These New Year’s sugar cookies are soft, buttery, and topped with a generous crunch of sparkling sugar, making them just the thing for a festive midnight snack or a holiday party tray.

The dough comes together in one bowl, chills while you get other things ready, and bakes up into cookies that hold their shape beautifully. You’ll have cookies on the cooling rack within a couple of hours, with no fussy piping or royal icing required.

What Makes These Cookies So Good

These aren’t the sugar cookies that puff up and lose their shape. The dough has just the right ratio of butter to flour and a touch of cornstarch, so the edges stay crisp and the centers stay tender.

Sparkling sugar gives them a festive crackle and a bright pop of sweetness that feels celebratory without a lot of extra work. I’ve made them for New Year’s Eve gatherings, and they disappear faster than the champagne.

Ingredients

2 1/4 cups all-purpose flour: spooned and leveled, not scooped
2 tablespoons cornstarch: gives the cookies a soft center
1 teaspoon baking powder: helps the cookies rise just enough
1/2 teaspoon fine sea salt: balances the sweetness
1 cup unsalted butter, softened: unsalted lets you control the salt level
1 cup granulated sugar: cream it well with the butter for a smooth dough
1 large egg, at room temperature: helps everything emulsify
2 teaspoons vanilla extract: use the real stuff for the best flavor
Sparkling sugar (white, gold, or silver): for decorating after baking

Variations / Substitutions

Almond or citrus flavor: swap the vanilla for 1 teaspoon almond extract or 2 teaspoons finely grated lemon or orange zest.
Cut-out shapes: any sharp cookie cutter works; stars, numbers, champagne bottles, or clocks feel especially festive for New Year’s.
Gluten-free: use a 1:1 gluten-free flour blend that contains xanthan gum, and skip the cornstarch.
Sparkling sugar color: white is classic, but gold and silver catch the light and really say “celebration.”

How to Make Sparkly New Year’s Sugar Cookies

Step 1: Mix the Cookie Dough

Preheat the oven to 350°F (175°C). In a medium bowl, whisk together the 2 1/4 cups flour, 2 tablespoons cornstarch, 1 teaspoon baking powder, and 1/2 teaspoon salt. In a large bowl, beat the 1 cup softened butter and 1 cup granulated sugar with an electric mixer on medium speed until light and fluffy, about 2 minutes. Beat in the 1 egg and 2 teaspoons vanilla extract until just combined. Gradually mix the dry ingredients into the wet ingredients on low speed until no streaks of flour remain, scraping the bowl as needed.

The dough will be soft but not sticky. Shape it into a disc, wrap tightly in plastic, and chill for at least 1 hour, until firm. This rest helps the cookies hold their shape later.

Step 2: Roll and Cut the Cookies

On a lightly floured surface, roll out the chilled dough to about 1/4 inch thick. Use New Year’s-themed cutters to cut shapes, rerolling scraps as needed. Place cookies 1 inch apart on parchment-lined baking sheets.

If the dough gets too soft to handle, pop the cutouts back into the fridge for 5 minutes. Cold dough going into the oven is the secret to crisp edges and a defined shape.

Step 3: Bake the Cookies

Bake one sheet at a time on the middle rack for 9 to 11 minutes, until the edges are just barely golden and the tops are set but pale. Rotate the pan halfway through baking for even browning.

The cookies will look underdone in the center, and that’s exactly right. They’ll continue to set as they cool on the baking sheet. Let them cool on the sheet for 5 minutes, then transfer to a wire rack to cool completely.

Step 4: Finish with Sparkling Sugar

While the cookies are still slightly warm, brush each one lightly with a little corn syrup or honey mixed with a drop of water. Immediately sprinkle with sparkling sugar in the color you like, pressing gently so it sticks. Let the cookies cool completely so the sugar sets.

Work one cookie at a time so the glaze doesn’t dry before you add the sugar. The sugar will catch the light and give that New Year’s Eve sparkle.

Tips for Perfect Cut-Outs

If your kitchen is warm, pop the cut cookies on the baking sheet into the freezer for 5 minutes before baking.
For the cleanest edges, dip the cookie cutter in flour between each cut.
Sparkling sugar won’t melt in the oven, so add it after baking for the brightest shimmer.
Don’t skip the cornstarch, it’s the small addition that keeps the cookies soft for days.

Bake times by cookie thickness:

Thickness	Bake Time
1/8 inch	7 to 9 mins
1/4 inch	9 to 11 mins
1/2 inch	11 to 13 mins

Keeping the Cookies Fresh

Refrigerate: Store cookies in an airtight container at room temperature for up to 5 days. They stay soft and tender that whole time. Freeze: Freeze baked, undecorated cookies for up to 3 months. Thaw at room temperature and add the sparkling sugar just before serving.

Frequently Asked Questions

Can I make the dough ahead of time?

Yes. Wrap it tightly and refrigerate for up to 2 days, or freeze for up to 1 month (thaw overnight in the fridge before rolling).

Why did my sugar cookies spread?

The dough was likely too warm when it went into the oven. Chill the cutouts for at least 10 minutes on the baking sheet before baking to prevent spreading.

Can I use cookie icing instead of sparkling sugar?

Sure. Let the cookies cool completely, then flood them with a simple powdered sugar icing and top with sprinkles or leave them plain.

How do I make gold sparkling sugar stick without corn syrup?

A light brush of beaten egg white or a mixture of equal parts vanilla extract and water works too.
