Iced Lemon Lavender Shortbread Cookies

My grandmother kept a small ceramic jar of dried lavender on her windowsill, tucked behind her basil and rosemary. I thought it was purely decorative until one Sunday afternoon she crumbled some into a batch of shortbread dough, explaining that the English have been baking with lavender for centuries. The scent that filled her kitchen was unlike anything I'd experienced, floral yet somehow comforting, like a garden in butter form.

Last spring I made these for my book club, and everyone immediately fell quiet when they took their first bite. Someone actually asked if I'd bought them from a fancy bakery, which I took as the highest compliment. Now they request them every time we meet, and I've learned to double the recipe because they disappear faster than you'd think something so delicate could.

Ingredients

• Unsalted butter: Bring this to room temperature naturally, never in the microwave, so it creams properly with the sugar
• Powdered sugar: The cornstarch in powdered sugar helps create that signature shortbread texture that's tender rather than crisp
• Lemon zest: Use a microplane if you have one, and really only take the bright yellow part, avoiding the bitter white pith beneath
• Culinary dried lavender: Please buy lavender specifically marked as culinary grade, as ornamental lavender may have been treated with pesticides
• Salt: This small amount is crucial to balance the floral notes and prevent the cookies from tasting cloyingly sweet
• All purpose flour: Spoon this into your measuring cup and level it off rather than scooping directly, which can pack it down
• Fresh lemon juice: Room temperature lemon juice incorporates more smoothly into the icing for that perfect glossy finish
• Extra lavender buds: These are optional for garnish, but they make the cookies look absolutely stunning on a platter

Instructions

Cream the butter and sugar:

Beat the softened butter and powdered sugar together for about 3 minutes until the mixture looks pale and fluffy, scraping down the bowl once midway through

Add the flavorings:

Mix in the lemon zest, finely chopped lavender, and salt until everything is evenly distributed throughout the butter mixture

Incorporate the flour:

Add the flour gradually and mix on low speed just until the dough comes together and no dry streaks remain, being careful not to overwork it

Shape and chill:

Divide the dough in half and form each piece into a 2 inch diameter log, wrapping them tightly in plastic wrap and refrigerating for at least 30 minutes until firm

Preheat and prep:

Heat your oven to 350°F and line two baking sheets with parchment paper while you wait for the dough to chill

Slice the cookies:

Cut the chilled dough logs into 1/4 inch rounds and arrange them on the prepared baking sheets, leaving about an inch of space between each cookie

Bake to perfection:

Bake for 14 to 16 minutes until the edges are just barely turning golden, then let them cool on the baking sheets for 5 minutes before transferring to a wire rack

Make the icing:

Whisk together the sifted powdered sugar, lemon juice, and lemon zest until completely smooth, adding more juice drop by drop if needed to reach a drizzling consistency

Finish and serve:

Drizzle or spread the lemon icing over the completely cooled cookies and optionally sprinkle with a few lavender buds before letting the icing set completely

Save

My neighbor smelled these baking through our shared kitchen wall and actually knocked on my door to ask what I was making. I ended up sending her home with a small plate, and now we have a standing tea date every other Thursday specifically for these cookies and whatever book we're both reading.

Making These Ahead

The dough logs freeze beautifully for up to three months, so I often make a double batch and keep one package tucked away in the freezer. Just let them thaw in the refrigerator overnight before slicing and baking. The unbaked slices can also be frozen flat on a parchment lined tray, then transferred to a freezer bag for easy single serving baking whenever the mood strikes.

Pairing Suggestions

These cookies absolutely sing alongside a cup of Earl Grey tea, where the bergamot notes complement the lavender beautifully. I've also served them with chamomile tea for a completely caffeine free afternoon treat that feels incredibly luxurious. For something different, try them with a glass of prosecco or a light white wine like pinot grigio.

Gift Giving Tips

I've found these make the most thoughtful hostess gift, especially when wrapped in parchment and tied with twine and a small sprig of fresh lavender. For holiday giving, I stack them in clear cellophane bags and add a handwritten tag with brewing suggestions. Once I gave a batch to my daughter's teacher, and she said they were the best thing she'd received all year.

• Package the cookies between layers of parchment paper to protect that delicate icing
• Include a small note about the lavender being culinary grade in case recipients are curious
• These ship reasonably well if packed in a tin with plenty of cushioning, though the icing might crack slightly

Save

There's something deeply satisfying about serving something that looks so elegant but came from such humble ingredients. I hope these bring a little moment of calm and beauty to your kitchen, just as they have to mine.

Recipe FAQ

→ Can I use fresh lavender instead of dried?

Fresh lavender contains more moisture and can make the dough soggy. Stick with culinary dried lavender buds, finely chopped, for the best texture and flavor distribution.

→ How long do these cookies stay fresh?

Store in an airtight container at room temperature for up to 5 days. The icing may soften slightly over time but the shortbread remains tender and flavorful.

→ Can I freeze the dough?

Yes, wrap the dough logs tightly in plastic wrap and freeze for up to 3 months. Thaw in the refrigerator overnight before slicing and baking.

→ What type of lavender should I use?

Use only culinary-grade lavender (English or Provence varieties). Regular ornamental lavender may have been treated with pesticides and lacks the refined flavor needed for baking.

→ Can I make these without the icing?

Absolutely. The plain shortbread is delicious on its own, with the lemon zest and lavender providing plenty of flavor. Bake for the same time and enjoy as simple buttery cookies.

→ Why does my dough crumble when slicing?

The dough needs to be thoroughly chilled—30 minutes minimum, but longer is better. If it's still crumbly, let it warm slightly for 5-10 minutes before slicing.
