I like to use canned full-fat coconut milk for the best flavor and creamy texture, though you can use "light" coconut milk if that's what you can find at your store.
Add all ingredients to a medium bowl except the toppers. Stir together to make a smooth mixture.
Add to airtight containers (I like to do small snack-size ones but you can do one larger container too) and store in the fridge for at least 2 hours and up to 3-5 days.
Serve cold topped with desired toppings.

Notes
Store in the fridge in airtight containers for up to 3-5 days.
Dairy-free: Use nondairy Greek-style yogurt.
Use canned coconut milk for the best coconut flavor.
Use regular milk if you're not into coconut.
You can make this a little smoother by blending the mixture up in a blender before popping it into the fridge or using ground chia seeds.
If your yogurt is lumpy and not stirring up well, use a whisk to make a smooth mixture.
Top with fresh fruit, granola, or other desired toppers.
