- Begin by whisking eggs and sugar in a large mixing bowl. 
- Add honey and whole milk to the mixture and combine well. Sift all-purpose flour and baking powder together, and then add it to the egg mixture. 
- Further, mix well until all ingredients are well combined. Then rest the batter for at least 15 minutes to allow the gluten to relax. 
- While the batter is resting, take 2 tablespoons of sweet red bean paste. Then shape it into a round disk that will fit in the centre of each pancake. 
- Heat up the pan over low heat to 350ºF (175ºC) as high heat can cause uneven heating. Use a small piece of paper towel to apply a thin layer of vegetable oil to the pan. Wipe off the excess oil with a clean paper towel. 
- In addition, heat the pan first. Then pour the batter into a liquid measuring cup for easy pouring, and then fill the pan halfway with batter. Cook for 2 minutes, then add the red bean paste and set the timer for 3 minutes. After 1 minute, pour batter into the empty third of the pan and cook for the remaining 2 minutes. 
- Using a small metal spatula or skewer, pick up two pancakes with the filling. Then place them on top of the pancakes without filling. 
- Press down and cook for another 2 minutes. Loosen the edges of the pancakes and remove them from the pan. Lastly, cool the Imagawayaki on a wire rack, and repeat the process until all batter gets finished.
