Matcha Sugar Cookies With Lavender Frosting

The first time I baked with matcha, I accidentally breathed in a cloud of the bright green powder and spent the next ten minutes trying to convince my roommate I hadn't joined a fairy cult. But those cookies turned out so beautiful—this stunning jade color that seemed almost too pretty to eat—that I've been experimenting with matcha baking ever since. Adding lavender frosting felt like a natural extension, something about the earthiness of matcha begging for flowers.

I made these for my sister's bridal shower last spring, and I swear, three different people asked me for the recipe before they'd even finished their first cookie. There's something about the combination—this slightly grassy, almost bitter note from the matcha playing against this sweet, perfumed frosting—that makes people pause and really pay attention to what they're eating.

Ingredients

• 2 cups all-purpose flour: The foundation that lets the matcha shine without competing flavors
• 1 tablespoon culinary-grade matcha powder: Splurge on ceremonial grade here because cheap matcha tastes disappointingly bitter and dull
• 1/2 teaspoon baking powder: Just enough lift to keep these tender without turning them into cakes
• 1/4 teaspoon sea salt: A tiny pinch that makes the floral notes sing
• 3/4 cup unsalted butter: Room temperature is non-negotiable—cold butter creates weird texture glitches
• 1 cup granulated sugar: Cream this thoroughly with the butter or your cookies will spread into sad, thin pancakes
• 1 large egg: Bring it to room temperature so it incorporates evenly into the dough
• 1 teaspoon pure vanilla extract: Don't use imitation—the fake stuff clashes weirdly with the lavender
• 1/2 cup unsalted butter for frosting: Again, room temp, or you'll end up with lumpy, stubborn buttercream
• 2 cups powdered sugar, sifted: Sifting seems tedious but prevents those frustrating tiny lumps that never disappear
• 2 tablespoons milk: Whole milk creates the silkiest frosting texture
• 1 teaspoon culinary lavender buds, finely ground: Grind these right before using or they lose their fragrant punch
• 1/2 teaspoon pure vanilla extract: Reinforces the vanilla in the cookies for cohesion
• Pinch of salt: Balances the extreme sweetness of buttercream
• Purple gel food coloring: Optional but creates that dreamy lavender hue that matches the flavor

Instructions

Get your oven ready:

Preheat to 350°F and line two baking sheets with parchment paper—silicone mats work too but I've found parchment gives slightly better browning on the bottoms.

Whisk the dry team:

In a medium bowl, combine flour, matcha, baking powder, and salt until the matcha is evenly distributed—you want no green streaks in your final dough.

Cream butter and sugar:

Beat butter and sugar for a full 2 to 3 minutes until the mixture looks pale and fluffy, properly aerated for tender cookies.

Add egg and vanilla:

Mix until everything's incorporated, but don't overbeat or you'll develop too much gluten and your cookies will be tough.

Combine it all:

Gradually add dry ingredients on low speed, stopping as soon as the flour disappears—overmixing is the enemy of delicate sugar cookies.

Shape and space:

Roll tablespoon portions into balls and place them 2 inches apart on your prepared sheets, then flatten slightly with your palm.

Bake to perfection:

Slide them into the oven for 10 to 12 minutes, pulling them out when edges look set but centers still feel soft to the touch.

Cool completely:

Let them rest on the baking sheets for 3 minutes before moving to a wire rack—warm cookies will melt your frosting right off.

Make the lavender frosting:

Beat butter until creamy, gradually add powdered sugar, then mix in milk, ground lavender, vanilla, and salt until fluffy and dreamy.

Frost and finish:

Once cookies are completely cool, spread with buttercream and sprinkle with a pinch of whole lavender buds for that extra touch of elegance.

My neighbor texts me every spring asking when I'm making these again. She had one at a block party three years ago and still talks about it, which feels like the highest compliment something so simple can receive.

Getting The Matcha Right

I've learned through expensive mistakes that not all matcha is created equal. The bright green culinary-grade powder from Japanese markets makes all the difference between cookies that taste vibrantly herbal and ones that just taste vaguely grassy and bitter.

Lavender Balance

Ground lavender is potent stuff—I once accidentally doubled the amount and ended up with frosting that tasted exactly like expensive hand soap. Now I always start with less and add more gradually, tasting as I go.

Frosting Like A Pro

Wait until cookies are completely cool before frosting, or you'll watch all your beautiful buttercream slide right off the edges. I usually bake in the evening and frost the next morning when everything has reached room temperature.

• Chill frosted cookies for 15 minutes to set the frosting if you're stacking them
• A small offset spatula gives you those swirled bakery-style peaks
• Store unfrosted cookies in an airtight container for up to 3 days before frosting

Pin It

There's something meditative about the process, watching the bright green dough transform under the oven's heat, the whole kitchen smelling like a fancy spa. These have become my go-to when I need to bake something that feels special without spending all day in the kitchen.

Recipe FAQs

→ What does matcha taste like in baked goods?

Matcha adds an earthy, slightly grassy flavor with subtle bitterness that balances sweetness. In these cookies, it provides a sophisticated depth while creating a beautiful natural green color.

→ Can I use dried lavender buds instead of ground?

Ground lavender is essential for the frosting texture. Whole buds would be gritty. Grind culinary-grade lavender in a clean spice grinder or mortar and pestle until fine before incorporating.

→ How do I know when the cookies are done baking?

The edges should be set and slightly firm while the centers remain soft. They'll continue cooking on the hot baking sheet during the 3-minute cooling period. Underbaking slightly ensures a tender texture.

→ Can I make the dough ahead of time?

Yes, the dough can be refrigerated for up to 48 hours. Let it come to room temperature for 15-20 minutes before scooping and baking. You can also freeze scooped dough balls for up to 3 months.

→ Why is my frosting too thick or thin?

Adjust consistency by adding more milk (1 teaspoon at a time) to thin, or more powdered sugar (1 tablespoon at a time) to thicken. Room temperature ingredients are crucial for proper emulsification.

→ What type of matcha works best for baking?

Use culinary-grade matcha rather than ceremonial grade. Culinary matcha has a stronger flavor that holds up during baking and is more cost-effective for larger quantities. Look for vibrant green color.
