All-purpose flour: The foundation that gives the cookies their structure without being too heavy.
Baking soda: Helps the cookies rise just enough for a light, tender crumb.
Cornstarch: Adds softness and a delicate texture, making each cookie pillowy.
Salt: Balances the sweetness and enhances all the flavors.
Unsalted butter: Room temperature is key here—soft but cool butter gives the best creaming and prevents spreading.
Light brown sugar: Brings moisture and a hint of caramel flavor that deepens the cookie’s taste.
Granulated sugar: Adds crispness and balances the softness from the brown sugar.
Egg & egg yolk: The egg binds everything together, while the extra yolk adds richness and chew.
Vanilla extract: The classic flavor enhancer that ties all the ingredients in harmony.
Semi-sweet chocolate chips: Classic mix-in for melty pockets of chocolate—feel free to experiment with your favorites.
Toffee bits or M&Ms: Adds sweetness and a crunchy surprise that’s fun to bite into.
Crushed potato chips: The salty crunch gives that wonderful contrast to sweetness and softness.
Chopped pretzels: More salt and crunch—trust me, it’s addicting.
Holiday jimmies (sprinkles): These keep their shape and color after baking—perfect for festive flair without the mess.

Colorful fun: Swap holiday jimmies for rainbow sprinkles when you want a cheerful everyday version.
Mix-ins galore: Consider toasted nuts, dried cranberries, or even mini marshmallows to keep each batch feeling fresh and exciting.

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

The image shows several thick, round cookies with a light golden-brown color as the base layer. Each cookie is topped with broken pretzel sticks, dark chocolate chips, small toffee chunks, and thin, crinkled potato chip pieces. Bright red and green sprinkles are scattered across the top, adding color contrast and a festive touch. The cookies rest on a white marbled surface with some crumbs and sprinkles around them, creating a close, cozy feel. Photo taken with an iphone --ar 2:3 --v 7

Step 1: Whisk Your Dry Ingredients Together

Start by preheating your oven to 350°F and lining your baking sheets with parchment paper. Then, whisk the flour, baking soda, cornstarch, and salt in a medium bowl until everything is evenly mixed. This ensures your cookies bake evenly without any surprise pockets of leavening.

Step 2: Cream Butter and Sugars Until Fluffy

In a large bowl, using a mixer, beat the softened butter with the brown sugar and granulated sugar for 2-3 minutes until light and creamy. This step is where magic begins—the air whipped into the butter helps create those tender cookie textures you love.

Step 3: Add Eggs and Vanilla for Richness

Next, beat in the egg, extra egg yolk, and vanilla extract for another 1-2 minutes until fluffy and light. Scrape down the bowl sides occasionally so everything blends well; it’ll make for a smoother batter and consistent cookies.

Step 4: Combine in Dry Ingredients Slowly

With your mixer on low speed, gradually add the dry ingredients to the wet bowl. Mix just until it's combined—overmixing at this stage can make cookies tough, and nobody wants that!

Step 5: Fold In Your Mix-Ins and Prep for Baking

Using a rubber spatula, gently fold in the chocolate chips, toffee bits, potato chips, pretzels, and sprinkles until evenly distributed. For thicker cookies, shape your dough balls into tall ovals instead of rounds when placing on the cookie sheet—it’s a little trick I swear by.

Step 6: Bake and Perfect the Shape

Bake for 10-12 minutes, until the edges are just golden and the tops look set but soft. Once out of the oven, take a large glass and swirl it gently around each warm cookie to create perfectly round edges, then press a few extra pieces of topping on top while the cookies are still warm. Let them cool on a rack for about 5 minutes before enjoying.

Top Tip

From baking dozens of batches, a few small tricks have really helped me nail this recipe every time. The devil’s in the details, so here are my best tips to make sure your Kitchen Sink Cookies turn out spectacular:

Butter Temperature Matters: I’ve learned that leaving butter out for 30-60 minutes until cool to the touch (about 69°F) is the sweet spot—too warm and the cookies spread too much.
Don’t Overmix: When adding the dry ingredients, mix just until combined. Overdoing it makes cookies harder instead of soft.
Shape for Height: Rolling dough into ovals instead of balls makes a thick, chewy cookie you won’t be able to resist.
Sprinkles Only Certain Types: Holiday jimmies work best here because they don’t bleed or melt into the dough, keeping that pretty sprinkle look.

How to Serve Kitchen Sink Cookies Made Easy Recipe

kitchen sink cookies - Serving Suggestion

Garnishes

I personally love adding a few extra sprinkles or chocolate chips right on top of the cookie once they’re warm—it makes the presentation pop and adds that extra special touch. A tiny pinch of flaky sea salt on top can also bring out all the layers of flavor beautifully.

Side Dishes

These cookies pair wonderfully with a cold glass of milk, coffee, or even a scoop of vanilla ice cream for dessert. I’ve also served them alongside fresh fruit to balance out the indulgence, especially when hosting friends.

Creative Ways to Present

For holiday parties, arranging the cookies in a festive tin sorted by mix-in types adds charm. I’ve also rolled mini versions into bite-sized balls and popped them on skewers with marshmallows and pretzels—kids adored the playful presentation!

Make Ahead and Storage

Storing Leftovers

I store leftover cookies in an airtight container at room temperature, and they stay soft and delicious for up to five days. I like layering them between sheets of parchment paper to keep the toppings intact and the cookies from sticking together.

Freezing

For longer storage, freezing is a winner. I freeze unbaked dough balls on a tray first, then transfer them to a freezer-safe bag—this way they don’t stick. When baking from frozen, just add an extra minute or two to the bake time, and you get fresh cookies anytime you want.

Reheating

To warm up leftover cookies, I pop them in a low oven (around 300°F) for 5 minutes or microwave for about 15 seconds. This brings back the melty softness without making them mushy, perfect for that just-baked feeling.

Frequently Asked Questions:

Can I substitute the potato chips or pretzels in the Kitchen Sink Cookies?

Absolutely! I’ve swapped those out with crushed cornflakes or chopped nuts, and it still creates a satisfying crunch. Just choose something with a similar texture to keep that fun contrast.

Why do I need cornstarch in the cookie dough?

Cornstarch gives the cookies extra tenderness and a soft, almost cake-like texture. It’s a small ingredient that makes a big difference—trust me on this one!

What’s the best way to prevent the cookies from spreading too much?

Starting with room temperature butter that’s cool to the touch helps a lot. Also, shaping dough into taller ovals, chilling the dough slightly before baking, and using parchment paper instead of greasing pans keeps the cookies thick and chewy.

Can I make the dough ahead of time?

Yes! You can mix the dough and store it in the fridge for up to 2 days. Just be aware the chips and mix-ins might lose a bit of crunch, but the flavor is still fantastic.
