Flat lay of a small mound of all-purpose flour, a teaspoon of baking soda, a tablespoon of cornstarch, a pinch of salt, a half cup of unsalted butter softened and creamy, a half cup of light brown sugar packed, a small pile of granulated sugar, one whole uncracked brown egg, one whole uncracked egg yolk, a small white ceramic bowl with vanilla extract, a small white ceramic bowl filled with semi-sweet chocolate chips, a small white ceramic bowl with toffee bits, a small white ceramic bowl of crushed potato chips, a small white ceramic bowl of chopped pretzels, and a small white ceramic bowl containing long holiday jimmies, all arranged in perfect symmetry on a clean white marble surface, soft natural light, photo taken with an iPhone, professional food photography style, fresh ingredients, white ceramic bowls, no bottles, no duplicates, no utensils, no packaging --ar 2:3 --v 7 --p m7354615311229779997

All-purpose flour: The sturdy base for perfect structure without being too dense.
Baking soda: Helps the cookies spread just right with a tender crumb.
Cornstarch: A little secret ingredient for softness and a delicate bite.
Salt: Enhances all the flavors and balances the sweetness perfectly.
Unsalted butter: Room temperature butter is crucial — not too soft or melted — to avoid cookie spread.
Light brown and granulated sugar: Brown sugar adds moisture and chewiness, while granulated sugar keeps the edges crisp.
Egg and egg yolk: Provide richness and help bind everything together.
Vanilla extract: Brings out all those cozy cookie flavors.
Chocolate chips: Semi-sweet is classic, but white chocolate or chopped chocolate work wonders too.
Toffee bits or red & green M&Ms: Adds sweetness with a bit of crunch.
Potato chips: Surprising but genius — they contribute a crunchy, salty dimension.
Chopped pretzels: More saltiness and crisp texture to keep things interesting.
Holiday jimmies: These sprinkles hold their shape in the oven and provide festive color without melting away.

Make It Your Way

I love this recipe because it’s a playground for kitchen creativity. Over the years, I’ve tweaked my mix-ins to suit different moods and occasions, and you should too — it’s fun to make it truly your own.

Variation: For a holiday spin, swap the toffee bits for crushed peppermint and use red and green M&Ms. It’s festive and refreshing.
Diet-Friendly: Try swapping potato chips for gluten-free chips and choose dairy-free chocolate chips for a friendlier option.
Nutty Addition: I sometimes add chopped walnuts or pecans for extra crunch and flavor complexity.

Step-by-Step: How I Make Kitchen Sink Cookies Recipe

The image shows several soft, round cookies with a light golden brown color. Each cookie is topped with layers of different textures: small crunchy pretzel sticks, square caramel pieces, chocolate chips, and red and green sprinkles scattered on top. Some potato chip pieces are also layered on the cookies, adding a rough texture contrast. The cookies are close together on a white marbled surface, showing a mix of smooth and crunchy toppings. The colors mainly include light brown, dark brown, red, green, and beige. photo taken with an iphone --ar 2:3 --v 7

Step 1: Whisk Your Dry Ingredients Together

Start by whisking the flour, baking soda, cornstarch, and salt in a medium bowl. This ensures everything’s evenly distributed so your cookies bake evenly and have the perfect texture. Take your time here—I like to whisk for a solid 2 minutes.

Step 2: Cream Butter and Sugars Until Fluffy

In a large bowl, using your mixer—handheld or stand—beat the butter, brown sugar, and granulated sugar for about 2-3 minutes. You want a light, creamy mixture. This is where the magic begins; well-creamed butter and sugar make your cookies tender but with crispy edges.

Step 3: Add Eggs and Vanilla for Richness

Beat in the egg, egg yolk, and vanilla extract until the mixture is light and fluffy. This extra yolk helps keep the cookies chewy while adding richness. Don’t forget to scrape the bowl sides down to incorporate everything.

Step 4: Slowly Add Dry Ingredients

Set your mixer to low speed and gradually add the dry ingredients, mixing just until combined. Overmixing can make the cookies dense, so pause as soon as the flour disappears.

Step 5: Fold in All the Fun Mix-Ins

Use a rubber spatula to gently fold in your chocolate chips, sprinkles, toffee bits, crushed potato chips, and chopped pretzels. I like to save some mix-ins to press on top of the cookies after scooping—adds an eye-catching finish!

Step 6: Shape and Bake

Scoop the dough with a large cookie scoop or a scant ¼ cup measure onto parchment-lined sheets. Roll them gently into tall ovals rather than perfect balls to get thicker, chewier cookies. Bake at 350°F for 10-12 minutes, until the edges are golden and the tops look set but not dry.

Step 7: The Sweet Finishing Touch

Right out of the oven, use the rim of a glass to gently swirl around each cookie’s edge — this trick gives you those perfectly round, bakery-style cookies. Then press a few extra mix-ins on top. Let them cool on the pan for 5 minutes, then transfer to a wire rack to finish cooling completely.

Top Tip

Over the years, I’ve learned a few things that help my Kitchen Sink Cookies Recipe turn out perfect every time. These simple tips have saved me from wasted batches and disappointing results — I hope they help you as much as they helped me!

Butter Temperature Matters: Use room temperature butter that feels cool to the touch (around 69°F). Too soft or melted butter makes the cookies spread too thin.
Don’t Overmix the Dough: When adding dry ingredients, mix only until combined to avoid tough cookies.
Press Extra Mix-ins on Top: Doing this right after baking gives the cookies a beautiful, rustic look and adds texture to every bite.
Use Holiday Jimmies: These sprinkles don’t melt or bleed in the oven like other sprinkles, so your cookies stay colorful and festive.

How to Serve Kitchen Sink Cookies Recipe

Kitchen Sink Cookies - Serving Suggestion

Garnishes

I don’t often garnish these cookies because they’re already packed with so much goodness. But when I do, a light dusting of powdered sugar or a drizzle of melted chocolate adds a fancy touch for gift-giving or parties.

Side Dishes

Pair these cookies with a tall glass of cold milk or a warm cup of coffee or tea. They’re a perfect sweet and salty snack to enjoy with your favorite drink.

Creative Ways to Present

I’ve arranged these cookies on festive platters with some holiday greens for Christmas parties, and for birthdays, I serve them in mason jars tied with ribbons. They make simple yet memorable gifts or party favors.

Make Ahead and Storage

Storing Leftovers

Store your baked Kitchen Sink Cookies in an airtight container at room temperature, and they’ll stay soft and delicious for up to 5 days. I usually line the container with parchment paper to keep them from sticking.

Freezing

I highly recommend freezing the dough balls for this recipe. Just scoop and freeze them on a tray, then transfer to a freezer bag. They keep well for up to 3 months. When you’re ready, bake them straight from frozen—add 1-2 minutes to the baking time.

Reheating

If you have leftover cookies, pop them in a 300°F oven for about 5 minutes or zap them in the microwave for 10-15 seconds. This brings back that fresh-baked warmth and chewy texture.

Frequently Asked Questions:

Can I use salted butter in this recipe?

While you can use salted butter, I recommend unsalted to better control the saltiness, especially since this recipe includes salty mix-ins like pretzels and potato chips.

Why do the cookies need cornstarch?

Cornstarch helps create a softer, more tender texture by preventing the cookies from being too dense or tough. It’s a simple ingredient that elevates the bite.

Can I substitute the mix-ins with other snacks?

Absolutely! This recipe is very flexible—you can swap mix-ins for your favorites, like nuts, dried fruit, or other candies. Just keep in mind how they may affect texture and baking time.

What’s the best way to shape the cookies?

I find rolling the dough into tall ovals rather than balls helps achieve thicker, chewier cookies. Plus, using a glass rim to gently swirl the edges right after baking gives that professional, round look.

Final Thoughts

This Kitchen Sink Cookies Recipe has been my go-to whenever I want a cookie that treats every craving at once. It’s joyful, a little nostalgic, and incredibly satisfying. Trust me, once you try it, you’ll find yourself keeping these on repeat — just like I do! So grab your mixing bowl, throw in your favorite mix-ins, and make these your next kitchen adventure.
