Preheat oven to 350°F. Lightly grease a 9x13 baking pan with cooking spray or butter.
Combine the dry ingredients in a large bowl.
Add the remaining ingredients to the dry mixture and mix well.
Pour into your prepared baking pan and bake for 1 hour.
Remove from the oven and let cool before cutting with a plastic knife. The baked mochi will resemble brownies.(plastic knives are key since the mochi won't stick to it)
