Thick, tender drop-style sugar cookie with vanilla-bean flecks, a whisper of almond, and a royal-icing drizzle that dries hard for stacking.
Ingredients
Cookies
Royal Icing Drizzle
Cream: Beat butter and sugar on medium-high until light and fluffy (3–4 min).
Wet: Add egg, vanilla bean paste, and almond extract. Beat smooth.
Dry: Whisk flour, cornstarch, baking powder, cardamom (optional) and salt. Add on low just until a cohesive dough forms — don't overmix.
Chill: Shape into a disc, wrap, chill 30 min.
Bake: 350°F (175°C). Scoop balls (2 oz, or 1.5 oz for the bar), roll smooth, flatten into thick pucks. Bake 12–14 min for 2 oz / 10–12 min for 1.5 oz — set and pale, not browned. (If tops start coloring before the center sets, drop to 325°F and add a few minutes; low-and-slow sets a thick pale cookie through without tanning it.) Cool completely.
Drizzle: Whisk icing to a "5-second" consistency (a drawn line fades into the surface in ~5 sec). Pipe a tight zig-zag.
