An OREO cookie is simple to describe and easy to get wrong in the details: two wafers with a creme filling between them. That shape has stayed the same since 1912, while the wafers, the filling, the sizes, and the flavors around it have changed many times. This guide is for someone who wants to understand the cookie before buying it, eating it, or baking with it — what it is, how the types differ, what goes into one, how to eat it, whether it fits a vegan diet, what the label says, and where it came from.
The four core lines are Original, Double Stuf, Golden, and Thins. Everything else on this site — recipes, flavors, comparisons, buying advice — builds on those four. This guide gives an overview. The linked cluster pages cover individual topics in more depth.
What OREO Cookies Are
An OREO cookie is a sandwich cookie made of two wafers and a creme filling. The classic version uses dark cocoa wafers and a pale, sweet creme. The creme is not dairy cream: in the US recipe it is built from sugar, oil, and flavoring, which is why the ingredient list contains no milk or egg — a fact that matters for the vegan and allergen questions below, and one reason the cookie keeps well at room temperature.
There is no single officially confirmed explanation for the name. Published accounts differ, so this guide does not present one origin story as fact. What is documented is the product: first sold in 1912, now sold in many countries, with recipes that vary by market. The US version is the reference for the figures in this guide, because it is the one with the most widely published label. If you buy OREO cookies outside the US, expect differences in sugar, oil, cocoa, and serving size, and read your own pack rather than assuming the US numbers apply.
Main Types and How They Differ
The differences between the core lines come down to three things: the wafer, the amount of filling, and the thickness.
Those four lines — plus Mini and Gluten-Free formats and seasonal limited editions — make up the range. What sets them apart is the wafer, the amount of creme, and the thickness, which is also what decides how each one eats, dunks, and bakes. For the full side-by-side table and a profile of each line, see the flavors pillar. That is why the same cookie can be a plain snack, a dunking cookie, a crust, or a topping — the choice is about what you are doing with it, not about which one is better.
Original is the baseline: the standard creme layer, the darkest wafer, and the flavor most people mean when they say “OREO.” It is also the most useful type for baking, since its wafer crushes into a firm crust and its creme binds a filling without making it runny.
Double Stuf keeps the same wafer and roughly doubles the creme — about twice the standard amount. The result is sweeter and softer, and the cookie holds together a little longer when dunked because the thicker creme cushions the wafers. Per cookie it carries more sugar and more calories than Original, which is the trade-off for the extra creme.
Golden is covered in full on the flavors pillar: vanilla wafers with the original OREO creme.
Thins are a thinner, crisper version of the classic cookie, in chocolate and golden wafer varieties. Each cookie is lighter, so the label serving is four cookies rather than three. They soften fastest in milk and break easily, which makes them better as a snack or a topping than as a dunking cookie or a crust.
Two more permanent formats: Mini OREO, bite-size versions of the classic sold in small packs, and Gluten-Free OREO, launched in the US in January 2021 and certified gluten-free, which uses a different flour blend. For a full side-by-side of the three chocolate lines, see Original vs Double Stuf vs Thins.
Limited editions appear for seasons, holidays, and promotions, then disappear, and their wafers, fillings, and ingredients vary. This site lists only flavors that can be verified; if a flavor is not on the flavors pillar, treat it as unconfirmed rather than assuming it is permanent.
Ingredients and Allergen Awareness
The ingredient list is the only reliable source for what is in a specific pack, and it varies by country. The US list for Original OREO reads, in order: unbleached enriched flour (wheat flour, niacin, reduced iron, thiamine mononitrate [vitamin B1], riboflavin [vitamin B2], folic acid), sugar, palm oil, soybean and/or canola oil, cocoa (processed with alkali), high fructose corn syrup, leavening (baking soda and/or calcium phosphate), salt, soy lecithin, chocolate, and artificial flavor. Ingredients are listed by weight, so flour and sugar come first because there is more of them than anything else.
Two allergens are in the recipe itself: wheat (in the flour) and soy (in the soy lecithin). A third, milk, is not an ingredient in the US recipe, but the cookies are made on equipment shared with milk-containing products, so milk cross-contact is possible. Some packs outside the US carry a “may contain milk” warning for that reason; the US labels checked list only “Contains: wheat, soy.” That cross-contact warning is not an ingredient statement: the maker cannot guarantee the line is free of milk traces, even though milk is not deliberately added.
Read labels in this order: the “contains” statement for allergens in the recipe, the “may contain” statement for what shared equipment can introduce, and the serving size before the calories — every number on the nutrition panel is per serving, not per pack.
Country differences are real: sugar sources, oils, and cocoa levels change between markets, and labeling rules differ, so a figure from a US pack may not match a pack bought elsewhere. When this guide gives a number, it says which country’s label it comes from; otherwise, treat the number as general guidance and check your own pack.
How to Eat and Pair Them
There is no single right way to eat an OREO cookie. The best known is twist, lick, and dunk: twist the wafers apart, eat the creme, then dunk the wafer briefly in milk. Thins soften fastest and Double Stuf holds together longest.
Eating it whole shows the wafer-creme contrast most clearly; breaking it in half works for sharing and tasting. Cold milk is the classic partner; coffee, hot chocolate, and ice cream work the same way, with heat softening the wafer faster. For dunking times and pairings by type, see how to eat OREO cookies.
Crushed wafers make a crust, crushed cookies fold into ice cream and yogurt, and whole cookies top cakes and parfaits. The recipes pillar covers which type suits which dessert — Original gives the firmest crust, Double Stuf adds creme and sweetness to fillings, and Thins work better as a topping than as a crust.
Vegan Status
The vegan question has three separate parts: what the ingredients are, what the maker claims, and what an individual chooses.
The US ingredient list for Original OREO contains no milk, egg, honey, or gelatin, which is why many people call the cookie “accidentally vegan.” Flavored fillings can change the answer, so each variety has to be checked on its own label.
Mondelēz does not label or certify OREO cookies as vegan. The cookies are made on equipment shared with milk-containing products, and Mondelēz notes a risk of milk cross-contact from shared equipment, so the maker will not guarantee the product is free of milk traces.
Whether that fits a vegan diet is a personal choice, not a label claim — some people accept the ingredient list, others do not, because of the shared equipment. A person with a milk allergy should follow the label and their own clinician’s advice, not this page. This guide gives label information, not dietary or medical advice.

Nutrition and Calories
Nutrition figures only mean something with a serving size attached. On the US label, the serving for Original OREO is 3 cookies (34 grams), and every number below is per that serving. Other countries use different serving sizes, so compare labels, not packs.
| Nutrient | Per 3 Cookies (34 g) | Per Cookie (about) |
|---|---|---|
| Calories | 160 | 53 |
| Total fat | 7 g | 2.3 g |
| Total carbohydrate | 25 g | 8.3 g |
| Total sugars | 14 g | 4.7 g |
| Added sugars | 13 g | 4.3 g |
| Protein | 1 g | Less than 0.5 g |
| Sodium | 130 mg | About 43 mg |
Sodium is 130 mg on the current US retail label checked (13.29 oz / Family Size, 2026); an older foodservice edition listed 115 mg, so check your pack for the exact figure. The pattern is the point: most of the calories come from sugar and refined flour, with very little protein or fiber. That is why three cookies feel like a small snack and add up quickly — a second serving doubles everything in the table.
Double Stuf runs about 140 calories per 2-cookie (29 gram) serving, and Golden about 160 calories per 3-cookie serving. For the full variety-by-variety breakdown, see OREO cookies nutrition and calories.
Two practical notes: the label’s 160 calories is for three cookies, not for the pack, and a pack holds several servings. The cookie is primarily an energy-dense treat, with most calories coming from sugar and fat. It is not a significant source of protein, fiber, or most micronutrients.
A Brief Verified History
The dates below are based on published historical sources. Verify current product details against the package.
The chocolate sandwich cookie predates OREO: Hydrox, made by the Loose-Wiles Biscuit Company, appeared in 1908 and was the first chocolate sandwich cookie sold in the US. OREO followed four years later, and the two competed for decades — OREO was not the first of its kind, and the comparison page covers the two cookies side by side without taking a side.
- March 6, 1912: the first OREO is sold to a grocer in Hoboken, New Jersey. It was made by the National Biscuit Company (Nabisco) at its Chelsea factory in New York City and sold in bulk tins by weight.
- March 14, 1912: the name is filed for trademark; it is registered on August 12, 1913.
- 1921: the product is renamed the Oreo Sandwich.
- 1974: Double Stuf is introduced, with about twice the creme of the original.
- 2004: Golden arrives, replacing the chocolate wafers with vanilla ones.
- July 2015: Thins arrive as a thinner, crisper version.
- January 2021: Gluten-Free OREO launches in the US, certified gluten-free.
OREO was created by the National Biscuit Company (Nabisco). In December 2000, Philip Morris Companies (then the parent of Kraft Foods) acquired Nabisco for $18.9 billion ($14.9 billion in cash for shares, plus about $4.0 billion of assumed debt) and merged it into Kraft Foods. On October 1, 2012, Kraft Foods Inc. spun off its North American grocery business and renamed itself Mondelēz International, and OREO became part of Mondelēz’s portfolio. Today the cookie is sold in many countries under the same name, with recipes adjusted to each market. This site is not affiliated with Mondelēz or OREO.

Choosing the Right Type
For a side-by-side comparison of the lines, see the flavors pillar. For baking, Original gives the firmest crust, Double Stuf adds sweetness and creme to fillings, and Thins are better sprinkled on top than pressed into a base.
If you are choosing between the three chocolate lines, the Original vs Double Stuf vs Thins comparison puts them side by side on filling, texture, and use. The flavors pillar covers the full product range, the recipes pillar shows which type suits which dessert, and the buying and storage guide covers where to buy and how to keep an opened pack fresh — this guide does not repeat that.
The simplest rule is also the oldest one: buy a small pack of the type you have not tried, eat it plain first, and decide from there.
