  • Whisk
  • Rubber spatula
  • Measuring cups and spoons
  • Toothpick or skewer (for swirling & doneness test)
  • Cooling rack

Ingredients

Banana Bread Batter

  • 3 ripe bananas mashed
  • ½ cup unsalted butter melted
  • ¾ cup brown sugar
  • ¼ cup granulated sugar
  • 2 large eggs room temperature
  • 1 tsp vanilla extract
  • 1½ cups all-purpose flour
  • 1 tsp baking soda
  • ½ tsp salt
  • ½ tsp cinnamon optional

Ube Swirl

  • ā…“ cup ube halaya ube jam
  • 2 tbsp heavy cream or coconut milk
  • 1 tbsp sugar optional, if ube isn’t sweet
  • ½ tsp ube extract optional, for color & aroma

Instructions

  • Preheat oven to 350°F (175°C). Grease and line loaf pan with parchment.
  • In a large bowl, whisk melted butter, brown sugar, and granulated sugar until glossy.
  • Add eggs, vanilla, and mashed bananas. Mix until smooth.
  • Fold in flour, baking soda, salt, and cinnamon just until combined.
  • In a small bowl, mix ube halaya, cream, sugar (if needed), and ube extract until smooth and spreadable.
  • Pour ā…” of banana batter into the pan.
  • Spoon ube mixture in ribbons over the batter.
  • Add remaining banana batter on top.
  • Swirl gently with a toothpick—do not overmix.
  • Bake 55–65 minutes, until a toothpick comes out mostly clean.
  • Cool 15 minutes in pan, then transfer to a rack.

Notes

  • Use very ripe bananas with heavy brown spotting for the sweetest flavor and moistest crumb.
  • Do not over-swirl the ube mixture—2–3 gentle passes with a toothpick creates a defined purple ribbon.
  • If your ube halaya is very thick, warm it slightly or add an extra teaspoon of coconut milk to make it swirlable.
  • Ube extract is optional but recommended for a deeper purple color and stronger vanilla-like aroma.
  • Tent loosely with foil if the top browns too quickly during the final 10–15 minutes of baking.
  • Let the loaf cool at least 15 minutes before slicing to set the crumb and preserve the swirl.
  • Flavor improves after resting—this bread tastes even better the next day.
  • Store tightly wrapped at room temperature for 2 days, refrigerate up to 5 days, or freeze for 3 months.

ā“ Frequently Asked Questions

What does ube taste like in banana bread?

Ube has a mild, sweet flavor similar to vanilla with subtle nutty and coconut notes. In banana bread, it adds richness without overpowering the banana.


Can I use ube powder instead of ube halaya?

Yes, but it must be rehydrated. Mix ube powder with warm milk or coconut milk until thick and smooth before swirling it into the batter.


Is ube the same as purple yam?

Ube is a type of purple yam, but it’s sweeter and more aromatic than standard purple sweet potatoes. For best results, use products specifically labeled ā€œube.ā€


Why did my ube swirl sink to the bottom?

If the ube mixture is too thin, it can sink. Make sure it’s thick and jam-like before swirling, or lightly layer it between batters.


Can I reduce the sugar in this recipe?

Yes. You can reduce the total sugar by up to ¼ cup without affecting structure, especially if your bananas are very ripe.


Can I make this recipe vegan?

Yes. Replace eggs with flax eggs, use vegan butter or coconut oil, and choose coconut milk for the ube swirl.


Does this bread need refrigeration?

Not immediately. It keeps well at room temperature for two days, but refrigeration is best for longer storage due to the ube filling.
