我以前存过一个类似的。区别在加半块butter, 蛋，还有牛奶。不过很像

给你参考一下。也许你可以改进出自己的recipe. 声明我没做过。

Original recipe makes 1 - 9x13 inch pan Change Servings

1 pound mochiko (glutinous rice flour)

2 1/2 cups white sugar

1 teaspoon baking powder

1/2 cup butter, melted

3 cups whole milk

5 eggs

1 teaspoon vanilla extract

1 cup sweetened, flaked coconut

Preheat the oven to 350 degrees F (175 degrees C). Grease a 9x13 inch
baking dish.
In a medium bowl, whisk together the eggs, vanilla and milk. In a
separate larger bowl, stir together the rice flour, sugar, and baking
powder. Pour the wet ingredients into the dry ingredients, and stir to
blend. Mix in melted butter and coconut. Pour into the prepared pan.
Bake for 1 hour in the preheated oven. Cool completely, then cut into
squares to serve.
