Equipment

  • 9x5 loaf pan

Ingredients

For the dough

  • 2 ½ cups 320g all-purpose flour (plus more as needed)
  • 1 cup 180ml warm milk (100–110°F)
  • 2 ½ tsp dry active Yeast
  • 1 tsp sugar
  • ¼ cup condensed milk
  • ½ tsp salt
  • 2 tbsp unsalted butter softened
  • 1 cup mashed purple sweet potato roasted or steamed, cooled
  • 1 egg

For the condensed milk glaze (optionally)

  • ¼ cup condensed milk
  • 1 tbsp butter melted
  • Optional: Pinch of salt or splash of vanilla

Instructions

Activate Yeast

  • Mix 1/4 cup warm milk and sugar, and sprinkle in the Yeast. Let it sit for 5–10 minutes until foamy.

Prepare the Doughs

  • Base Dough: In a bowl, mix flour, condensed milk, salt, Yeast mixture, egg, butter, and the rest of the warm milk. Knead until it comes together.
  • After the dough forms, split it in half.
  • To one half, knead in 1 cup of mashed purple sweet potato until fully incorporated.
  • Leave the other half as-is.
  • Knead both doughs until smooth and elastic — about 8–10 minutes.

First Rise

  • Place both dough balls in greased bowls. Cover and let rise in a warm spot until doubled — about 1–1.5 hours.

Create the Marble Effect

  • Lightly flour your work surface.
  • Roll each dough out into similarly sized rectangles.
  • Stack one on top of the other. Gently press together.
  • Roll the stacked dough into a large rectangle.
  • Fold it like a letter (tri-fold), then roll it out again. Repeat once or twice more to create soft swirls.
  • Finally, roll into a log, jelly-roll style.
  • Cut the dough into three pieces and twist them into a braided shape.

Second Rise

  • Place your rolled dough in a greased 9x5 loaf pan. Cover and let rise for 30–45 minutes until puffy.

Bake

  • Preheat oven to 350°F (175°C).
  • Bake for 30–35 minutes, until golden on top and cooked through.
  • To achieve a vibrant purple color, lightly cover it with foil during cooking, then remove the foil a few minutes before it's finished for the best results.

Condensed Milk Glaze (Optional but Heavenly)

  • Mix condensed milk and butter, then warm them for a few minutes.
  • While it's still warm, generously brush the top with a mix for an irresistible finish.
  • Optional: a tiny pinch of salt for contrast.

Cool & Slice

  • Let the bread cool before slicing to reveal those beautiful marbled swirls.
