These vibrant purple treats transform the classic crispy marshmallow bars with the addition of ube halaya (purple yam jam). The nutty, vanilla-like flavor of ube creates a uniquely delicious twist that's both visually striking and incredibly tasty. Ready in just 20 minutes with only 10 minutes of active preparation, these chewy bars are perfect for parties, potlucks, or whenever you want a fun, colorful dessert that bridges Filipino and American comfort food traditions.
The first time I brought these purple squares to a potluck, someone honestly asked if I'd dyed regular Rice Krispie treats with food coloring. I laughed and explained about ube, that Filipino purple yam with this incredible earthy vanilla flavor that's hard to describe until you taste it. Now friends specifically request them for birthdays because that vibrant color makes people happy before they even take a bite.
I made these for my niece's graduation party last spring alongside traditional Filipino desserts my aunt brought. Everyone gravitated toward the familiar rice cereal treats but then did this delighted doubletake at the flavor and color. Now they've become this bridge dessert in our family, something that feels like home to all of us.
Ingredients
- 6 cups crispy rice cereal: Use whatever brand you love, but avoid the overly sweetened varieties
- 4 cups mini marshmallows: Mini ones melt faster and more evenly than the big ones
- 1/4 cup unsalted butter: Unsalted lets you control the salt level since some marshmallows are already salty
- 1/3 cup ube halaya: This purple yam jam is what gives the treats their signature flavor and gorgeous color
- 1/2 teaspoon ube extract: Optional, but it deepens both the purple color and that distinctive vanilla like flavor
- White chocolate chips: A drizzle on top balances the earthy ube with something sweet and creamy
- Toasted coconut flakes: Adds texture and a tropical note that plays nicely with the ube
Instructions
- Prep your pan:
- Butter a 9x9 inch pan thoroughly, getting into all the corners
- Melt together:
- Melt butter over low heat, add marshmallows, stir until completely smooth
- Add the magic:
- Stir in ube halaya and extract until the mixture turns this stunning vibrant purple
- Coat the cereal:
- Fold in cereal gently, folding until every piece is evenly coated with that purple marshmallow goodness
- Press firmly:
- Transfer to your prepared pan, press down firmly with a greased spatula so they hold together
- Add toppings:
- Drizzle melted white chocolate on top, sprinkle with toasted coconut while warm
- Let them set:
- Cool completely for at least an hour before cutting into squares
My daughter now insists these are superior to regular Rice Krispie treats, which I honestly can't argue with. There's something about that earthy sweet ube flavor that makes them feel more special, like a treat from a fancy bakery instead of something you threw together in twenty minutes.
Getting That Perfect Purple
The color intensity depends entirely on your ube halaya brand. Some batches turn this soft lavender, others go nearly electric purple. Don't stress about it either way, they'll taste amazing regardless of what shade you end up with.
Storage Secrets
These actually stay soft and chewy longer than regular versions thanks to the extra moisture from the ube halaya. I've kept them for four days in an airtight container and they were still perfect, though in my house they rarely last that long.
Serving Ideas
Cut them slightly smaller than you think you should because they're rich and people tend to grab multiple when they see that color. They're stunning on a dessert table alongside coconut macaroons or mango bars for a Filipino inspired spread.
- Wrap individual squares in parchment paper for party favors or bake sales
- Try cutting them into fun shapes with cookie cutters while they're still slightly warm
- These freeze beautifully, just layer between wax paper in an airtight container
Every time I make these now, I think about how something so simple can feel so celebratory. That shock of purple on the plate just makes people smile.
Recipe FAQs
- → What does ube taste like?
-
Ube has a subtle, nutty flavor with hints of vanilla and sweet potato. It's mildly sweet with a pleasant earthiness that pairs beautifully with the marshmallows and buttery rice cereal in these bars.
- → Where can I buy ube halaya and extract?
-
Look for ube halaya (purple yam jam) and ube extract at Asian grocery stores, particularly Filipino markets. Many well-stocked international food aisles also carry these items. You can also find them online through specialty retailers.
- → Can I make these treats vegan?
-
Yes! Simply substitute vegan butter and vegan marshmallows for the traditional dairy versions. The ube halaya is naturally plant-based, making these treats easily adaptable for vegan diets while maintaining their signature purple color and flavor.
- → How should I store ube rice crispy treats?
-
Store the bars in an airtight container at room temperature for up to 3 days. Keep them away from direct sunlight and heat to prevent melting. The treats will remain chewy and fresh, though the purple color may fade slightly over time.
- → Why are my treats hard instead of chewy?
-
Hard treats usually result from overheating the marshmallow mixture or pressing too firmly when shaping. Always melt marshmallows over low heat and stir gently. When transferring to the pan, use light, even pressure rather than pressing down firmly to maintain the perfect chewy texture.
- → Can I add other toppings besides white chocolate and coconut?
-
Absolutely! Try sprinkling colorful nonpareils, crushed graham crackers, chopped nuts, or even additional ube halaya swirled on top. The white chocolate and coconut complement the ube flavor nicely, but these bars are versatile and work with various toppings.
