Ube Rice Krispie Treats

The first time I saw ube halaya at my local Asian market, I stood there staring at the vibrant purple jam like it held some kind of delicious secret. My kitchen still smelled like butter and sugar hours after making these treats, and my roommate texted me from work asking what kind of magic I was brewing. Now whenever I spot that distinctive purple jar, I know exactly what's happening in my kitchen that weekend.

I brought these to a potluck last spring and watched three different people ask for the recipe between bites. My friend Sarah, who claims she hates marshmallow treats, went back for seconds and then casually hovered near the platter until I packed her some to take home. Something about that purple hue makes people instantly curious, and one bite usually seals the deal.

Ingredients

• 6 cups crispy rice cereal: The foundation of that classic crunch we all remember from childhood lunchboxes
• 4 cups mini marshmallows: These melt faster and more evenly than the large ones, creating that perfectly gooey texture
• 1/4 cup unsalted butter: Provides richness and helps prevent the treats from becoming overly sweet
• 1/3 cup ube halaya: This purple yam jam is the soul of the recipe, bringing nutty, vanilla notes and that gorgeous color
• 1/2 teaspoon ube extract: Optional but worth it if you want deeper purple color and more intense flavor
• 2 tablespoons white chocolate chips: The creamy sweetness balances the earthy notes of ube perfectly
• 1 tablespoon toasted coconut flakes: Adds texture and a subtle tropical note that echoes ube's Filipino roots

Instructions

Prep your pan:

Butter a 9x9-inch pan thoroughly, getting into all the corners and up the sides, or your treats will stick stubbornly later

Melt the base:

Melt butter over low heat, then add marshmallows and stir patiently until completely smooth and no white lumps remain

Add the purple magic:

Stir in the ube halaya and extract until the mixture turns a mesmerizing shade of violet and becomes uniform throughout

Fold in the cereal:

Remove from heat immediately and gently fold in the cereal until every piece is coated, being careful not to crush the crispy bits

Press into the pan:

Transfer to your prepared pan and press firmly but gently with a greased spatula to create an even layer without compacting too tightly

Add the toppings:

Drizzle melted white chocolate across the top while still slightly warm, then scatter toasted coconut flakes for that finishing touch

Let them set:

Wait at least one hour at room temperature before cutting into squares, though I'll admit to sneaking a warm corner piece once or twice

My niece now requests these for every family gathering, and she has started calling them purple power treats. There's something about seeing that bright purple against a white plate that makes people smile before they even take a bite. Food that brings joy before it reaches your mouth is doing something right.

Finding Ube Ingredients

I've found ube halaya and extract at Filipino markets, Asian grocery stores, and even in the international aisle of well-stocked supermarkets. Online retailers carry them too, though shipping can take a few days. The first time I bought ube halaya, I accidentally grabbed the sweetened version meant for desserts, which actually worked out perfectly for this recipe.

Making It Vegan

When my vegan friend asked if I could make these plant-based, I discovered that vegan marshmallows and butter substitutes work surprisingly well. The texture stays just as chewy, and the ube flavor remains front and center. Just check your marshmallows carefully, as some contain gelatin despite being labeled vegetarian friendly.

Storage and Serving

These treats keep beautifully at room temperature for three days in an airtight container, though they rarely last that long in my house. I've also frozen them for up to a month between layers of parchment paper, thawing at room temperature when that purple craving hits.

• Cut them with a sharp knife that's been warmed under hot water for the cleanest squares
• If the white chocolate hardens too much for cutting, let the treats sit at room temperature for 15 minutes first
• Pack them in parchment paper layers for gift boxes or party favors to prevent sticking

Pin it

Every time I make these, I'm reminded that the best recipes often start with curiosity and a willingness to try something new. Purple marshmallow treats seemed strange at first, but now they're one of those recipes I can't imagine my kitchen without.

Recipe FAQ

→ What does ube taste like?

Ube has a subtle, nutty flavor with hints of vanilla and sweet potato. It's mildly sweet with a creamy texture that pairs perfectly with marshmallows and white chocolate.

→ Where can I buy ube halaya and extract?

Ube halaya (purple yam jam) and ube extract are available at most Asian grocery stores, Filipino markets, or online specialty retailers. Some well-stocked international aisles may also carry them.

→ Can I make these treats vegan?

Yes! Simply use vegan butter and vegan marshmallows (many brands use plant-based gelatin alternatives). The ube halaya is naturally vegan, making these bars easily adaptable for plant-based diets.

→ How should I store ube rice krispie treats?

Store in an airtight container at room temperature for up to 3 days. Avoid refrigeration as it can make the bars hard. If you need to keep them longer, individually wrap and freeze for up to 1 month.

→ Why is my mixture not turning purple?

The purple color comes primarily from the ube halaya jam. If your brand is lighter in color, add the optional ube extract to enhance the hue. Food coloring can also be used, though the natural purple from ube is usually sufficient.

→ Can I use regular marshmallows instead of mini?

Absolutely! Regular marshmallows work just as well—simply cut them into smaller pieces or allow extra melting time. Mini marshmallows melt slightly faster and more evenly, but both produce delicious results.
