Mini Egg NYC Cookies – Gooey 35-Minute Treat

Hi friends, it's Maya! If you've ever stood in line at a bakery for one of those giant, crackly-topped NYC cookies, this one's for you. These Mini Egg NYC Cookies are my Easter-season obsession, and they come out thick, gooey in the middle, and absolutely packed with pastel chocolate crunch.

The magic is in two things: cold butter and a quick chill. Cold butter keeps the cookies tall instead of spreading into pancakes, and the chill lets the flavors settle so you get that bakery-style crackle on top. You don't need a stand mixer, just a bowl, a spoon, and a little patience.

I made these for my niece's spring bake sale last year and they sold out before the lemon bars even got unwrapped. Now they're a yearly tradition in our house, and I have a feeling they'll become one in yours too.

About the Ingredients

1 cup (225g) cold unsalted butter, cubed

Cold butter is the secret to tall, thick cookies, so don't let it soften on the counter. If you only have salted butter, cut the added salt in the recipe to 1/4 teaspoon.

1 1/4 cups (250g) light brown sugar, packed

Brown sugar keeps these cookies chewy and adds a soft caramel note. Dark brown sugar works too if you want a deeper molasses flavor.

1/2 cup (100g) granulated sugar

White sugar helps the edges crisp up and the tops crackle. Don't swap it all for brown sugar or the cookies spread too much.

2 large eggs, room temperature

Room-temperature eggs blend smoothly into the cold butter mixture. If you forgot to take them out, sit them in warm water for 5 minutes.

2 teaspoons vanilla extract

Real vanilla extract makes a noticeable difference here. Vanilla bean paste is a lovely splurge if you have it.

3 1/4 cups (406g) all-purpose flour

Spoon the flour into your cup and level it off, or you'll pack in too much and get dry cookies. A kitchen scale is the safest bet.

1 tablespoon cornstarch

Cornstarch is my quiet trick for a soft, tender crumb. If you're out, swap in an equal amount of cake flour.

1 teaspoon baking soda

Check the date on your baking soda, since old baking soda won't give you the lift these thick cookies need. Baking powder is not a good substitute here.

1/2 teaspoon fine sea salt

Salt balances all that sugar and makes the chocolate taste richer. Kosher salt works, just use a slightly heaped half teaspoon.

1 1/2 cups (255g) Mini Eggs, lightly crushed

Crush them in a zip-top bag with a rolling pin so you get big shards and fine dust. Cadbury Mini Eggs are classic, but any candy-coated chocolate egg works.

1 cup (170g) semi-sweet chocolate chunks

Chunks melt into gooey pools better than chips. Chopped chocolate bars or dark chocolate chunks are great swaps.

Tips & Tricks

Keep the Butter Cold

Warm butter makes flat cookies, so cube it straight from the fridge and work quickly with your fingertips until you have a shaggy, pebbly dough.

Chill Before Baking

A 30-minute fridge rest (or overnight) firms the dough and deepens the flavor. Skipping it is the number one reason these spread too thin.

Don't Overbake

Pull them when the edges are set but the centers still look a little underdone. They finish setting on the hot pan.

Press Extra Mini Eggs On Top

Save a handful of crushed pieces to press onto the dough balls right before baking so the tops look as good as they taste.

Step-by-Step Instructions

1. Whisk Dry Ingredients

Whisk the flour, cornstarch, baking soda, and salt together in a medium bowl and set it aside. This keeps the leaveners evenly distributed so every cookie rises the same way.

2. Rub Butter Into Sugars

In a large bowl, rub the cold butter cubes into the brown sugar and granulated sugar with your fingertips until no butter lumps bigger than a pea remain. It'll look sandy, and that's exactly right.

3. Beat In Eggs and Vanilla

Beat in the eggs one at a time, then the vanilla, until the mixture looks glossy and slightly thickened, about 1 minute. It may look a little curdled at first, but it comes together.

4. Fold In Dry Mix and Mix-Ins

Fold in the dry ingredients with a spatula until just a few flour streaks remain, then fold in the crushed Mini Eggs and chocolate chunks. Stop mixing the moment the flour disappears so the cookies stay tender.

5. Chill the Dough

Cover the bowl and chill it in the refrigerator for at least 30 minutes, or up to 24 hours. Cold dough holds its shape and gives you that thick, gooey center.

6. Scoop and Chill Again

Scoop the dough into 6 large balls, about 1/3 cup each, and place them on a parchment-lined tray. Chill for another 15 minutes while the oven heats.

7. Bake at 350F (175C)

Heat the oven to 350F (175C). Bake the dough balls on a parchment-lined sheet for 14 to 16 minutes, until the edges are golden brown and set but the centers still look soft and slightly glossy. If you have a thermometer, the centers should read about 175F (79C).

8. Cool and Finish

Let the cookies rest on the hot pan for 10 minutes, then move them to a wire rack. Sprinkle with flaky salt while warm if you like, and enjoy them gooey.

Delicious Variations

Brown Butter Blondie Style

Brown the butter first, cool it until solid again, then proceed for a nutty, toffee-like twist.

Double Chocolate

Swap 1/2 cup of the flour for cocoa powder and use white chocolate chunks with the Mini Eggs.

Mini Version

Scoop 1-tablespoon balls and bake at 350F (175C) for 8 to 10 minutes for poppable cookie bites.
