Crisp Lemon Shortbread Cookies with Zesty Glaze

These lemon shortbread cookies with lemon glaze deliver bright, refreshing citrus in every bite. Buttery, delicate and melt-in-your-mouth, this recipe produces shortbread that holds its shape—perfect for cutout cookies. A simple lemon glaze and a sprinkle of zest add an extra layer of flavor.

This lemon shortbread is adapted from a classic cutout shortbread base. The dough is easy to work with and resists spreading, so it stays crisp around the edges and tender in the center. The recipe combines pantry staples with lemon oil for an extra concentrated citrus note; the dough and the glaze both get brightness from lemon oil, fresh lemon zest and lemon juice.

The dough mixes quickly and can be rolled right away. Chill the cut cookies briefly—10 minutes in the freezer or 30 minutes in the refrigerator—so the butter firms up and the cookies keep their shape during baking. The result is small buttery cookies with a lively lemon profile.

Ingredients

• Unsalted butter — Use room temperature butter for easy creaming. Cut into small cubes to speed softening if needed.
• Powdered sugar — Gives sweetness without graininess for a smooth shortbread texture.
• Lemon oil — A concentrated lemon flavoring that boosts citrus intensity. If you don’t have it, a high-quality lemon extract can be used, though lemon oil is more potent.
• Lemon zest — Freshly grated zest adds aroma, flavor and a touch of color. Reserve the zested lemon to squeeze for the glaze.
• Corn starch — Keeps the cookies tender by reducing gluten development for a melt-in-your-mouth crumb.

Instructions

Follow these steps to make glazed lemon shortbread cookies. Full details and ingredient amounts are in the recipe card.

Add the corn starch and mix on low until incorporated, then add the flour and mix just until the dough pulls together. Turn the dough onto a rectangle of parchment, top with another piece of parchment and roll to about 1/4 inch (6 mm) thickness.

Remove the top parchment and cut cookies with your favorite cutter. Place cutouts about 1 inch (2.5 cm) apart on a parchment-lined sheet. Chill cutouts in the freezer for 10 minutes (or refrigerate 30 minutes) to firm the butter. Bake at 300°F (150°C) for 22–24 minutes until set and very pale golden at the edges. Allow cookies to cool on the sheet before glazing.

To make the glaze, whisk powdered sugar and fresh lemon juice together in a small bowl until smooth, taking care not to whip air into it. Dip the top of each cooled cookie into the glaze, letting excess drip off. Arrange glazed cookies on parchment and sprinkle with lemon zest while the glaze is still wet. Once the glaze sets, cookies can be stacked for storage.

Hint: Chill cut cookies before baking: 10 minutes in the freezer or 30 minutes in the refrigerator. Cold butter helps the cookies hold their shape and prevents spreading.

Substitutions

Cornstarch: If you prefer not to use cornstarch, replace it with an equal amount of all-purpose flour.

Unsalted butter: Salted butter may be used—reduce added kosher salt to 1/4 teaspoon. Butter brands vary in salt content, so adjust to taste.

Variations

Try these flavor twists to change up the cookies:

• Lemon lavender — Sprinkle culinary-grade lavender on the glaze while it’s still wet for a floral note.
• Lemon poppyseed — Stir 1 tablespoon of poppy seeds into the dough with the zest and sprinkle a few on top of the glaze.
• Citrus shortbread — Swap lemon zest, oil and juice for equal amounts of orange, lime or grapefruit for a different citrus character.
• Lemon thyme — Fold 1 tablespoon of fresh thyme leaves into the dough with the zest and garnish glazed cookies with a few thyme leaves (use fresh thyme only).
• Sugared, not glazed — If you prefer to skip the glaze, sprinkle the tops with sanding sugar before baking for sparkle.

Equipment

Cookie cutter — Any shape works; a fluted round cutter is used here for small cookies.

Baking pans — Half-sheet pans work well for even baking and spacing.

Microplane grater — Ideal for zesting citrus finely and evenly.

Lemon oil — Optional but recommended for a concentrated lemon boost if you have it on hand.

Storage

Store: Keep cookies in an airtight container at room temperature for up to one week. Once the glaze is firm, cookies can be stacked in layers.

Freeze: Freeze cookies in a sealed container or freezer bag for up to 3 months.

Make ahead: The dough can be made up to 48 hours ahead and refrigerated tightly wrapped. Bring dough to room temperature before rolling, then chill cutouts as directed prior to baking. Prepare the glaze just before dipping—the glaze forms a skin if left to sit.
