These Banana Mochi are so easy to make because you can cut the bananas into the perfect mochi size. I am using some bruised bananas that I have been ripening for over a week. I was going to save them for banana bread but I got a fat craving for mochi so here we are.
In a medium microwave-safe bowl, combine the glutinous rice flour and sugar. Whisk in the water until smooth. Cover the bowl with a wet paper towel or a large plate. Microwave the mochi mixture for 1 minute, then remove it from the microwave and stir with a wet spatula. Repeat this process two more times until the mochi is thick and translucent. Let the mochi cool for 5-10 minutes.
Dust your work surface with a generous amount of cornstarch. Place the mochi on the surface and dust it with cornstarch. Cut the mochi into eight pieces. Optional: You can transfer the mochi pieces to a parchment-lined baking sheet and freeze for 20 minutes. This will make shaping them much easier.
Flatten one portion between your palms and use a pastry brush to dust off excess cornstarch. Place a piece of banana in the center. Pull the sides of the mochi over the banana and pinch to seal. Dust a small amount of cornstarch on the outside and use a pastry brush to remove excess. Place the banana mochi seam-side down and repeat with the remaining mochi.
