Butter a 9″ cast-iron skillet or baking dish. Set aside. Combine milk, cream, sugar, almond extract, vanilla, eggs, and salt in a blender. Blend for a few seconds to mix ingredients, then add the flour and blend until smooth, about 1 minute.
Pour the batter into the buttered skillet, then distribute cherries evenly on top. Sprinkle with the ground almonds. Bake until a skewer inserted into batter comes out clean and a golden brown crust has formed on top, approximately 30 minutes.
Dust with confectioners' sugar and serve. Can be served warm or at room temperature.
