These soft and chewy Lemon Sugar Cookies are made with fresh lemon zest and juice, rolled in sugar, and topped with a tangy lemon buttercream frosting. No chilling required - just 10 minutes of prep! Perfect for Spring, Summer, Easter, Mother's Day, baby showers, and summer parties.

Soft Lemon Sugar Cookies with Lemon Buttercream Frosting 

If you've been around here for a while, you already know I have a serious weakness for anything lemon. I've made lemon thumbprint cookies filled with lemon curd, lemon brownies with cream cheese frosting, a lemon raspberry bundt cake, and a lemon blueberry bundt cake - and I'm still not done.

These frosted lemon sugar cookies might just be my favorite of the bunch, because they deliver maximum lemon flavor with minimum effort: only 10 minutes of prep, no chilling the dough, no rolling pin, and no cookie cutters. Let me show you how easy this is!

Recipe Highlights

• Soft and chewy, never cakey. The secret is a tablespoon of cornstarch plus an extra egg yolk - I'll explain why below. These stay thick and tender for days.
• No chilling the dough! Unlike most sugar cookie recipes, you can scoop, roll, and bake these right away. From "I want cookies" to cookies in under an hour.
• Triple lemon flavor. Fresh lemon zest and lemon juice in the dough, plus more zest and juice in the buttercream. Every bite is bright and citrusy - I promise these are lemon cookies for true lemon lovers.
• That sparkly sugar coating. Rolling the dough balls in granulated sugar before baking gives the edges a delicate, crackly sweetness - just like my sugar-rolled lemon thumbprint cookies.
• Perfect for any occasion. Easter, Mother's Day, spring brunch, summer potlucks, cookie exchanges - these disappear fast wherever they go.

The Secret to Soft, Thick Lemon Cookies

Let me walk you through why this recipe works so well, because a couple of small ingredients make a big difference here.

Cornstarch is the tenderness trick. Adding just 1 tablespoon of cornstarch to the flour softens the dough's structure - cornstarch has no gluten, so it interrupts gluten development the same way cake flour does in my key lime bundt cake. The result is a cookie with a soft, almost melt-in-your-mouth center instead of a tough, bready one. Don't skip it!

The extra egg yolk adds richness and chew. One whole egg plus one extra yolk gives you the moisture and fat for a dense, chewy texture without making the cookies spread thin.

Ingredients You Need & Why

This recipe has 2 simple components: lemon sugar cookies and lemon buttercream. Below, I'll explain the key ingredients and why they're used. For the full ingredient list and detailed instructions, scroll down to the printable recipe card.

1) Lemon Sugar Cookie Ingredients:

• All-purpose flour: The base of the dough. I recommend spooning and leveling your flour (or better yet, weighing it) so you don't end up with too much, which can make cookies dry and cakey instead of soft.
• Cornstarch: This is my little trick for extra-tender cookies. It softens the gluten in the flour so the texture stays soft in the center.
• Baking powder: Gives these cookies their thick, slightly puffed shape.
• Kosher salt: Balances all that sweetness and makes the lemon flavor pop.
• Unsalted butter, room temperature: Make sure it's truly soft so it creams properly with the sugar. To check that, press a finger into it - it should leave an indent without sinking through.
• Granulated sugar: Creamed with the butter for that classic light, fluffy sugar cookie base.
• Lemon zest and lemon juice: Use fresh lemons here, not the bottled stuff. Freshly grated zest is where most of that bright lemon oil and flavor comes from.
• Egg + egg yolk: The extra yolk adds richness and helps keep the cookies soft and chewy instead of cakey.
• Vanilla extract and lemon extract: Vanilla rounds out the flavor, and the lemon extract is optional but I really do recommend it. It deepens the citrus flavor without adding more liquid to the dough.
• Granulated sugar, for rolling: This is what gives the cookies that pretty, sparkly, crackled top once they bake.

2) Lemon Buttercream Frosting Ingredients:

• Unsalted butter, room temperature: The creamy base of the frosting.
• Lemon zest: Beaten right into the butter first so the lemon oils really infuse the frosting.
• Powdered sugar: Added gradually for a smooth, lump-free frosting.
• Lemon juice: Also added gradually. This is what thins the frosting to the perfect spreadable consistency while adding even more tangy lemon flavor.

How to Make Lemon Sugar Cookies (Step-by-Step)

This is just a quick overview - you'll find the full printable recipe with exact measurements in the printable recipe card below.

• Prep. Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
• Whisk the dry ingredients. In a medium bowl, whisk together the flour, cornstarch, baking powder, and salt. Set aside.
• Cream the butter and sugar. In a large mixing bowl or stand mixer, beat the butter and sugar together until light and fluffy - about 2-3 minutes. Don't rush this step; it creates the little air pockets that keep the cookies soft.

• Add the lemon and eggs. Mix in the lemon zest, lemon juice, egg, egg yolk, vanilla extract, and lemon extract (if using) until fully combined, scraping down the sides of the bowl as needed. The dough will smell incredible already!
• Add the dry ingredients. Gradually mix the dry ingredients into the wet ingredients until just combined. Do not overmix - overmixing develops gluten and makes cookies tough, and we worked hard for that tender crumb.

• Scoop and roll. Scoop about 1.5 tablespoons of dough per cookie, roll into balls, then roll each ball in granulated sugar and place on the prepared baking sheet.

• Flatten slightly. Using a flat-bottomed glass or measuring cup, gently press down on each dough ball. You want them slightly flattened but still thick - they won't spread much in the oven, so this step shapes the final cookie.

• Bake. Bake for 9-10 minutes, until the edges are set and the centers still look slightly underbaked. Trust me on this - the centers finish setting on the hot baking sheet, and pulling them early is exactly what keeps these cookies soft and chewy. If they look fully done in the oven, they'll be dry once cooled.
• Cool. Let the cookies cool on the baking sheet for 10 minutes before moving them to a wire rack to cool completely.

How to Make the Lemon Buttercream Frosting

• Beat the butter and lemon zest until smooth. Gradually add the powdered sugar and lemon juice in stages, mixing until creamy and well combined.
• Adjust the consistency as needed with a little extra lemon juice or powdered sugar. 

• Frost the cookies only once they're completely cool. I know it's tempting to rush, but warm cookies will melt the buttercream and make it slide right off. Swirl it on with the back of a spoon or an offset spatula, top with a little extra lemon zest if you're feeling fancy, and enjoy!

Variations

• Skip the frosting for a simpler, less sweet lemon sugar cookie - they're delicious on their own with that crackly sugar coating. You could also drizzle them with a thin lemon glaze like the one on my raspberry lemon loaf.
• Make them lime or orange. Swap the lemon zest and juice for lime or orange - same method, whole new cookie. (If you love lime desserts as much as I do, my key lime bundt cake should be next on your list!)
• Add white chocolate chips. Fold in ¾ cup - lemon and white chocolate are a dreamy pair (that combination is exactly why my lemon brownies are so popular).
• Decorate for the holiday. Pastel sprinkles on the frosting make these adorable Easter cookies; yellow sanding sugar is perfect for summer.

My Top 6 Tips

• Room temperature butter matters. Cold butter won't cream properly, and melted butter makes the cookies spread. Take it out about an hour ahead.
• Zest first, juice second. It's nearly impossible to zest a juiced lemon half!
• Slightly underbake. I'll say it again because it's the single most important tip: the centers should look a touch underdone when you pull the pan from the oven. Watch the bake time closely. These cookies go from perfectly soft to overbaked quickly, so start checking at the 9-minute mark.
• Use the same scoop size for every cookie so they all bake evenly. A medium cookie scoop (1.5 tablespoons) is my go-to.
• Don't skip rolling the dough in sugar. This step creates that signature sparkly, slightly crackled cookie top that makes these look bakery-worthy.
• Let the cookies cool completely before frosting. I know it's tempting to frost them warm, but patience here pays off with a frosting that sets up nicely instead of sliding off.

FAQ (You Ask, I Answer)

1. Do I need to chill the dough? No! That's one of my favorite things about this recipe. The dough is sturdy enough to scoop and bake right away.
2. Can I use bottled lemon juice? You can, but I highly recommend fresh. And, since you need the zest anyway, you'll already have the lemons on hand.
3. Can I use salted butter instead of unsalted? Yes, just reduce the added salt in the recipe to ½ teaspoon.
4. Why did my cookies turn out dry? Almost always one of two things: too much flour (measure by weight or spoon-and-level) or overbaking. Remember, slightly underbaked centers are the goal. Be sure to take them out when the edges are set but the centers still look soft.  If they are showing any browning on them, they have baked way too long.  Make sure you are using a light-colored baking sheet too!
5. How many cookies does this make? About 26-28 cookies using a 1.5-tablespoon scoop.
6. Can I make these ahead? Yes! Bake the cookies up to 2 days ahead and store them unfrosted, then make the buttercream and frost the day you serve them.
