Top 14+ best Costco treats when hosting a kid's birthday party on a budget

Kirkland Signature bakery gourmet chocolate chunk cookies

Costco's bakery is a top choice for economical, fresh goods, and the bakery chocolate chunk cookies are no exception. The large, semi-soft cookies have satisfying chocolate chunks (not chips) and come in a 24-count pack. Leave them in the plastic container for ease, or if you're feeling up for it, enhance the experience by placing them on a plate for a more grab-and-go-friendly treat. To reduce waste, cut them in half so kids grab one half at a time. Even if it is budget-friendly, you don't want a kid to take a bite and throw the rest of the cookie away. Believe me, this happens a lot. 

While Costco has a cookie variety pack, which includes chocolate chunk, oatmeal raisin, and double nut cookies, stick with the chocolate chunk pack; it's an approachable flavor that most guests will like regardless of their age. You could also go with the mini chocolate chip cookies that come in a 60-count. This saves you the time of cutting them in half, and they are pretty cute, too.

Mott's fruit snacks

Fruit snacks are an absolute staple for kids and toddlers, so it makes sense that you can utilize them at a birthday party as well. They come in individual bags, so you can leave them in the food area or on the table for people to have a quick snack. Each kid can get their own without fighting over colors or flavors. Costco sells a few fruit snacks and fruit bar options, but the 90-count Mott's fruit snacks are a great way to stretch a dollar because you get a lot of packets for the price. 

As a plus, they are gluten-free, gelatin-free, and free from artificial flavors or colors, which can make the fruit snacks a wonderful option if you have any guests with allergies or dietary sensitivities. They come in fruit and vegetable shapes, such as carrots and pears, so they are pretty cute to boot. Some reviews mention that they have an inconsistent amount per packet. If this is a concern, open a few at a time and place them on a plate for kids to nibble on. You'll have plenty left over to add to your kids' lunch boxes, too.

Sensible Portions Garden Veggie Straws

When you want to serve an inexpensive, savory treat at the party, then Garden Veggie Straws by Sensible Portions is a top pick. This pack includes 42 individual portions, making them ideal for portable snacks if you're having an outdoor celebration in a park. These are gluten-free, free from artificial flavors or preservatives, and kosher, which is a delightful option for those with certain dietary needs. Let's be honest — most people love a savory crunchy snack, whether they're kids, teens, or adults.

The sticks have a vegetable component and are also potato-based, so these simply make an alternative to your standard chip. Kids can easily hold onto the elongated straw shape, and the different green, yellow, and orange colors add a playful touch. These are incredibly tasty and marvelously crunchy. The Garden Veggies Straws have a light veggie flavor, particularly the green one, which has a mild spinach taste, but they're easily palatable for children.

Nature's Garden Probiotic Strawberry Yoggies

Nature's Garden Probiotic Strawberry Yoggies make a stand-out option because of the ingredients and nutrients. It's made with real strawberry pieces and yogurt for a sweet, tangy treat. It's not a yogurt cup and not a gummy-based fruit snack, but it still brings the creamy, chewy qualities into the mix. The package comes with 30 packets, so you can set aside one pack for each guest.

Since Yoggies have fiber and probiotics, the individual portions are a big plus, ensuring that guests — adults and kids alike — don't consume too much. The 30-count allows you to set out one pack per person without the risk of eating too many. Reviews mention that kids and toddlers of various ages like them, so the yogurt balls can bring nutritional value to your party when you want something that strays from your average snack.

Nutella and Go! hazelnut and cocoa spread with breadsticks

Nutella and Go! hazelnut and cocoa spread with breadsticks can make a tasty option for outdoor parties when you need a self-contained and easy-to-grab snack. Costco sells them in a pack of 16, and they sometimes go on sale, making them even more cost-effective. These offer a unique eating experience since you have to dip the crunchy breadsticks into the sweet, nutty Nutella. The dippers are not only fun, but they're delicious, too. Together, they are a nice blend of crispy, creamy, and smooth for a playful combination of textures. I keep these stocked, and everyone loves them. 

These are ideal when you don't want to have to do any dishes or preparation — just make sure to have napkins handy since they can get messy on the fingers, particularly at the end (and especially for those with small fingers). Nutella and Go! packs are a fantastic choice for all ages, as both parents and kids can appreciate the familiarity of the hazelnut cocoa spread. If your kid likes Nutella, these snacks make a captivating and fresh way to eat it. 

Entenmann's Little Bites Party Cake Muffins

Costco sells a couple of Entenmann's Little Bites flavors, but we think the Party Cake Muffins are extra festive since we're talking about a kid's birthday party. But Little Bites are a big hit amongst kiddos no matter the flavor, so you could opt for the chocolate chip version if that's your child's preferred flavor. Both boxes have a 20-count of the muffin pouches, with four muffins in each bag.  

You could hand out individual pouches for mess-free treats or remove the bags and arrange them on a plate or tray. These are deliciously bite-sized, so you don't have to worry about giving kids those enormous Costco bakery muffins. The Little Bites muffins are kosher and don't contain high fructose corn syrup. It's more economical to purchase them in bulk from Costco than pick up individual packs from the grocery store. Although these are a staple to pack in school lunches, they are just as delicious and enticing at a birthday party.

Kirkland Signature organic whole milk

Aside from juice and water, the kids may want to sip on milk to pair with the delicious food and snacks, especially the cookies. Milk is a child's familiar favorite and quite economical to purchase at Costco, especially if you get the Kirkland Signature organic whole milk 18-count. These come in convenient individual 8-ounce cartons, so kids can have their share without crying over spilled milk. 

The packs reduce wasted milk and keep your party costs down. Whole milk contains natural sugar, but they're not as sweet as juice, making it a vitamin-packed choice if you don't want something cloying. The Kirkland one is several dollars cheaper than the name-brand Horizon organic milk 18-count, making it a low-cost beverage. Another great quality about the Kirkland milk packs is that they can be stored unrefrigerated leading up to the party. Place them in the fridge the night before so they are cold upon serving.

Tropical Fields organic crispy coconut rolls

Now, we know that coconut isn't always a favorite, but the Tropical Fields organic crispy coconut rolls with roasted black sesame seeds are perfect for parties. They're easy to hold onto but look sophisticated enough to feel like an elevated snack. Since they are gluten-free and dairy-free, they make a solid choice for people with certain food sensitivities. The rolls have a tropical, nutty profile because of the blend of coconut and sesame seeds, so they bring a refreshing flavor. 

They're airy and light with a wafer-like texture; the whole package weighs 11 ounces, but you still get a good amount of the rolls. You could serve them as they come for fuss-free eats or crumble them over ice cream or yogurt bowls. People on TikTok even say you can dip them in Nutella or chocolate to give them a sweeter profile. This organic snack is a terrific way to offer a crunchy treat that isn't candy.
