In a clean, airtight container, combine the ube halaya or ube extract with the coconut milk, plant milk, chia seeds, sweetener, and vanilla extract. Stir thoroughly until the mixture is smooth and evenly blended, creating a vibrant purple base.

Add the old-fashioned rolled oats to the ube mixture, gently folding them in until every oat is well-coated.

Cover the container tightly with its lid and place it in the refrigerator for at least 6 hours or overnight.

When morning arrives, give the oats a good stir. If the mixture appears thick, add a splash of additional plant milk to achieve your desired creaminess. Garnish with your favorite toppings like fresh fruits, nuts, or a drizzle of nut butter.
