Ingredients:
1. 500g Sponge Cake Powder
2. 330g Water
3. 1 Egg
4. 115g Vegetable Oil
Instructions:
1. In a mixing bowl, combine the sponge cake powder, water, egg, and vegetable oil. Whisk thoroughly until a smooth batter forms.
2. Preheat the bubble waffle maker to 340–350°F (170–180°C).
3. Lightly brush the waffle grids with butter.
4. Tilt the mold with one hand to hold it steady, and use the other hand to pour the batter evenly into the mold.
5. Close the lid immediately and flip the waffle maker over.
6. Set a timer for 5 minutes. While cooking, you can trim off any excess batter along the edges. When the timer goes off, flip back, open the lid, and remove the waffle.
7. Place the freshly baked waffle directly in front of a fan to cool for about 1 minute. This ensures a crisp exterior and a soft interior.
