These eye-catching treats blend Filipino ube (purple yam) with classic American marshmallow crispy squares for a unique fusion dessert. The ube adds distinctive nutty, vanilla notes while creating a stunning vibrant purple color that stands out at any gathering.
Making these colorful bars takes just 20 minutes total time—simply melt butter with marshmallows, swirl in ube jam and extract, then coat crispy rice cereal. Press into a pan, let cool, and optionally finish with white chocolate drizzle and toasted coconut for extra flair.
The result is perfectly chewy squares with that satisfying crunch. They stay fresh for days in an airtight container and can easily be made vegan with plant-based marshmallows. Both kids and adults love the playful purple hue and unique tropical flavor profile.
The first time I saw ube anything was at my friend Liza's birthday potluck. Someone brought these impossibly purple squares that looked like they belonged in a fairy tale, not on a folding table. I took a hesitant bite, expecting artificial grape flavor, and instead got this nutty, vanilla sweetness that reminded me of roasted sweet potatoes my grandmother used to make. I went back for seconds and then thirds, not even caring that I was the last person at the dessert table.
Last summer my niece was having a rough week and I promised her we would make something ridiculous together. We stumbled upon ube halaya at the Asian market and she looked at me like I had three heads when I said we were making purple rice krispie treats. But as we stirred the marshmallows and watched the mixture turn that shocking violet, her eyes lit up. We made such a mess of the kitchen and I had ube smears on my shirt for two days, but seeing her proudly serve those bright squares to her parents was absolutely worth it.
Ingredients
- 6 cups crispy rice cereal: Use whatever brand you like but avoid the excessively sweet ones
- 4 cups mini marshmallows: Mini ones melt faster and more evenly than the big ones
- 1/4 cup unsalted butter: Salted butter works but unsalted lets the ube flavor shine through
- 1/3 cup ube halaya: This purple yam jam is what gives the treats their signature color and flavor
- 1/2 teaspoon ube extract: Optional but worth it if you want deeper purple color
- 2 tablespoons white chocolate chips: The contrast against the purple is stunning
- 1 tablespoon toasted coconut flakes: Adds nice texture and tropical flavor
Instructions
- Prep your pan:
- Grease a 9x9-inch baking pan thoroughly with butter or nonstick spray, getting into the corners
- Melt the base:
- Over low heat, melt butter in a large saucepan then add marshmallows, stirring until completely smooth
- Add the purple magic:
- Stir in ube halaya and extract until fully incorporated and the mixture turns vibrant purple
- Combine with cereal:
- Remove from heat and immediately fold in crispy rice cereal, stirring gently until evenly coated
- Press and set:
- Transfer to prepared pan and press firmly with a greased spatula or wax paper into an even layer
- Add the finishing touches:
- Drizzle melted white chocolate over the top and sprinkle with toasted coconut flakes if desired
- Cool completely:
- Let sit at room temperature for at least an hour before cutting into 16 squares
My roommate walked in while I was photographing these for a friend's recipe collection and demanded to know why I was serving purple plastic for dessert. After she tried one, she literally asked if I could make them for her wedding next year. These treats have this way of making people feel like kids again while introducing them to something completely new and delicious.
Making Them Your Own
Sometimes I fold in a handful of toasted macadamia nuts right at the end for crunch. Other times I skip the white chocolate drizzle entirely and just go for the coconut. The base recipe is so forgiving that you can really play around with toppings and mix ins without worrying about ruining the chemistry.
Serving Suggestions
These make an incredible addition to any potluck or party spread because they are completely unexpected. I have served them alongside traditional Filipino desserts and also next to classic chocolate chip cookies. They are conversation starters and usually the first thing to disappear, no matter what else is on the table.
Storage And Make Ahead Tips
I learned the hard way that these need to be stored in an airtight container or they turn into sad, stale rocks. Layer them between pieces of wax paper if you are stacking them. They actually stay fresh at room temperature for about three days, though they rarely last that long in my house.
- Make these up to two days before an event and they will still taste perfectly fresh
- Wrap individual squares in plastic wrap for easy party grabbing or lunchbox treats
- If you need to freeze them, separate layers with parchment paper and thaw at room temperature
There is something joyful about food that is this color and this fun to make. I hope these bright purple treats bring as much happiness to your kitchen as they have to mine.
Your Recipe Questions Answered
- → What does ube taste like?
-
Ube has a subtle nutty, vanilla-like flavor with hints of coconut. It's naturally sweet but not overpowering, making it perfect for desserts. The taste is often compared to sweet potato but more delicate and aromatic.
- → Where can I buy ube ingredients?
-
Ube halaya (purple yam jam) and ube extract are typically found in Asian grocery stores, Filipino markets, or international food aisles. Some well-stocked supermarkets carry them in their ethnic food section. Online retailers also offer these specialty ingredients.
- → Can I make these without ube extract?
-
Absolutely. The ube halaya jam provides plenty of purple color and flavor. Extract mainly deepens both aspects, so it's optional. Your treats will still be deliciously purple with just the jam incorporated.
- → How do I store these treats?
-
Keep squares in an airtight container at room temperature for up to 3 days. Place parchment paper between layers to prevent sticking. Avoid refrigeration as it makes them hard and less enjoyable.
- → Can I double this recipe?
-
Yes, simply use a larger 9x13-inch pan when doubling. The melting and mixing process remains the same, though you may need to work in slightly larger batches to coat all cereal evenly before it starts setting.
- → What makes these different from regular crispy treats?
-
The addition of ube transforms ordinary squares into something special with striking purple color and unique tropical flavor. Plus, the Filipino-American fusion creates an exciting twist on the nostalgic classic that guests will remember.
