Instructions

Preheat the oven to 350°F (175°C) and grease a 9×13-inch baking dish.
In a large bowl, whisk together mochiko flour, sugar, baking powder, and salt.
In a separate bowl, beat the eggs and mix in evaporated milk, coconut milk, melted butter, and vanilla extract.
Stir in the ube halaya or extract until the mixture is evenly purple.
Gradually add the wet ingredients to the dry ingredients, stirring until smooth and lump-free.
Pour the batter into the prepared baking dish and tap gently to remove air bubbles.
Sprinkle sesame seeds on top, if using.
Bake for 60 minutes, or until edges are golden and a toothpick inserted comes out clean.
Let the mochi cool completely before slicing into squares.

Notes

Let the mochi cool fully to firm up before slicing.

Store at room temperature for up to 2 days or refrigerate for up to 5 days.

Warm refrigerated mochi in the microwave for 10–15 seconds to soften.

Do not freeze, as texture may become grainy.

Swap ube halaya with extract for deeper color or convenience.

Add shredded coconut, toasted coconut flakes, or chopped macadamia nuts for variation.
