❓ Recipe questions + quick tips

What are the best plant-based milks for overnight oats?

Some of the best plant-based milks for overnight oats are almond milk, coconut milk, and oat milk, as they have a creamy texture and subtle flavors that complement the oats well.

How long should I soak the oats overnight for the best texture?

For the best texture, it is recommended to soak the oats in plant-based milk overnight for at least 4-6 hours or ideally up to 12 hours, as this allows the oats to absorb the liquid and soften to a creamy consistency.
