Preheat the oven to 350°F. Line baking sheets with parchment.
Cream the butter and sugar until fluffy. Beat in the eggs, vanilla, and almond extract.
Whisk the flour, baking powder, and salt; mix into the wet ingredients until a soft dough forms.
Scoop tablespoon balls of dough onto the sheets, 2 inches apart. Bake 10 to 12 minutes, until just set (do not brown).
Cool completely. Whisk the glaze ingredients until smooth; dip the top of each cookie in the glaze.
Shower with sprinkles immediately, before the glaze sets.
