It's officially autumn, and if you live somewhere that experiences all four seasons, you're likely seeing evidence of this in the changing colors of the leaves and the chill in the air each morning. And even if you live in a perpetually warm climate, you must have at least noticed that it's getting darker a lot earlier. All this means that Halloween is coming soon, and after that come the big baking holidays of Thanksgiving and Christmas. And that's where Costco can be a huge help.

If you celebrate either (or any other holiday that falls during autumn or winter) and you've been put in charge of cookies or pies in the past, then you might have experienced the sheer horror of being up to your elbows in flour, only to discover that you're out of an essential ingredient. However, if you'd done your stocking up at Costco, because the warehouse chain sells bulk quantities of these types of goods, you'd be hard-pressed to find yourself running out before January. And it's not just essentials like flour and salt; Costco carries a variety of baking sheets, bread pans, and even casserole dishes suitable for dense and fudgy brownies, so if you've been looking to replace old kitchen workhorses, now is a great time. Let's get into it!

If you look into the future and see that you'll be baking a lot of chocolate chip cookies (or cookies that contain chocolate chips), you'll definitely want to pick up a 4.5-pound bag of Kirkland Signature semisweet chocolate chips, or maybe even two. These chocolate chips come highly recommended by Costco customers, with over 200 five-star reviews.

Kirkland Signature Semi-Sweet Chocolate Chips are available at Costco for $11.99.

The first thing you'll likely notice about this baking set is how pretty it is, with attractive floral designs inside and out. Then, once you actually start to use it, you'll see how practical all the different pieces are, from the loaf pans for nut-studded pumpkin bread to the casserole dish for dessert bars. And with their high sides, you won't have to worry about any spills while baking.

Farmhouse Floral 5-Piece Oven to Table Set is available online only on Costco's website for $42.99.

Perhaps one of the most widely recognized baking supply brands in the country, Clabber Girl is best known for its baking powder, but it also manufactures cornstarch. This 3-pound bucket is not only enough to keep you baking until the second coming, but it's also a lot less messy than the boxes in which this ingredient often comes packaged.

Clabber Girl Corn Starch is available at Costco for $6.59.

Your holiday bread baking will get a beautiful upgrade with this cast iron oven set from Tramontina, which comes in two shades: Dark Red and Beige. Not only does it include the lidded bread oven, but it also solves the problem of where you're going to put the thing when it's still hot, thanks to an oblong, purpose-made wooden trivet.

Tramontina Enameled Cast Iron Bread Loaf Oven and Trivet Set can be purchased online on Costco's website for $63.99.

While we're on the topic of bread baking, you'll end up with a flat loaf if you don't add yeast to the dough and allow it to do its work, and there's likely enough in this bag to make over a hundred loaves. Not only that, but the fast-acting yeast here is a real time-saver, cutting down on rising times by as much as half in some cases.

You can purchase a bag of Saf-Instant Yeast at Costco for $4.99.

Nielsen-Massey is one of the most trusted premium brands of vanilla baking products on the market today, and the fact that you can find its Mexican vanilla extract at Costco is a pure win for bakers. Each package contains two 8-ounce bottles, which will fill your cookies and cakes with warmth and richness.

Nielsen-Massey Mexican Pure Vanilla Extract is available only on Costco's website for $54.99.

A sprinkling of flaky sea salt can work wonders on top of blondies or triple chocolate brownie batter cookies, balancing their sweetness and adding a delightful texture to the otherwise soft baked goods. This Olde Thompson Flake Sea Salt comes in a hefty 5-pound container, which shouldn't need to be thrown out for a good long time with proper storage.

Olde Thompson Kosher Flake Sea Salt is available at Costco for $8.99.

For all your blackout cakes, brownies, or cookies that require the deep, rich flavor of chocolate, reach for a bag of this Rodelle Gourmet cocoa powder, which includes over a pound of the good stuff.

Rodelle Gourmet Baking Cocoa Powder is available at Costco for $14.99.

Naturally, you won't get very far in your autumn or winter baking without a solid foundation upon which to build your recipes — in this case, a good all-purpose flour. Kirkland Signature's version is both organic and kosher, and comes packaged in two 10-pound bags, for a total of 20 handy pounds that'll keep your pantry well-stocked for the foreseeable future.

Kirkland Signature Organic Unbleached All Purpose Flour can be purchased at Costco for $19.99.

Have gluten-free friends or family who want to enjoy cookies and pastries just like everyone else? Then get your hands on one of these 3-pound bags of Kirkland Signature Almond Flour. If you see it in stores, it's best not to wait until your next trip to pick some up, though — customers have reported that this product is getting harder to find.

Kirkland Signature Almond Flour is available at Costco for $16.49.
