Do Reese's Peanut Butter Cups Have Red 40?

4 min read

Over the past decade, a growing number of consumers have started paying closer attention to artificial dyes in their food. A common question among these consumers is, "Do Reese's Peanut Butter Cups have Red 40?" The answer is more nuanced than a simple yes or no, as it depends on the specific Reese's product in question.

Quick Summary

The Original Reese's Peanut Butter Cups do not contain Red 40 dye, while several other Reese's-branded products, like Reese's Pieces and certain stuffed variations, do.

Key Points

  • Original Cups vs. Reese's Pieces: The classic Reese's Peanut Butter Cups do not contain Red 40, but many other Reese's-branded candies, most notably Reese's Pieces, do.

  • Check the Label: Due to ongoing ingredient changes and variations between products, the most reliable method for determining dye content is to check the ingredient label on the specific package you are purchasing.

  • Red 40 vs. Red 40 Lake: Red 40 is a water-soluble dye, while Red 40 Lake is an insoluble pigment used in candy coatings like those on Reese's Pieces.

  • Why Variation Exists: Ingredient differences are driven by product development, as different products require different formulas for specific textures and aesthetics, such as the crunchy shell of Reese's Pieces.

  • Hershey's Commitment: The Hershey Company has publicly committed to using natural food colors in its products, though the transition is happening gradually and is not yet complete across all product lines.

  • Specialty Products: Seasonal and limited-edition Reese's products can have different ingredient formulations from the classic cups, potentially including artificial colors.

Understanding the Ingredients in Reese's

When it comes to the iconic Reese's brand, the ingredients can vary significantly depending on the specific product. The primary reason for confusion is that while the classic peanut butter cups are typically dye-free, other candies under the Reese's name contain artificial colors like Red 40. It is crucial to check the ingredient label of each item to determine its contents, a practice encouraged by Hershey's itself, especially during product transitions.

Ingredients of the Classic Reese's Peanut Butter Cup

According to recent ingredient lists, the standard, two-cup Reese's Peanut Butter Cup does not list any artificial dyes, including Red 40. Its ingredients typically include:

  • Milk chocolate (sugar, cocoa butter, chocolate, skim milk, milk fat, lactose, soy lecithin, PGPR, natural flavor)
  • Peanuts
  • Sugar
  • Dextrose
  • Salt
  • TBHQ and citric acid (to maintain freshness)

Ingredients of Other Reese's Products

Conversely, products like Reese's Pieces are known to contain artificial colorants. For instance, a typical ingredient list for Reese's Pieces includes:

  • Artificial color (Yellow 5 Lake, Yellow 6 Lake, Red 40 Lake, Blue 1 Lake)
  • Partially defatted peanuts
  • Sugar
  • Hydrogenated vegetable oil
  • Corn syrup solids

Another example is the seasonal or specialty Reese's varieties. The Hershey's Chocolate World website, for instance, lists a "Reese's Stuff Your Cup" option that includes artificial colors.

The Difference Between 'Red 40' and 'Red 40 Lake'

When reading ingredient labels, you may notice "Red 40" or "Red 40 Lake." It is important to know the difference. Both are derived from the same source, but they have different applications in food production. Red 40 is a water-soluble dye, while Red 40 Lake is an insoluble pigment. This distinction affects how they are used and can explain why certain products, like the shells on Reese's Pieces, contain the 'Lake' version. Some individuals may have sensitivities to one or both, and it is wise to consult a healthcare professional if you have concerns.

Comparison Table: Classic Cups vs. Reese's Pieces

To clarify the ingredient differences, here is a comparison table of the classic Reese's Peanut Butter Cups and Reese's Pieces.

Feature Classic Reese's Peanut Butter Cups Reese's Pieces
Artificial Dyes? No Yes (e.g., Red 40 Lake, Yellow 5 Lake, Yellow 6 Lake, Blue 1 Lake)
Primary Ingredients Milk chocolate and peanut butter Partially defatted peanuts in a sugar shell
Chocolate Content Contains milk chocolate Contains no chocolate
Texture Soft, smooth peanut butter and chocolate Crunchy candy shell with a peanut butter center
Target Audience Broad consumer base Often featured in recipes and as a standalone candy

Why Ingredient Variations Exist

Hershey's manufactures a vast array of products under the Reese's brand, and the ingredients are formulated to achieve specific textures, tastes, and appearances for each one. The crunchy, colorful shell of Reese's Pieces necessitates the use of artificial dyes for its distinct look and feel. The classic peanut butter cup, on the other hand, does not require these colors. The differences are not an oversight but a deliberate choice driven by product development and market demands.

Hershey's Move Toward Natural Colors

In recent years, The Hershey Company has made a public commitment to switch to natural food colors. As of 2025, changes are still ongoing, and many products, particularly those with vibrant colors like Reese's Pieces, continue to contain artificial dyes. The company has advised consumers to check the label for the most accurate and up-to-date ingredient information. This transition signifies a broader industry trend toward addressing consumer concerns about artificial additives.

The Final Verdict on Red 40 in Reese's

Ultimately, whether a Reese's product contains Red 40 depends entirely on which specific item you purchase. The original cups are dye-free, while others, particularly those with a colorful candy coating, do. For those with allergies or sensitivities, reading the label is the only surefire way to know for certain. The variety of Reese's products means consumers can find options that align with their dietary preferences, though vigilance is required for colored products. To learn more about this industry trend, consider reviewing information directly from The Hershey Company regarding their ingredients and transition plans.

Conclusion

The simple query, "Do Reese's Peanut Butter Cups have Red 40?" reveals a complex reality within a major confectionery brand. The classic cups are free of artificial dyes, including Red 40. However, specialty products and colorful candy versions like Reese's Pieces do contain this and other artificial colorants. This distinction emphasizes the importance of reading product labels carefully to make informed dietary decisions, especially with brands that have multiple product lines. With Hershey's gradual shift towards natural colorings, consumers can expect to see more changes in the future, but for now, checking the label is the most reliable approach.
