1. Prepare the Cake Batter:

1. Preheat your oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment paper.

2. In a large mixing bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.

3. In another bowl, beat the sugar and oil (or butter) until combined. Add the eggs one at a time, mixing well after each addition.

4. Mix in the ube halaya, ube extract, and vanilla extract until smooth.

5. Gradually alternate adding the dry ingredients and milk to the wet mixture, beginning and ending with the dry ingredients. Mix until just combined.

2. Bake the Cake:

1. Divide the batter evenly between the prepared cake pans.

2. Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.

3. Allow the cakes to cool in the pans for 10 minutes before transferring to a wire rack to cool completely.

3. Prepare the Frosting:

1. Beat the softened butter in a large bowl until creamy.

2. Gradually add the powdered sugar, one cup at a time, mixing well after each addition.

3. Mix in the heavy cream and ube extract, and beat until the frosting is light and fluffy.

4. Assemble the Cake:

1. Level the tops of the cakes if needed. Place one layer on a serving plate and spread a generous amount of frosting on top.

2. Add the second cake layer and frost the top and sides.

3. Decorate with piped frosting, edible flowers, or a sprinkle of toasted coconut for a finished look.

5. Serve and Enjoy:

Slice and serve your vibrant ube cake for a stunning and delicious dessert.
