If you're doing much baking this holiday season, you're probably going through countless bags of flour and sugar, and there's really no place to replenish your baking supplies like Costco.

Members of America's leading warehouse club can take advantage of wholesale deals to load up on tons of baking basics in big quantities, along with exclusive low prices on specialty products.

These 14 must-have baking staples will elevate all your cakes, cookies, and pies. (Note that items can be regional, so some products may differ in availability and price.)

Pure Vanilla Extract

Seasoned bakers can tell the difference in taste between imitation and pure vanilla extract. This flavoring may as well be liquid gold, as a single ounce will typically run you around $3 to $4. Before you resort to sourcing your own vanilla beans to make the extract yourself, consider Costco's five-star Pure Vanilla Extract, which costs just $16.99 for a 16-ounce bottle. You do have to buy two bottles minimum, but then you'll likely be set for the next few years of confections.

Nielsen-Massey Madagascar Bourbon Pure Vanilla Bean Paste

Some fans on Reddit call Nielsen-Massey "the Champagne of vanilla." The family-owned company offers Costco members a chance to buy its vanilla bean paste for about half the price as other retailers. For an eight-ounce jar, it's only $36.99 online. If you look out for sales, sometimes you can snag an even sweeter deal. For a limited time last year, Costco slashed the online price by $10.

How do you use vanilla paste? It's not a substitute for regular vanilla extract, but a scoop of this premium paste from Madagascar will import a richer vanilla flavor and add the telltale flecks of vanilla beans to your frostings, custards, and cakes.

Maldon Kosher Sea Salt Flakes

For a gourmet touch on cookies, caramel, and brownies, Maldon is the finishing salt of your dreams, but you'll usually pay a pretty penny for the English-crafted spice. That is, unless you buy it at Costco.

"I was blown away when I saw 1.25 pounds of Maldon salt for $7.79 today at my California store," wrote one West Coast shopper, after spotting a tub of the pyramid flakes at the warehouse this past August. "I just bought an 8 ounce pack for $8 at World Market earlier in the week. If you've never had Maldon finishing salt.. get it NOW!" Costco hasn't listed the elusive item on its website, but if you give a call to your warehouse, you can find out if it's coming to a store near you soon.

Out of all the types of cinnamon in the world, this organic Vietnamese-based spice is the most potent and aromatic, and it's been well-loved by Costco shoppers for years. "This is by far the best Cinnamon I've ever had," wrote one reviewer. "I put a pinch in my coffee every morning. I tried other brands but nothing can compare." It comes in a pack of two 10.7-ounces containers for $19.99 online, which may be enough to last you over a decade, according to some Reddit users.

When it comes to pastries, the quality of your butter can make a noticeable difference in taste and texture. So, skip the standard spread and try this 95% grass-fed New Zealand butter from Costco's store brand Kirkland Signature. The popular private label is well known for its high-quality, low-priced products. Kerrygold is often the gold standard for premium butter among Costco shoppers, but according to All Recipes, the Kirkland version is a solid substitute that saves you $1 per stick of butter, at around $10 per box.

Kirkland Signature Almond Flour

Almond flour is a key component for certain gluten-free treats, but it can cost almost $10 per pound at other grocers. Costco sells this three-pound bag of superfine almond flour for $12.99. The flour contains only one ingredient: blanched almonds. Experienced bakers say it doesn't act as a replacement for regular flour in all cases, but they can vouch for the quality of this Kirkland ingredient in recipes that call for the alternative.

"I use it all the time for banana bread. It's amazing!" wrote one fan on Reddit. It's a hefty bag, though, so you might want to stash it in your freezer to keep it fresh for longer, according to another Reddit user.

Rodelle Gourmet Baking Cocoa Powder

You're not going to find a better deal on 100% cocoa than this premium baking cocoa powder. The specialty chocolate is Dutch-processed, which neutralizes the natural acidity of cocoa, making the color darker and the flavor richer and smoother. Costco members will pick this 25-ounce bag up for only $8.49. At Walmart, the same product costs nearly three times more.
