Preheat the oven to 375F and line a muffin tin.

Whisk the flour, sugar, and baking powder together.

Combine the milk, melted butter, eggs, and almond extract in another bowl.

Fold the wet into the dry until just combined, then gently fold in the diced peaches.

Divide among the cups and sprinkle the tops with sliced almonds.

Bake 20 to 22 minutes until golden, then cool slightly.
