For a decadent twist on traditional taiyaki, try making chocolate banana taiyaki. Here are the ingredients you'll need: - 1 cup all-purpose flour - 1/4 cup sugar - 1/2 teaspoon baking powder - 1/4 teaspoon salt - 1 egg - 3/4 cup milk - 1/4 cup cocoa powder - 1/2 cup chocolate chips - 1 ripe banana, sliced To make the batter, follow the same steps as the previous recipes, but this time, add cocoa powder to the dry ingredients before combining with the wet ingredients. Preheat the taiyaki pan or fish-shaped waffle iron and grease it with cooking spray or oil. Pour the batter into the molds, then place a few chocolate chips and a slice of banana in the center of each mold. Cover with more batter and cook for 2-3 minutes until golden brown. The combination of rich chocolate and sweet banana creates a heavenly flavor in this taiyaki variation. The melted chocolate chips add a gooey texture, making it a perfect indulgence for chocolate lovers.
