4 large eggs
2 teaspoons vanilla extract
2 cups skim milk
One 1-pound box mochiko flour
2 cups sugar
2 teaspoons baking powder
1/2 teaspoon kosher salt
1/2 cup unsalted butter, melted
One 13 1/2-ounce can coconut milk
1/2 cup unsweetened shredded coconut
A few pinches offlaky salt (optional)
Preheat the oven to 350°F. Grease a 9 by 13-inch baking pan with butter or oil.
In a bowl, whisk together the eggs, vanilla, and milk. In another larger bowl, whisk together the mochiko, sugar, baking powder, and kosher salt. Pour the wet ingredients into the dry ingredients and, with a wooden spoon stir until well combined. Add the melted butter and coconut milk and mix until fully incorporated. Pour the mixture into the prepared pan and rap the pan on the counter a couple of times to bring any air bubbles up to the surface. Evenly sprinkle the shredded coconut on top of the mixture, a handful at a time, being careful not to jiggle the pan too much, as you want the coconut to stay on the top. Then sprinkle on a few pinches of flaky salt, if desired.
Bake until the mochi is set and golden brown on top, about 1 hour. Set the pan on a wire rack and let cool completely before slicing into rectangles using a plastic knife to minimize sticking; I cut four columns and five rows to make twenty 2 1/4 by 2 1/2-inchpieces. If the knife seems to be sticking, rub it with a little unsalted butter or neutral oil. Store in an airtight container at room temperature for up to 3 days.
