Preheat the oven to 350°F (175°C).
Butter a 9-inch pie plate or baking dish.
Spread the frozen cherries evenly in the dish.
Whisk or blend together the eggs, milk, flour, sugar, vanilla, almond extract, salt, and melted butter until smooth.
Pour the batter over the cherries.
Bake for 45–55 minutes, until puffed, golden, and set in the center.
Let cool for 15–20 minutes before serving.
