What is Hawaiian Custard Butter Mochi?

So if you’ve never heard of Hawaiian custard butter mochi, first of all, I’m sorry. Secondly, you are in for such a treat that I am actually physically excited for you! As I mentioned before, Hawaiian custard butter mochi is a dessert made from glutinous rice flour, sugar, butter, and eggs. The dough is usually molded into little cubes and then steamed. The final product is a soft, chewy dessert with a creamy custard center and a crispy outer crust.

Excuse me for a moment while I wipe the drool from my keyboard.

History of Hawaiian Custard Butter Mochi This

This decadent dessert was originally brought to Hawaii by Japanese plantation workers arriving from Okinawa. It quickly became a staple dessert for families and special occasions alike. The secret to a great mochi lies in the steaming process, which can be difficult! If you under-steam your mochi, you will end up with something closer to pudding than anything else.

Ok, Ok…just give me the darn recipe!
