Method

1. Make the Batter: In a bowl, whisk together the flour, baking powder, baking soda, and sugar.
   
   
2. Combine Wet Ingredients: In a separate bowl, whisk together the egg, milk, oil, and vanilla extract.
   
   
3. Combine Wet and Dry: Gradually add the wet ingredients to the dry ingredients, whisking constantly until a smooth batter forms. Let the batter rest for 30 minutes at room temperature.
   
   
4. Heat the Taiyaki Pan: Heat a taiyaki pan over medium heat. Lightly grease the molds with oil.
   
   
5. Fill the Molds: Pour batter into each mold, filling about 2/3 full. Spoon a small amount of red bean paste into the center of each batter half.
   
   
6. Cook the Taiyaki: Close the pan and cook for 2-3 minutes, or until golden brown. Carefully open the pan and flip the taiyaki. Cook for another 2-3 minutes, or until golden brown and cooked through.
   
   
7. Serve: Remove the taiyaki from the pan and let them cool slightly before serving.
   
   

Tips:

• You can find taiyaki pans online or at some specialty kitchen stores.
  
  
• You can use other fillings, such as custard cream, chocolate, or even savoury fillings like cheese or vegetables.
  
  
• For best results, use a light and airy batter.
