are well incorporated. Next, pour in the wet ingredients: the full-fat canned coconut milk, water, melted unsalted butter, and the large egg. Stir everything together until the mixture is mostly smooth. It is perfectly okay, and actually expected, to have some tiny lumps remaining. Do not overwork it trying to get it perfectly smooth like a conventional batter. The lumps will dissolve during the cooking process.

2-Second Step: The First Microwave Interval Place the bowl in the microwave and cook on high for 1 minute and 30 seconds. Once the timer goes off, open the microwave and give the batter a good stir. You will notice it starting to thicken already. This is the beginning of the transformation from a liquid batter to a mochi-like dough. Make sure to scrape down the sides and bottom of the bowl to incorporate any cooked edges into the center.

3-Third Step: The Second Microwave Interval Return the bowl to the microwave and cook for another 1 minute and 30 seconds on high. Remove it and stir again vigorously. At this point, the texture will be significantly thicker and more elastic. You might see some parts that look solid and others that are still runny. This is normal. The goal is to distribute the heat evenly so the dough cooks uniformly.

4-Fourth Step: Final Cooking and Cooling Microwave the mixture for a final interval of 1 minute and 30 seconds. By the end of this time, about 3/4 of the batter should have solidified. Stir the dough one last time to incorporate any runny portions into the cohesive dough. If it still looks too runny to scoop, heat it for an additional 30 seconds and stir again. Once you have a thick, sticky dough, set it aside to cool. Let it rest uncovered for 10 to 15 minutes. This cooling period is crucial because it makes the dough easier to handle and portion. If you try to scoop it while it is piping hot, it will be too sticky and might tear.

5-Fifth Step: Heating the Waffle Iron While the dough is cooling, get your waffle iron ready. Preheat it to medium heat. Because these waffles are high in sugar and starch, they can brown quickly, so medium heat is safer than high heat to prevent burning before the inside is cooked through. Grease the waffle iron plates thoroughly with butter, oil, or cooking spray. This is a sticky dough, so good greasing is essential to prevent it from sticking to the iron.

6-Sixth Step: Cooking the Waffles Once the dough has cooled and the iron is hot, it is time to cook. Portion the dough using a scoop, about 1/3 to 1/2 cup per waffle. A #16 scoop works perfectly for this. Place the dough in the center of the iron and close the lid. Cook for at least 4 minutes. You want them to be a deep golden brown color. Cooking times vary based on your specific waffle iron, so keep an eye on the first batch.

7-Final Step: Serving and Storing When the waffles are golden brown and crispy, carefully remove them from the iron. Transfer them immediately to a cooling rack. This step is important because placing them on a flat plate can trap steam and make them soggy. The cooling rack helps them stay crisp. Repeat the cooking process with the remaining dough. Store any leftovers in an airtight container to keep them fresh.
