What Ingredients You Will Need for the Lemon Lavender Shortbread Sandwich Cookies

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without fuss. Most are pantry staples, with the lavender adding a unique floral note that’s easy to substitute or omit if preferred.

• For the Shortbread Cookies:
• 2 cups (240g) all-purpose flour
• 1/2 cup (100g) granulated sugar
• 1 cup (227g) unsalted butter, softened (I like using Plugrá for its creaminess)
• 1 tablespoon dried culinary lavender (use sparingly for subtle flavor)
• 1/4 teaspoon fine sea salt
• 1 teaspoon pure vanilla extract
• For the Lemon Buttercream Filling:
• 1/2 cup (115g) unsalted butter, softened
• 1 1/2 cups (180g) powdered sugar, sifted
• 2 tablespoons fresh lemon juice (about 1 lemon)
• 1 teaspoon lemon zest (finely grated)
• 1/2 teaspoon vanilla extract
• Pinch of salt

If you want to switch things up, you can swap all-purpose flour with gluten-free 1:1 baking flour for a gluten-free option. For a dairy-free buttercream, Earth Balance vegan butter works well, though the flavor will be a bit different.

Pro tip: Look for dried lavender labeled “culinary” or “food grade” to avoid the overpowering fragrance of ornamental varieties. And if you find fresh lemons aren’t juicy enough, a splash of bottled lemon juice can help boost flavor without diluting the buttercream.

Equipment Needed

• Mixing bowls (medium and large)
• Electric hand mixer or stand mixer (for smooth buttercream)
• Measuring cups and spoons (accurate measurements are key)
• Baking sheets (preferably rimmed to catch any spread)
• Parchment paper or silicone baking mats (prevents sticking and easy cleanup)
• Fine mesh sieve (for sifting powdered sugar)
• Zester or microplane (for fresh lemon zest)
• Cooling rack (important for letting cookies cool evenly)

If you don’t have a stand mixer, an electric hand mixer works just fine for the buttercream, though whipping by hand is possible if you have patience. Using parchment paper instead of silicone mats is perfectly fine and budget-friendly.

Make sure your butter is softened but not melting—too warm and the dough will be sticky and hard to handle. This little detail makes a huge difference, trust me.

Preparation Method

1. Prepare the Cookie Dough (15 minutes): In a large bowl, cream the softened butter and granulated sugar together using an electric mixer until light and fluffy—about 3 to 4 minutes. The texture should resemble whipped cream, not greasy.
2. Add vanilla and lavender: Mix in the vanilla extract and dried culinary lavender, beating just until combined to avoid bruising the lavender leaves.
3. Combine dry ingredients: In a separate bowl, whisk the flour and salt together. Gradually add the flour mixture to the butter mixture, mixing on low speed until the dough just comes together. Don’t overmix—stop when you see no dry flour.
4. Chill the dough (30 minutes): Form the dough into a disk, wrap tightly in plastic wrap, and refrigerate. Chilling is crucial—it helps the cookies hold their shape and develop a tender texture.
5. Preheat oven and prepare pans (5 minutes): Heat your oven to 325°F (165°C). Line baking sheets with parchment paper or silicone mats.
6. Roll and cut cookies (15 minutes): On a lightly floured surface, roll chilled dough to about 1/4 inch (6 mm) thickness. Use a 2-inch (5 cm) round cookie cutter to cut shapes, gently transferring them to the baking sheet. Re-roll scraps once or twice.
7. Bake (15-18 minutes): Bake cookies until edges are set and just starting to turn golden—watch closely from 15 minutes onward. They’ll firm up more as they cool.
8. Cool completely: Let cookies cool on the baking sheet for 5 minutes, then move to a wire rack to cool fully. No filling until cookies are cool or buttercream will melt.
9. Make the lemon buttercream (10 minutes): Beat softened butter with an electric mixer until creamy. Gradually add sifted powdered sugar, mixing on low. Add lemon juice, zest, vanilla, and salt. Beat on medium-high until smooth and fluffy—about 3 minutes. Adjust powdered sugar or lemon juice if needed for consistency.
10. Assemble the cookies: Spread or pipe about 1 tablespoon (15 ml) of buttercream onto the flat side of one cookie, then sandwich with another. Gently press to spread filling evenly to edges.
11. Chill (optional): For best texture, chill assembled cookies for 30 minutes before serving. This helps the buttercream set and flavors meld.

Quick tip: If dough feels sticky while rolling, pop it back in the fridge for 10 minutes. Also, watch your baking time closely—overbaking dries them out, which is a common shortbread pitfall I’ve learned the hard way.

Cooking Tips & Techniques

Shortbread can be tricky, but these tips make a big difference:

• Don’t skip chilling: Chilling the dough prevents spreading and keeps cookies tender. I learned this after a batch spread into sad pancake shapes!
• Use room temperature butter: It creams better with sugar and traps air for a lighter cookie. Too cold, and the dough won’t mix well; too soft, and cookies get greasy.
• Measure flour correctly: Spoon and level your flour rather than scooping directly—too much flour makes dry cookies.
• Watch the baking time: Shortbread is done when edges are lightly golden. They firm up as they cool, so don’t wait for deep browning.
• Get the buttercream right: Use fresh lemon juice and zest for brightness. If too thin, add more powdered sugar; if too thick, a splash of lemon juice or milk thins it.
• Pipe the filling: Using a piping bag or zip-top bag with the corner snipped gives neat, even filling—much prettier than spooning.

Multitasking tip: While cookies bake, whip up the buttercream to save time. I usually prep my kitchen and ingredients first, then let the oven do the rest while I clean up.

Variations & Adaptations

Want to switch things up? Here are some ideas:

• Herbal Twist: Swap lavender for dried rosemary or thyme for a savory-sweet combo that pairs well with lemon.
• Chocolate Dipped: Dip half of each finished sandwich cookie in melted dark chocolate for a decadent finish.
• Berry Filling: Mix a tablespoon of raspberry or blueberry jam into the buttercream for fruity bursts.
• Gluten-Free: Use a 1:1 gluten-free flour blend instead of all-purpose flour. The texture will be slightly different but still delicious.
• Vegan Option: Replace butter with vegan butter alternatives in both dough and buttercream, and use powdered sugar labeled vegan.

Personally, I once tried adding a teaspoon of dried rose petals to the dough for a floral medley. It was a bit much for some, but I loved the romantic vibe it brought. Feel free to experiment—this recipe handles delicate flavor tweaks well.

Serving & Storage Suggestions

These cookies are best served at room temperature, allowing the buttercream to be soft and luscious. They pair beautifully with a cup of hot tea, like chamomile or Earl Grey, which complements the lavender notes.

For gatherings, arrange them on a pretty platter with fresh lemon slices and sprigs of lavender for a charming presentation. If you want a refreshing beverage, a light sparkling lemonade balances the richness perfectly.

To store, keep cookies in an airtight container at room temperature for up to 3 days. For longer keeping, refrigerate up to one week or freeze assembled cookies wrapped tightly in plastic wrap and stored in a freezer-safe container for up to 3 months.

Reheat frozen cookies by thawing at room temperature and chilling briefly before serving. Flavors mellow and meld beautifully overnight, making these cookies even better the next day.
