The Classic Reese's Peanut Butter Cup and Dairy
For those wondering, the classic milk chocolate Reese's Peanut Butter Cup is not dairy-free. The ingredients clearly list multiple dairy components in its milk chocolate shell. These ingredients are the source of the classic cup's rich and creamy chocolate flavor, but they make it unsuitable for anyone following a vegan diet or with a milk allergy.
Key dairy ingredients found in the milk chocolate of classic Reese's Peanut Butter Cups include:
- Skim milk
- Milk fat
- Lactose (milk sugar)
- Reduced protein whey (in some versions and other Reese's products)
The Rise of Dairy-Free Reese's Options
In recent years, the Hershey Company has expanded its product line to include options for those avoiding dairy. This is a significant development for consumers who previously couldn't enjoy the brand's signature peanut butter and chocolate flavor combination.
Reese's Plant-Based Peanut Butter Cups
In 2023, Hershey's introduced a plant-based Reese's Cup made with oat chocolate instead of traditional milk chocolate. This product retains the classic peanut butter filling while substituting the dairy-based outer layer with a creamy, oat-based alternative. These cups are marketed toward vegan consumers and those with dairy sensitivities.
Other Reformulated Reese's Products
Beyond the specific plant-based cup, other products have undergone recipe changes to eliminate dairy:
- Reese's Pieces: As of mid-2025, Hershey's reformulated Reese's Pieces to be dairy-free in the U.S. and Canada. However, the candy may still contain confectioner's glaze (derived from insects), so it is not considered vegan by all standards. Always check the packaging for the most current information.
- Reese's Peanut Butter Baking Chips: The standard baking chips also transitioned to a dairy-free recipe around mid-2025. Like other products, it is essential to check the label, as older inventory may still be available.
Understanding Cross-Contamination Warnings
For individuals with severe milk allergies, simply choosing a "dairy-free" product might not be enough. Most of Hershey's products, including dairy-free versions, are processed in the same facilities. This creates a risk of cross-contamination with milk allergens.
Always read the label carefully. Look for allergen statements that say "Manufactured on shared equipment with milk" or similar warnings. For those with a severe allergy, consulting the manufacturer directly or avoiding the product altogether may be the safest option.

Making Your Own Dairy-Free Peanut Butter Cups
For those who want a completely risk-free dairy-free experience or simply prefer to control their ingredients, making homemade peanut butter cups is a delicious alternative. Many online recipes use dairy-free chocolate chips and simple peanut butter to create a treat very similar to Reese's. You can find excellent recipes on websites like Minimalist Baker or Go Dairy Free, which offer vegan and allergy-friendly baking inspiration.
Conclusion: The Final Verdict on Dairy in Reese's
In summary, the classic Reese's Peanut Butter Cup does contain dairy and is not suitable for those with milk allergies or on a vegan diet. However, the market has evolved, and the Hershey Company has responded with new options. The Reese's Plant-Based Peanut Butter Cups are certified vegan and dairy-free, and other products like Reese's Pieces and baking chips have also been reformulated to remove dairy. It is critical for individuals with severe milk allergies to read all packaging carefully and be aware of potential cross-contamination risks from shared manufacturing equipment. By understanding the different product lines, consumers can make informed choices to satisfy their sweet cravings safely.
