Hawaiian Butter Mochi Recipe

It’s January, which means it’s cold and grey. Who doesn’t need a little tropical inspiration? This classic Hawaiian butter mochi recipe will transport you to a sandy beach with gentle waves.

A Short History of Hawaiian Butter Mochi Recipe

The New York Times did a feature on this classic Hawaiian treat last year. The author interviewed a large number of mochi makers and eaters. However, they were unable to trace the origins of the butter mochi recipe.

In researching this blog post, we discovered a fascinating post by the KauKau Chronicles. The author notes that Hawaiian bakers also call butter mochi “bibingka.” He suggests that recipe may originally have come from Goa, rather than Japan. A Goan recipe known as bebinca is strikingly similar. It consists of layers of coconut-flavored cake made of eggs, coconut milk, and either coconut or wheat flour, and caramel. The recipe may then have traveled the trade routes connecting Portuguese colonies from Goa, to Malaysia, to Indonesia and the Philippines, and finally to Hawaii. As the cake traveled to the Philippines, it lost its layers, and gained the more gelatinous texture associated with sweet glutinous rice flour. Hawaiian bakers added butter to the recipe, giving it its rich and gently sweet flavor.

What’s this Mochi Stuff All About?

The primary ingredient in Hawaiian butter mochi is Mochiko. Mochiko is a very fine glutinous rice flour. It is made from mochigome which is glutinous short-grain Japanese rice. Despite its name, glutinous rice flour is naturally gluten-free, as is this recipe! In Japan, bakers traditionally use mochiko flour to make mochi. Do not replace the Mochiko flour with all purpose or some other kind of rice flour, as it will radically alter the chewy texture.

You can find Mochiko Flour in Asian grocery stores. We like either the Koda Farms brand, or the Bob’s Red Mill variety. If you can’t find any near you, it’s also easy to order online.
