These vibrant purple bars transform the classic crispy marshmallow squares with the unique nutty, vanilla essence of ube (purple yam). The Filipino-inspired jam creates stunning color and subtle earthy sweetness that pairs beautifully with gooey marshmallows. The entire process takes just 20 minutes from start to finish—simply melt butter with marshmallows, swirl in vibrant ube halaya, fold in crispy rice cereal, and press into a pan. Optional white chocolate drizzle and toasted coconut add extra flair. The result is 16 chewy, colorful squares that offer a delightful fusion of American comfort food and Filipino flavors.
The first time my friend Mia brought these to a potluck, everyone gathered around the purple squares like they were some kind of cosmic discovery. Someone actually asked if they were from a fancy bakery, and Mia just laughed and said, "Nope, just Rice Krispie Treats with a Filipino twist."
I made these for my daughters birthday last year, and her friends kept taking pictures before anyone would actually eat them. One girl whispered, "Is it safe to eat purple food" and then proceeded to have three squares.
Ingredients
- 6 cups crispy rice cereal: The foundation of everything magical about childhood snacks, get the crispiest brand you can find
- 4 cups mini marshmallows: Mini marshmallows melt faster and more evenly than the big ones, saving you from those stubborn unmelted lumps
- 1/4 cup unsalted butter: Butter adds richness that you just cant get from oil, and unsalted lets you control the salt level
- 1/3 cup ube halaya: This purple yam jam is the soul of the recipe, bringing that distinct flavor that reminds me of morning breakfasts in Manila
- 1/2 teaspoon ube extract: Optional but worth it if you want that vibrant purple color that makes people do a double take
Instructions
- Prep your pan like your sanity depends on it:
- Grease a 9x9 inch pan thoroughly with butter or nonstick spray, getting into all the corners because these treats will stick to anything thats not ready for them
- Melt your foundation:
- Melt the butter in a large saucepan over low heat, then dump in the marshmallows and stir constantly until theyve completely surrendered into a smooth, glossy pool
- Make it purple:
- Stir in the ube halaya and extract if youre using it, watching as the white mixture transforms into this incredible violet color that looks like something out of a storybook
- Bring it all together:
- Pull the pan from the heat and immediately fold in the cereal, using a spatula to gently coat every piece until the marshmallow has claimed everything evenly
- Press into reality:
- Transfer the mixture to your prepared pan and press it down firmly with a greased spatula, really getting in there to create an even surface that will cut perfectly
- Add the flourish:
- Drizzle melted white chocolate over the top if youre feeling fancy, then sprinkle with toasted coconut flakes for this gorgeous contrast of white on purple
- Practice patience:
- Let the treats cool completely for at least an hour before cutting into 16 perfect squares, or sooner if you like them warm and gooey
My grandmother saw these on my counter and asked if I was making playdough, but after one bite she declared them better than the original recipe shes been making for forty years. High praise from someone who grew up making treats the old fashioned way.
Finding Ube Ingredients
If youve never shopped at an Asian grocery store, this is your excuse to explore one. The ube halaya is usually in the Filipino section, and dont be afraid to ask someone working there if you cant find it. Theyll probably get excited that youre making something from their culture.
Making Them Vegan
Ive made these for my vegan sister using plant butter and vegan marshmallows, and honestly, theyre just as good. The ube carries so much flavor on its own that you wont miss anything. Just double check that your marshmallows are actually vegan because some sneak in gelatin.
Storage and Sharing
These will stay fresh in an airtight container for up to three days, but theyve never lasted that long in my house. If youre bringing them somewhere, pack them between layers of wax paper so they dont stick together.
- Wrap individual squares in plastic wrap for lunchbox treats that make coworkers jealous
- These freeze surprisingly well if you want to hide a stash for yourself
- The color actually stays vibrant for days, unlike some naturally colored foods that fade
These treats have become my go to for whenever I need to bring something that guarantees smiles. Theres something about that purple color that makes people feel like kids again.
