In a medium, heavy saucepan, melt butter. Add coconut & condensed milks; stir until heated. Add thawed, grated ube & combine well.Cook over a low heat. It is important to stir the mixture often during cooking to prevent it from forming a ‘crust’. This process takes about 40-50 minutes until the ube is cooked. The mixture should be thick & sticky. Transfer the ube jam to a container & set aside.

In a small dish, heat milk to lukewarm. Add yeast & 1 tsp sugar; let sit for 5 minutes to allow yeast to activate. In a large bowl, whisk together remaining 1/4 cup sugar, melted butter, sour cream & egg. Add yeast mixture & stir to combine.
In another bowl, whisk flour & salt. Add flour mixture to yeast mixture one cup at a time, combining after each addition. Once all the flour has been added, knead on a lightly floured surface for about 2 minutes.
Lightly grease the large bowl, place dough in it & cover with plastic wrap & a tea towel. Allow to rest for at least one hour, in a draft-free place until dough has doubled in volume.
Lightly grease cups of either a popover or muffin tin. Sprinkle work surface with flour. Roll dough out into a rectangle 21 X 16-inches (about 54 X 40 cm). WITHOUT CUTTING through, mark dough into six equal strips starting on the longest side.
Thinly spread ube jam on strip # 2 & #5 (numbering from the left side). Fold strip #1 & #6 over the jam. Lightly spread the top of each folded side with more jam then fold each one toward center.
Now spread the top of one folded piece, then bring the other side over it. With a rolling pin, slightly press entire layered roll flatter.
With a buttered, sharp knife, cut the strip along its entire length into 3 strips. Next cut each strip horizontally into 4 (or 5) pieces. Carefully lift each piece, stretch it out a bit & then twist it.
Form it into a ring & place in muffin (or popover) cup. When all cruffins are in the pan, use a pastry tube & pipe some ube jam in center of the spiral.
Allow cruffins to sit in a draft-free place for about 30 minutes. Preheat oven to 350 F. Bake cruffins for 20-25 minutes. Grate cheese & set aside.
When cruffins are baked, remove from the oven. While still warm, sprinkle with grated cheese.
Recipe Notes
Instead of piping ube jam in center of unbaked cruffins, you can reserve any extra for serving on the side instead.
Instead of making a ‘true’ croissant dough, I used my favorite (sweet) yeast dough. Of course, you don’t get the flakiness of a croissant, but the taste & tenderness of the cruffin was still real good.
Another alternative would be to use frozen puff pastry.
