About Peanut Butter and Chocolate Day
National Peanut Butter and Chocolate Day takes place on Thursday, 23 July 2026, celebrating one of the most beloved flavour pairings in confectionery. Observed primarily across the United States, this food holiday honours the salty-sweet combination of creamy peanut butter and rich chocolate, made famous by the Reese’s Peanut Butter Cup. It is a light-hearted excuse to bake, buy, and share treats that bring the two ingredients together.
How to Celebrate Peanut Butter and Chocolate Day
This is a day built for indulgence, so the best way to mark it is to get the two ingredients onto a plate. Here are plenty of ways to take part.
- Treat yourself to a Reese’s Peanut Butter Cup – The candy that started it all is the simplest tribute. Pick up a pack, pop one in the freezer for a firmer bite, or try one of the many spin-off products such as Reese’s Pieces or peanut butter eggs.
- Bake peanut butter and chocolate brownies – Swirl spoonfuls of peanut butter through your brownie batter before baking for a marbled finish. The contrast of fudgy chocolate and salty peanut butter is hard to beat.
- Make no-bake peanut butter chocolate bars – Combine peanut butter, melted butter, icing sugar and biscuit crumbs for the base, then top with melted chocolate. Chill and slice for a crowd-pleasing treat with no oven required.
- Whip up a peanut butter and chocolate milkshake – Blend chocolate ice cream, milk and a generous spoonful of peanut butter for a thick, decadent drink. Top with whipped cream and a drizzle of chocolate sauce.
- Try a savoury-sweet twist – Spread peanut butter on toast and grate dark chocolate over the top, or dip pretzels in melted chocolate and peanut butter for the perfect balance of salty and sweet.
- Host a dessert swap – Invite friends round and ask everyone to bring a different peanut butter and chocolate creation. Cookies, cheesecake, fudge and lava cake all work beautifully, and you get to sample them all.
- Bake peanut butter blossom cookies – These classic American cookies are rolled in sugar and topped with a chocolate kiss pressed into the centre while still warm. They are quick to make and instantly recognisable.
- Share the love on social media – Photograph your creations and post them to inspire others. The day is as much about spreading enthusiasm for the pairing as it is about eating it.
What is Peanut Butter and Chocolate Day?
Peanut Butter and Chocolate Day, often listed as National Peanut Butter and Chocolate Day, is an unofficial food holiday dedicated to the union of two ingredients that many people consider a perfect match. It is celebrated each year on 23 July, mainly in the United States, where the pairing has deep roots in the confectionery industry. The day appeals to home bakers, candy fans, and anyone with a sweet tooth, and there is no formal organisation required to take part. It sits alongside a calendar of single-ingredient food days, including the separate National Peanut Butter Day in January and various chocolate celebrations throughout the year.
When is Peanut Butter and Chocolate Day?
Peanut Butter and Chocolate Day falls on Thursday, 23 July 2026. The date is fixed, so it lands on 23 July every year regardless of the day of the week. Because it is an informal observance rather than a public holiday, there are no official events or closures attached to it. If you enjoy themed food days in July, you might also like National Hot Fudge Sundae Day, which arrives just two days later on 25 July.
The History of Peanut Butter and Chocolate Day
The story of the day is really the story of the flavour combination itself, and that traces back to one man: Harry Burnett Reese. A former dairy farmer and shipping foreman who worked for chocolate magnate Milton S. Hershey, Reese began experimenting with confectionery in his basement in Hershey, Pennsylvania. He founded the H.B. Reese Candy Company in 1923 and, from the outset, used Hershey chocolate in his sweets.
In 1928, Reese created the peanut butter cup, a disc of peanut butter coated in chocolate. The product was originally sold as a “penny cup” because each one cost a single cent. It proved so popular that by 1942, with wartime rationing straining his other product lines, Reese discontinued his other chocolates to focus entirely on the peanut butter cup. After his death in 1956, his six sons took over the business, and in 1963 they sold the company to Hershey’s for around 23.5 million dollars. The Reese’s Peanut Butter Cup went on to become one of the best-selling sweets in the United States.
The awareness day itself is far more recent and emerged in the era of internet food holidays, with sources placing its establishment around 2016. Like many such days, its exact founder is unclear, but it spread quickly online as bakers, brands, and food fans embraced any excuse to celebrate the pairing. Today it is widely listed across food calendars and marked by home cooks and confectioners alike.
Fun Facts About Peanut Butter and Chocolate Day
- The first Reese’s Peanut Butter Cups were sold for just one cent each and were marketed as “penny cups”.
- H.B. Reese reportedly created the cups after learning that a confectioner had supply problems making a similar peanut butter and chocolate candy, spotting a gap in the market.
- Reese always used Hershey’s chocolate in his sweets, a habit dating back to his time working on a Hershey dairy farm.
- The Reese family sold the company to Hershey’s in 1963 for around 23.5 million dollars, equivalent to a far larger sum today.
- The appeal of the pairing is often attributed to the contrast between the bitter notes of chocolate and the salty, creamy sweetness of peanut butter, which stimulates multiple taste sensations at once.
- Peanut butter and chocolate appears in countless formats beyond the cup, including ice cream, protein bars, spreads, cereal, and even savoury sauces.
Why Peanut Butter and Chocolate Day Matters
While it is a fun and informal observance, the day is a small celebration of culinary creativity and the joy of sharing food. It gives home bakers a reason to try new recipes, supports independent chocolatiers and confectioners who lean into the theme, and brings people together around a flavour combination that crosses generations. At its heart, it is a reminder that some of the best things in life come from pairing two simple ingredients.
