Preheat oven to 350°F (175°C). Grease a 12-cup muffin tin well (but do not use liners).
Prepare topping: Spoon about 1½ teaspoons melted butter into each muffin well. Sprinkle evenly with brown sugar, then arrange cherry halves cut-side down. Add a tiny drop of almond extract to each well.
Mix dry ingredients: Whisk flour, baking powder, and salt.
Cream butter & sugar until light and fluffy (2–3 minutes).
Add eggs, one at a time, then mix in almond and vanilla extracts.
Alternate flour and milk, beginning and ending with flour, mixing just until combined.
Spoon batter gently over cherries, filling each cup about ¾ full.
Bake 22–25 minutes, until lightly golden and a toothpick comes out clean.
Cool 5 minutes only, then run a knife around edges and invert onto a parchment-lined tray.
