Lilac Shortbread Cookies Ingredients

Discover the perfect blend of flavors for these delightful floral treats.

For the Cookies

Butter (1 and 1/2 cups, cubed) – Adds richness and creates a tender texture; unsalted butter is best for controlling sweetness.
Lilac Florets (2 cups, firmly packed) – Infuses the dough with a delicate floral flavor; make sure to remove any green parts to avoid bitterness.
Cake Flour (~2 and 1/2 cups) – Provides a light and tender crumb; if unavailable, all-purpose flour is a suitable substitute, but the cookies may be denser.
Powdered Sugar (1/3 cup & ~1/2 cup for glaze) – Contributes to the cookie’s sweetness and melt-in-your-mouth texture; adjust according to your taste preferences.
Corn Starch (3 tbsp) – Enhances tenderness and softness; can be swapped with more flour if necessary.
Salt (a small pinch) – Balances sweetness and enhances the overall flavor profile.

For the Glaze (optional)

Lilac Syrup (1-2 tbsp for glaze) – Adds moisture and extra sweetness, beautifully complementing the floral notes; optional if you prefer a less sweet finish.

How to Make Lilac Shortbread Cookies

Infuse the Butter: Begin by simmering the cubed butter with the lilac florets in a small saucepan over low heat for about 5-10 minutes. This allows the flavors to meld beautifully. Remove from heat and let it cool before refrigerating to solidify.
Prepare Cookie Dough: In a mixing bowl, combine the chilled, infused butter with the cake flour, powdered sugar, corn starch, and a pinch of salt. Mix until a smooth dough forms, with a buttery aroma filling your kitchen.
Chill the Dough: Wrap the dough in plastic wrap and refrigerate for 30 minutes. Chilling makes it easier to handle when shaping your cookies and enhances their texture.
Shape and Bake: Preheat your oven to 350°F (175°C). Roll the chilled dough into small balls and place them on a baking sheet lined with parchment paper. Flatten them slightly and bake for about 12-15 minutes, or until the edges are just golden.
Glaze (optional): While the cookies cool, prepare the glaze by mixing the remaining powdered sugar with lilac syrup until smooth. Drizzle it over the cooled cookies for an extra touch of sweetness.

Optional: Dust with a sprinkle of lavender sugar for a stunning finish.

Expert Tips for Lilac Shortbread Cookies

Infusion Time Matters: Allow the butter to infuse with lilac florets for at least 5-10 minutes; longer infusion enhances the floral flavor.

Chill for Success: Don’t skip the chilling step; it firms up the dough, making it easier to shape and preventing spreading in the oven.

Watch the Bake: Keep an eye on your cookies! They should be just golden around the edges for that perfect melt-in-your-mouth texture of lilac shortbread cookies.

Glaze Wisely: If using the glaze, apply it after the cookies have cooled completely to prevent it from melting into the cookies.

Keep It Simple: For a floral touch without complications, simply serve these cookies with tea or coffee for a delightful pairing.

How to Store and Freeze Lilac Shortbread Cookies

Room Temperature: Store cookies in an airtight container for up to 1 week; this preserves the delicate flavor and texture.

Fridge: If you prefer an extended freshness, keep them in the fridge for up to 2 weeks. Place them in a sealed container to prevent them from absorbing moisture.

Freezer: For longer storage, freeze the cookies in a single layer on a baking sheet, then transfer them to an airtight container or freezer bag for up to 1 month.

Reheating: To enjoy warm lilac shortbread cookies, gently reheat in the oven at 300°F (150°C) for about 5-7 minutes, maintaining their delightful texture.

Lilac Shortbread Cookies Recipe FAQs

What type of lilacs should I use for these cookies?
Absolutely! Use fresh lilac florets from non-toxic varieties. Ensure they are fully bloomed and fragrant, avoiding any green parts or wilted flowers, as they can impart bitterness to your cookies.

How should I store the cookies after baking?
Store your lilac shortbread cookies in an airtight container at room temperature for up to 1 week. Make sure the container is completely sealed to keep them fresh and to prevent them from drying out.

Can I freeze lilac shortbread cookies?
Yes! For longer shelf life, freeze these cookies by placing them in a single layer on a baking sheet until firm, then transfer to an airtight container or freezer bag. They can be stored for up to 1 month. When you’re ready to enjoy, simply thaw at room temperature or reheat gently in the oven.

What if my cookies are too crumbly?
If you find your cookies are too crumbly, it might be due to too much flour or not enough moisture. Try adding small amounts of additional melted butter or even a dash of cream to the dough to restore moisture and help bind the ingredients better.

Are these cookies safe for pets?
While lilacs are typically non-toxic to dogs, avoid sharing these cookies with pets due to the high butter and sugar content. Always prioritize your pet’s dietary needs and consult with your veterinarian if in doubt.

What can I do if I don’t have cake flour?
No worries! You can substitute with all-purpose flour, but keep in mind that the texture may be a bit denser. For a lighter result, consider replacing a portion of the all-purpose flour with cornstarch (1 cup all-purpose flour minus 2 tablespoons + 2 tablespoons cornstarch for each cup needed). This will mimic the tenderness of cake flour.
