Matcha Sugar Cookies with Lavender

The moment I opened that tin of culinary-grade matcha my sister brought back from Kyoto, I knew these cookies had to happen. It was a rainy Sunday afternoon and something about that vibrant green powder against the gray sky felt like magic waiting to happen.

I first made these for my book club meeting and watched everyone is eyes widen at that first bite. There is something about the combination that makes people slow down and really savor each bite instead of just mindlessly snacking.

Ingredients

• 2 cups all-purpose flour: The foundation that gives these cookies their structure while keeping them tender
• 1 tablespoon culinary-grade matcha powder: Use the good stuff here because lower grades can taste bitter or grassy
• 1/2 teaspoon baking powder: Just enough lift to give these cookies their delicate texture
• 1/4 teaspoon sea salt: Enhances all the flavors and balances the sweetness
• 3/4 cup unsalted butter: Room temperature is crucial here for proper creaming with the sugar
• 1 cup granulated sugar: Creates that crisp edge while keeping centers soft
• 1 large egg: Binds everything together and adds richness
• 1 teaspoon pure vanilla extract: Rounds out the matcha flavor beautifully
• 1/2 cup unsalted butter for frosting: Again temperature matters for that silky smooth buttercream
• 2 cups powdered sugar: Sifting first prevents any lumpy frosting disasters
• 2 tablespoons milk: Adjust this to get your perfect frosting consistency
• 1 teaspoon culinary lavender buds: Must be culinary grade because regular lavender can have pesticides
• 1/2 teaspoon pure vanilla extract: A little extra vanilla never hurts anything
• Pinch of salt: Keeps the frosting from becoming cloyingly sweet

Instructions

Prep your baking space:

Preheat oven to 350 degrees and line two baking sheets with parchment paper so you are ready to go

Whisk the dry ingredients:

In a medium bowl combine flour matcha baking powder and salt until everything is evenly distributed

Cream butter and sugar:

Beat butter and sugar for 2 to 3 minutes until the mixture looks pale and fluffy like a cloud

Add the egg and vanilla:

Mix until just combined being careful not to overbeat at this stage

Combine wet and dry:

Gradually add the dry ingredients on low speed mixing only until you no longer see flour streaks

Shape the cookies:

Roll tablespoon portions into balls place on baking sheets and gently flatten with your palm

Bake to perfection:

Bake 10 to 12 minutes until edges are set but centers still look slightly soft

Cool completely:

Let them rest on the baking sheets for 3 minutes then move to a wire rack to cool all the way through

Make the lavender frosting:

Beat butter until creamy then gradually add powdered sugar followed by milk ground lavender vanilla and salt

Frost and finish:

Once cookies are completely cool spread with frosting and garnish with a pinch of lavender buds

These became my go-to recipe for when I want to make something that feels special without spending all day in the kitchen. Something about the green cookies with purple frosting just makes people smile.

Getting The Right Matcha Flavor

I learned the hard way that not all matcha is created equal. That cheap stuff from the regular baking aisle gave my first batch this weird bitter aftertaste that nobody could quite place.

Frosting Like A Pro

The secret to bakery-perfect frosting is letting those cookies cool completely. I once got impatient and the frosting melted right into the warm cookies creating this weird soupy mess.

Serving Suggestions

These pair incredibly well with a cup of green tea or even some champagne if you are feeling fancy. The flavors somehow enhance each other in this beautiful way.

• Stack them on a pretty cake stand for maximum visual impact
• Serve within a day or two because they soften over time
• Keep them in the fridge if you make them ahead for a party

Every time I make these I am transported back to that rainy afternoon with that tin of Kyoto matcha. Sometimes the best recipes find you when you least expect them to.

Recipe FAQs

→ What does matcha taste like in cookies?

Matcha adds earthy, grassy notes with a subtle bitterness that balances the sweetness of the cookie dough. The flavor is similar to green tea but more concentrated and complex, creating a sophisticated taste profile that pairs beautifully with creamy vanilla and floral lavender.

→ Can I taste the lavender in the frosting?

Yes, but it's subtle and fragrant rather than overpowering. One teaspoon of finely ground culinary lavender provides a delicate floral aroma and flavor that complements the matcha without tasting soapy or artificial. The key is using culinary-grade lavender and grinding it finely to distribute evenly.

→ Why are my cookies flat or spreading too much?

This usually happens if the butter is too soft or the dough isn't chilled. Make sure your butter is at room temperature (not melted) and consider chilling the scooped dough for 15-20 minutes before baking. Also, ensure you're measuring flour correctly by spooning it into the measuring cup rather than dipping.

→ Can I make these cookies ahead of time?

Absolutely. You can prepare the dough up to 3 days in advance and store it wrapped in the refrigerator, or freeze it for up to 3 months. The baked cookies (without frosting) keep well in an airtight container for 4-5 days. Frost them the day you plan to serve for the freshest taste and texture.

→ Is it safe to use lavender in food?

Yes, as long as you use culinary-grade lavender specifically grown for consumption. Garden center lavender may contain pesticides or chemicals. Culinary lavender buds are safe to eat and provide that characteristic floral aroma and flavor. Start with the recommended amount—you can always add more, but it's difficult to remove once incorporated.

→ Can I make these vegan?

Yes, substitute the butter with plant-based butter or coconut oil, and use a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) or commercial egg replacer. The texture will be slightly different but still delicious. Ensure your powdered sugar is vegan-certified, as some brands process sugar with bone char.
