• 1/4 teaspoon salt
• 1/2 cup (1 stick) unsalted butter, softened
• 1 cup granulated sugar
• 1 large egg
• 1 teaspoon vanilla extract
• Zest of 1 lemon
• 1/2 cup (1 stick) unsalted butter, softened
• 2 cups powdered sugar
• 1 tablespoon culinary lavender, finely ground
• 2 tablespoons heavy cream
• 1 teaspoon vanilla extract
• A few drops of purple food coloring (optional)

How to Make Them

1. Preheat the oven to 350°F (175°C) and line two baking sheets with parchment paper.
2. Whisk together 2 cups all-purpose flour, 1/2 teaspoon baking powder, and 1/4 teaspoon salt in a medium bowl; set aside.
3. Beat 1/2 cup softened unsalted butter and 1 cup granulated sugar in a large bowl until light and fluffy, about 2–3 minutes.
4. Mix in 1 large egg, 1 teaspoon vanilla extract, and the zest of 1 lemon.
5. Gradually add the dry ingredients to the wet mixture, stirring just until combined; avoid overmixing.
6. Roll the dough on a floured surface to about 1/4-inch thickness and use a round cookie cutter to cut out cookies; place them on the prepared sheets with space between.
7. Bake the cookies for 8–10 minutes, or until the edges just start to turn golden brown.

8. Remove the cookies from the oven and cool completely on a wire rack.
9. Finely grind 1 tablespoon culinary lavender using a spice grinder, mortar and pestle, or a sharp knife.
10. Beat 1/2 cup softened unsalted butter until creamy for the buttercream.
11. Add 2 cups powdered sugar slowly to the butter, mixing well after each addition.
12. Fold in the finely ground lavender, 2 tablespoons heavy cream, and 1 teaspoon vanilla extract; add a few drops of purple food coloring if desired.
13. Beat the buttercream until fluffy and smooth, about 2–3 minutes.
14. Spread or pipe the buttercream onto the flat side of half the cooled cookies and sandwich with the remaining cookies.
15. Pipe a small swirl of buttercream on top of each sandwich and garnish with a thin lemon slice and a small sprig of fresh lavender, if desired.

Pro Tips for Best Results

• Culinary lavender is the best choice for baking since it’s safe to eat and has a mild flavor. Avoid regular lavender, which can taste bitter and harsh.
• Getting the perfect texture: Don’t overbake—cookies should be firm but still soft in the center. Aim for golden edges without deep browning.
• Use of food coloring: This is optional but adds a lovely pastel lavender shade to your buttercream that looks as good as it tastes.

These lemon lavender sandwich cookies are just perfect for afternoon tea or as a light, elegant dessert after dinner. For a classic tea-time spread, serve them alongside a slice of Sour Cream Pound Cake. They also shine at bridal showers or garden parties when their delicate flavors can really stand out—consider adding Lemon Blueberry Delight to keep the citrus theme going. My favorite pairing? A steaming cup of Earl Grey tea or a chilled glass of sparkling lemonade to complement that bright, floral flavor combo.

Variations and Flavor Swaps

• Want stronger lemon punch? Mix 1 to 2 teaspoons fresh lemon juice into your buttercream for an extra bright lemon-lavender contrast.
• For a crumbly twist, swap the cookie dough with classic shortbread made of 3 parts flour, 2 parts butter, and 1 part sugar.
• Try a little fruity surprise by spreading a thin layer of blueberry jam or lemon curd beneath the buttercream before sandwiching. For more ways to play with the lemon-blueberry combo, try Lemon Blueberry Fluff.
• If dried lavender isn’t your thing, try 1/2 teaspoon culinary lavender extract instead—but be careful, as extracts can be stronger and you may want to adjust the amount.
• Skip the purple food coloring if you prefer, and adorn your cookies with sugared lemon peel or crystallized lavender petals instead of fresh sprigs for a crunchy garnish.

Storing and Freezing Tips

If you plan to enjoy your lemon lavender sandwich cookies soon, store them in an airtight container in the fridge for up to 5 to 7 days. Take them out about 15 to 30 minutes before eating, so the buttercream softens up for the best taste.

If your kitchen is cool (under 70°F/21°C), these cookies can sit out at room temperature for a day or two in an airtight container without any trouble.

Want to freeze them? Freeze the baked cookies (before filling) in a single layer until solid, then transfer to a freezer bag for up to three months. When ready, thaw completely and fill with buttercream. You can also freeze fully assembled cookies for up to a month—wrap each one individually and thaw in the fridge before serving.

Frequently Asked Questions

• Do I have to use culinary lavender? Yes! Culinary lavender is milder and made for eating. Regular ornamental lavender tends to be bitter and can overpower your buttercream.
• How do I grind the lavender? You can use a spice grinder, mortar and pestle, or finely chop dried lavender buds with a sharp knife. Aim to get it very fine so it blends smoothly into your buttercream.
• How can I avoid a bitter lavender taste? Use only culinary lavender, measure carefully (this recipe uses 1 tablespoon), and grind it finely. Avoid steeping lavender buds directly in hot liquids, which can make the flavor too strong.
• Can I make these ahead of time? Absolutely! Bake your cookies a day or two in advance and whip up the buttercream the same day you’ll assemble them. You can even put the sandwiches together up to a day before and keep them refrigerated.
• What if I don’t have heavy cream? You can substitute whole milk in a pinch, though the buttercream might be a little less rich. Add it slowly, a teaspoon at a time, until you reach the texture you want.
• Why aren’t my cookies soft? It’s usually due to baking too long. Take them out when the edges just start to turn golden, and remember to roll the dough about 1/4-inch thick—that’ll help keep them tender and soft.
