How to make Ube Cake Roll

For the filling, use purple yam spread, AKA ube halaya

For the cake batter, whip the egg whites with sugar until firm

Then, beat the yolks with sugar until pale and creamy

Combine flour with the beaten yolks and whipped whites into a fluffy batter

Pour the cake batter in a lined tray and tap it to remove air bubbles

Bake the cake until spongy, flip it on a sheet of paper, and peel off the paper on top

Spread the ube filling evenly over the sponge cake

Starting at the short side, roll the cake around the filling into a log

Let the ube roll set in the fridge for 30 minutes, slice it, and serve!
