9. Then add the liquid mixture while continuing to stir until well blended.
10. Pour the batter evenly into the prepared pan and smooth the top of the batter with a spatula.
11. Bake for 25 minutes or until a toothpick inserted into the batter comes out clean.
12. Remove cake from the oven and let it stand for 10 minutes.
13. Get a new piece of parchment paper that is slightly bigger than the cake.
14. Place the parchment paper on a flat surface then lightly dust the surface with powdered sugar.
15. Carefully turn the cake over onto the parchment paper.
16. Slowly peel off the parchment paper that the cake was cooked on.
17. Now get another piece of parchment paper that is slightly bigger than the cake.
18. Lightly dust the top of the cake with powdered sugar then place the second piece of parchment paper on top of the cake.
19. Now using the bottom piece of parchment paper, carefully roll the cake into a spiral cylinder shape.
20. Set the cake on a cooling rack to rest until it is cool enough to be comfortably handled.
21. When the cake has sufficiently cooled, unroll it so that it is flat again and discard the top piece of parchment paper
22. Spread the ube filling evenly on top of the cake then use the bottom piece of parchment paper to slowly roll the cake into a spiral cylinder shape again.
23. Place the rolled cake on a cake tray.
24. Cut off a thin slice from both ends of the cake roll.
25. Put the ube buttercream in a piping bag and apply it to the surface of the cake.
26. Spread the buttercream frosting over the entire surface of the cake.
27. Then decorate as desired; sprinkle with purple-colored sprinkles or top with a cherry.
28. Refrigerate before slicing.
29. Serve and enjoy!

Remember to not roll the parchment paper inside the cake. You just use the parchment paper to roll the cake into a spiral shape from the outside of the cake. If you are doing all this by hand, without an electric mixer, you may need someone to assist you at times. You can also add macapuno in your ube filling for extra flavoring if you'd like.
