Preheat the oven to 350°F (177°C), and line an 8-inch square baking pan with parchment paper and set aside. (if double the recipe, you can use a 13*9-inch baking pan.)
Beat the eggs, and then add vanilla and milk. Mix well.
In a large bowl, combine all the dry ingredients: mochiko, sugar, and baking powder.
Add the dry ingredients to the egg and milk mixture. Mix well.
Add melted butter and coconut cream. Mix until the batter is completely smooth with no lumps.
Pour the batter into the baking pan. Use a spatula to smooth the surface.
Bake for 1 hour or until the cake turns golden brown.
Remove from the oven and allow the mochi cake to cool to room temperature. Then use the parchment to lift the cake out of the pan.
Use a sharp knife to cut into squares.
