What Makes Ube SuperFood Powder Different?

If you’ve seen regular ube powder at the store and wondered if it’s the same thing: it’s not, and the difference really does matter. Here’s why I always reach for my Ube SuperFood Powder over plain ube powder.

It’s Not Just Ube – It’s a Collagen Boost

Regular ube powder gives you flavor and color. My Ube SuperFood Powder does that and delivers a boost of collagen so it supports skin, hair, nails, and joint health. So your single serve afternoon cookie is officially doing double duty. You’re welcome.

Vibrant Color Without the Mess

Just one tablespoon of my Ube SuperFood Powder gives you a rich, deep purple cookie that looks straight out of a dream. Combined with the ube flavoring paste, the result is something that looks as stunning as it tastes, no wrestling with fresh ube root, no tracking down frozen ube halaya, no fuss.

Easy to Measure, Easy to Use

For small-batch baking like this single serve recipe, precision matters. The powder format means you measure exactly what you need: no waste, no opening a whole can of ube jam for one cookie. It incorporates seamlessly into the dough and plays beautifully alongside the ube flavoring paste for a layered, true-to-ube flavor that plain ube powder just can’t match.

Here’s what you’ll need to make this beauty. Full measurements are in the recipe card below!

Key Ingredients

Butter – barely melted keeps the cookie tender and chewy rather than greasy or flat.
Brown sugar + granulated sugar – the combination gives you that perfect chewy-centered, slightly crisp-edged cookie.
Egg yolk – just the yolk adds richness and structure without making a single-serve portion cakey.
Ube SuperFood Powder – one tablespoon brings the color, the ube flavor, and the collagen benefits. The star of the show.
Ube flavoring paste – the secret to deep, authentic ube flavor. A little goes a long way! Fair warning: it will stain your hands and clothes, so handle with care.
Vanilla paste – adds warmth and depth that plays beautifully with the ube.
Cream of tartar – don’t skip this one! It keeps the pH in check so your cookie stays a gorgeous, vibrant purple as it bakes rather than turning green.
White chocolate chips – the creamy sweetness is the perfect complement to earthy, slightly sweet ube.
Macadamia nuts – optional but highly recommended for that buttery crunch.
Flaky sea salt – always. Non-negotiable. It makes every bite sing.

This comes together in one bowl in about five minutes, then it’s all about the oven.

Preheat your oven to 350°F and line a small baking sheet with parchment paper. Set aside.
Combine butter and both sugars in a small bowl, stirring until well combined.
Add the egg yolk, Ube SuperFood Powder, vanilla paste, and ube flavoring paste. Switch to a small rubber spatula and whip everything together until smooth and beautifully purple.
Sprinkle the flour, baking powder, cream of tartar, and salt over the wet ingredients. Stir to combine well, then fold in the white chocolate chips and macadamia nuts if using. I like to use my hands here, but I do put on a plastic prep glove since that ube flavoring is very PURPLE and can stain your hands.
Divide the dough into two equal portions and place on your prepared baking sheet about 2–3 inches apart. Or keep it as one glorious large cookie – entirely your call.
Bake for 12–14 minutes, until the edges just begin to set. The center will look underdone – that’s exactly right.
Right out of the oven, press a few extra white chocolate chips on top and finish with a generous pinch of flaky sea salt. Allow to cool 5–7 minutes to fully set, then grab that book and enjoy!

Don’t Overbake

The edges should just barely be set when you pull these from the oven – they’ll continue firming up as they cool on the pan. Resist the urge to leave them in for “just one more minute.” Overbaked means dry, and we are absolutely not doing that.

The Cream of Tartar Is Not Optional

Ube has a quirky chemistry – it can turn green when exposed to heat in an alkaline environment. The cream of tartar keeps the pH in check and ensures your cookie stays that stunning, vibrant purple all the way through the bake. Don’t skip it!

The Flaky Salt Is Your Friend

That final sprinkle isn’t just decorative – it balances the sweetness of the white chocolate and makes every bite more complex and satisfying. It’s the finishing touch that takes this from good to great.

Go Gluten-Free If You Need To

This recipe works beautifully with a 1:1 gluten-free flour substitute, like Caputo gluten free flour. The small batch size makes it a great recipe to test a new GF blend with — low risk, high reward.

A Note on Ube Flavoring

A quick note on ube flavoring: I use it in this recipe and it does add a lovely boost of color and a more pronounced ube flavor. That said, I want to be upfront that ube flavoring is not a natural product. It contains artificial red and blue colorings, which some people have sensitivities or reactions to. If that is a concern for you, simply leave it out! My Ube Superfood Powder carries plenty of gorgeous natural color and real ube flavor on its own and your cookies will still be absolutely stunning.

Ingredients

2 tbsp butter, barely melted
2 ½ tbsp brown sugar
1 ½ tbsp granulated sugar
1 egg yolk
1 tbsp ube superfood powder
½ tsp vanilla paste
¼-½ tsp ube flavoring paste
⅓ cup flour, sub your fav g/f flour 1:1 as needed
⅛ tsp baking powder
⅛ tsp cream of tartar, to keep the cookie from turning green as it bakes
Pinch of vanilla salt
2-3 tbsp white chocolate chips
1-2 tbsp macadamia nuts, roughly chopped, optional
Flaky sea salt

Directions

Preheat your oven to 350° and line a small baking sheet with parchment paper, set aside.
Stir together butter and both sugars until well combined with a small whisk in a bowl. Add the egg yolk, ube superfood powder, vanilla paste and ube flavoring/paste. With a small rubber spatula, whip until well combined. Careful with the ube paste, it can stain your hands and clothes!
Sprinkle the flour, baking powder, cream of tartar and salt on top of the wet ingredients, stir to combine well. Add white chips and macadamia nuts (if using) and stir to combine.
Divide dough into two equal portions* and place each dough ball on the prepared baking sheet about 2-3” apart. Place in the oven and bake for 12-14 minutes or until edges just begin to get slightly set.
Remove from the oven, immediately place a few more chocolate chips on top if desired to create more visual white pops of color and sprinkle with flaky salt. Allow to cool for 5-7 minutes to fully set, then grab that book and enjoy!

Notes

TO FREEZE: simply place muffins on a cooling rack in the freezer then once they’re individually frozen, place them in a freezer safe zipper bag. Store for up to 3 months. When ready to enjoy, remove from the freezer and allow to come to room temperature or microwave for around 35-40 secs.
For one large personal cookie, skip dividing and bake the full dough portion as one ball. Add 1–2 minutes to the bake time and keep an eye on the edges.

Frequently Asked Questions

Can I double this recipe?

Absolutely! This recipe scales up easily, just double or triple the ingredients and bake in batches. That said, the single-serve size is a big part of the charm here. Sometimes one perfect cookie is all you need.

Can I skip the macadamia nuts?

Yes! They’re optional. The cookie is completely delicious without them. You could also swap in a few chopped cashews or just let the white chocolate be the only mix-in, both are great.

Where can I find ube flavoring paste?

The most common brand I see used is Butterfly Ube Flavor, I found mine on Amazon. Many Asian supermarkets may also carry it, but be sure to check the ingredients for actual ube and not just sugar and water with some food coloring. A little goes a long way, so a small bottle will last you many, many batches!

How do I store leftovers?

If you somehow have leftovers, store them in an airtight container at room temperature for up to 2 days. But honestly? That’s not going to be a problem.
