# Instructions:

01 - Preheat your oven to 350°F. Line the bottom of three 8-inch round baking pans with parchment paper and set aside.
02 - In a large bowl, sift cake flour, baking powder, and salt.
03 - In a smaller bowl, combine ube extract, vegetable oil, and milk. Set aside.
04 - In a large bowl, beat egg yolks and gradually add ⅓ cup sugar (about a teaspoon at a time) using a handheld mixer until light yellow (about 7 minutes on medium-high speed).
05 - Add ube jam and mix until smooth with no lumps. Optionally, add gel food color for a vibrant purple and stir until evenly distributed.
06 - Fold a third of the dry ingredients into the egg mixture until combined. Add half of the wet ingredients, then alternate with dry and wet until fully combined without overmixing.
07 - Using a clean, grease-free mixer, beat egg whites until foamy. Add cream of tartar and beat until very frothy. Gradually add ¾ cup sugar and continue beating until stiff peaks form.
08 - Fold a cup of the meringue into the batter to lighten it. Then gently fold in the remaining meringue until well blended.
09 - Transfer the batter to prepared pans and bake for 20 minutes or until a toothpick inserted in the center comes out with minimal crumbs. Cool completely on a rack with pans upside down.
10 - Prepare Swiss meringue buttercream by beating egg whites and sugar over a simmering water bath until sugar dissolves. Whisk with a stand mixer until fluffy, then add butter gradually. Add ube extract until desired flavor and color is achieved.
11 - Trim uneven tops and brown edges of cooled cakes for a vibrant appearance. Fill and frost the cake layers with ube buttercream. Decorate as desired.

# Notes:

01 - Ube extract and jam are available in Asian markets or online. Adjust sugar levels based on the sweetness of the jam used.
