A Yellow-and-Purple Merienda

To share my happiness with my DDI family, I thought of having a simple but yellow-and-purple merienda this afternoon. Can you guess what yummy food I bought?
A big thank you to our resident photographer, Wacky Salazar, for these awesome photos of butter macaroons (yellow) and an ube cake (purple) from Goldilocks. Here are more snapshots of our little celebration.

I wonder what our merienda will be for next quarter's royalty check. Any suggestions for fun yellow-and-purple food?
