Set your oven to 350°F and adjust a rack to sit in the center. Use butter or oil to generously coat a 9x13-inch pan. Melt the butter and leave it aside for later.

In a medium bowl, whisk together vanilla, eggs, and milk until it’s smooth and fully mixed.

Pour the wet mixture into the dry mix. Using a wooden spoon, stir it all up until combined. Add the melted butter and coconut milk, and keep mixing until it's completely smooth.

Empty the smooth batter into your greased pan. Lightly drop the pan on the counter a few times to pop any bubbles hiding inside.

Evenly scatter the shredded coconut on top in small portions. If you want, throw on a pinch of flaky salt to finish.

Bake in the oven until the center is firm and the surface is golden, about 60-70 minutes.

Move the pan to a cooling rack and leave it there for an hour. Once it's cooled fully, cut it into 20 rectangle pieces with a plastic knife. Grease the knife with butter if the mochi sticks.
