Preheat oven to 350°F (175°C). Generously butter a 9-inch round baking dish.
Spread the pitted cherries evenly across the bottom of the prepared dish.
In a blender (or bowl), combine eggs, milk, granulated sugar, flour, salt, vanilla, and almond extract. Blend or whisk until smooth.
Pour the batter gently over the cherries.
Bake for 35–40 minutes, until puffed and golden brown on the edges and just set in the center.
Let cool slightly. Dust with powdered sugar before serving.
Serve warm, room temperature, or chilled.
