This recipe for Ube Brochi (Brownie Mochi) yields a delicious, slightly sweet and chewy mochi brownie. It features real ube (purple yam) and glutinous rice flour, and is based on my popular Matcha Brochi recipe.
In a large bowl, whisk together the grated ube, egg, sugar, milk, vanilla extract, and sea salt until smooth.
Add in the mochiko (or glutinous rice flour) and whisk until incorporated.
Pour the batter into the prepared baking pan.
Give it a few taps to release any trapped bubbles.
Bake at 350°F/177°C for about 40 minutes, or until a toothpick inserted comes out clean. (To prevent excessive browning, cover with aluminum foil about 10 minutes into the bake).
Let cool in the pan for 5 minutes before transferring to a wire rack to completely cool.
