Ube Halaya

Step 1
Place yams into a large pot and cover with water; bring to a boil. Reduce heat to medium-low and simmer until tender, about 20 minutes. Drain and cool until safe to handle, about 20 minutes. Grate yams into the pot.

Step 2
Add coconut milk, sweetened condensed milk, brown sugar, evaporated milk, butter, and vanilla extract to the pot over low heat. Cook, stirring constantly, until thick and sticky, about 20 minutes; mixture should be able to drop into room-temperature water and form a small ball when done.

Step 3
Transfer mixture into greased molds and chill until set, about 30 minutes.
