Taiyaki is a fish shaped cake with a sweet bean inside! Now, the chestnut flavor is the latest fad among people! Because it contains seasonal ingredients! I ate it a few days ago. It was delicious! Sayuri take note of the changes made. Your pronunciation is clear but when you use exclamation marks ( !) the intonation needs to change to illustrate emphasis. I moved your exclamation mark to the end to show that it was delicious! We need to emphasise this part and not the former part. Shout out if you need assistance on intonation and punctuation. Otherwise I could hear your words clearly, well done.
