Brown Sugar Shortbread Cookies with Vanilla Glaze

Bake brown sugar shortbread cookies with vanilla glaze for tender, buttery treats. Step-by-step instructions make dessert easy.

Brown Sugar Shortbread Cookies with Vanilla Glaze are tender, buttery biscuits prepared from a simple dough of unsalted butter, light or dark brown sugar, all-purpose flour, and a touch of salt, then baked until lightly golden and finished with a smooth icing made from confectioners’ sugar, milk, and vanilla extract. The brown sugar imparts a gentle caramel flavor and softer crumb than traditional white-sugar shortbread, while the vanilla glaze adds sweetness and a polished finish. These cookies are commonly served during winter holidays, at afternoon tea, or as an everyday accompaniment to coffee or milk, and they travel well for gifting or bake-sale tables.

Notes

Chef’s Note: For deeper flavor, brown half the butter, chill it until firm, then cream it with the remaining butter before adding the sugar; the toasted milk solids amplify the cookie’s caramel notes. Roll to ¼ in / 6 mm for a crisper snap, or closer to ⅜ in / 1 cm for a more tender bite. Brush the glaze on while the cookies are still slightly warm so it fuses into a smooth, fast-setting finish.

Frequently Asked Questions

Can I prepare the dough (or bake the cookies) in advance and freeze them for later use?
Yes. Shape the dough into a disk (or cut it into un-baked cookies), wrap airtight, and freeze for up to 2 months; thaw in the refrigerator, then slice/roll and bake as directed—add 1–2 extra minutes if baking from partially frozen. Fully baked, un-glazed cookies also freeze well for 6–8 weeks; thaw at room temperature, then apply the vanilla glaze once they’ve warmed and dried.
Can I substitute gluten-free flour for all-purpose flour without noticeably altering the cookies’ texture or spread?
Yes—use a 1:1 (cup-for-cup) gluten-free baking blend that already contains xanthan or guar gum and you’ll get nearly the same thickness and butter-rich crumb, though the cookies may be a shade more tender and spread a little less. Chill the cutouts well before baking and check doneness 1-2 minutes sooner, as gluten-free flours often brown faster.
Q3: Can I swap in dark brown sugar for light brown sugar, and how will that change the flavor or texture?
Yes—dark brown sugar can replace light brown sugar in equal measure with no adjustments to the recipe. The extra molasses will deepen the caramel-toffee flavor and give the cookies a slightly darker hue, while the added moisture may make the crumb a touch softer but not enough to affect shaping or bake time.
