Butter mochi is a classic Hawaiian dessert made from glutinous rice flour (mochiko). Adding matcha makes this rice cake a fun green color. Matcha butter mochi is a sweet, colorful, and dense rice cake that's perfect to share at parties.
Add in wet ingredients (coconut milk, evaporated milk, melted butter, eggs) and mix until well combined. Make sure to scrape down the sides of the bowl to check for any lumps of mochiko that did not get incorporated into the batter.
Pour into a greased 9x13" baking pan and sprinkle shredded coconut on top.
Bake for an hour, uncovered, or until the middle is set.
