Ooh, I have lots of favourites *o*
First is Kakigōri, especially matcha flavour. I like how it's really cold and refreshing, and the syrup is just heaveeeeeen xD
Fudge flavoured cone ice-cream because it reminds me of going to the shop at school with my friends (just a month ago, haha) and I always got that particular ice-cream once it started getting warm.
I like making fruit smoothies, using seasonal fruits like strawberries, cherries, blueberries. Strawberry and banana with a bit of mint is the best combination

Watermelon and pineapple are also amazing, especially watermelon but pineapple is also really nice.
Other things... slushies, even though I rarely drink them, big ice-cream parfaits, green tea latte, iced coffee....
I just realised this post is getting long-winded so I'll finish here ^^
