This three-ingredient frozen treat turns your favorite sandwich combo into bite-sized cups you'll love. When you take a bite, the coconut oil gives a satisfying crack, while the smooth peanut butter paired with sweet jam brings back that childhood PB&J magic we can't get enough of.
I started making these cups for my kids' playdates on stormy days as a better option than candy from the store. Now they vanish almost as fast as I can put them together when friends come over.
Ingredients
- Coconut oil: This creates that wonderful firm structure that keeps everything in place
- Unsweetened peanut butter: Brings rich taste and healthy fats stick with natural kinds for best outcomes
- Fruit-sweetened jam: Adds natural sweetness without processed sugar pick quality brands for top-notch flavor
- Optional salt: Boosts all the tastes and makes that can't-resist sweet-salty combo
- Optional coarse salt topping: Adds a fancy touch that makes the whole treat better
Step-by-Step Instructions
- Prepare Muffin Liners:
- Put 10 paper liners in a regular muffin tin or set up 10 silicone cups on a baking sheet, making sure they're steady and all set for filling.
- Create Peanut Butter Mixture:
- Warm the coconut oil in a small pot on low until it just turns liquid. Mix it right away with the peanut butter until totally smooth. Throw in a bit of salt if your peanut butter doesn't have any to make the taste pop.
- Form Base Layer:
- Put one tablespoon of your peanut butter mix into each cup, making sure it's level on the bottom. Stick the whole tray in the freezer for exactly 10 minutes until the base gets somewhat firm.
- Add Jam Center:
- Take the tray out when the bottom layer feels solid but isn't fully frozen. Drop two teaspoons of jam in the middle of each cup. Use your spoon back to spread the jam without pushing it all the way to the edges.
- Complete The Cups:
- Cover each cup with another tablespoon of peanut butter mixture, making sure the jam gets totally covered. For the best look, start pouring in the middle and let it spread out naturally.
- Freeze And Set:
- Put the tray back in the freezer for at least 30 minutes to get completely hard. If you want to add coarse salt, sprinkle some on after about 5 minutes in the freezer when the tops are starting to firm up.

Coconut oil truly works wonders in these little treats. I found out how important it was when I first tried making them with just peanut butter and jam. Without adding coconut oil, they never set right and turned into something tasty but super messy for everyone to eat.
Storage Tips
You can keep these PB&J cups in the freezer for up to 3 months in a sealed container. I like to put parchment paper between layers so they don't stick together. If you want them a bit softer, keep them in the fridge instead, but they'll be much less firm and should be eaten within 2 weeks.
Substitution Ideas
What's great about this treat is how easy it is to change things up. Go for almond butter if you want something a bit fancier or try sunflower seed butter if you can't have nuts. Any jam works too - raspberry gives a nice tang, while apricot adds an interesting sweetness. You could swap coconut oil for cacao butter, but that'll make them taste more like chocolate.
Serving Suggestions
These cups taste awesome straight from the freezer when it's hot outside, but let them sit out for about 5 minutes before eating in colder weather. They go great with a cup of tea or coffee in the afternoon. For something extra fancy, put a cup on a small plate with some fresh berries and a tiny bit of whipped coconut cream.
