Combine dry ingredients (glutinous rice flour, matcha, sugar, and salt) in the bowl of a stand mixer, or a large mixing bowl, and stir together.
Add wet ingredients (vegetable oil, milk, and eggs) to dry ingredients.
Set a running timer, stir all ingredients on low speed for 1 – 2 minutes. Stop the mixer and scrape the edges and bottom of the bowl with a spatula; increase speed to medium and continue mixing. Repeat (mix and scrape) for 12 minutes total, or until the batter is velvety smooth.
Let the finished batter rest in the bowl for 30 minutes, uncovered at room temperature, before baking. In the meantime, preheat the oven according to the pan you would like to use (listed below).
Tap pans on the counter to remove air bubbles in the batter; which will result in a smoother texture in the finished cake.
Bake until the crust is slightly golden; baking time may vary depending on type of pan, oven, and flavor ingredients (see “Notes” section for more on this).
Check the cake 2 – 4 minutes before the set-time, by inserting a toothpick into the center of the cake. If the toothpick is clean, then the cake is done. If the batter sticks to the toothpick, bake for an additional 2 – 5 minutes.
Let mochi cake cool for 15 – 20 minutes before removing from the pan. Then place the cake on a cooling rack to continue to cool for another 20 minutes before cutting. The mochi loaves can be cut into any size and shape to your preference. I like to cut them into cubes.
