Place the diced mango and unsweetened coconut flakes in your food processor or blender. If you are using frozen mango, let it sit at room temperature for at least 20 minutes so it can thaw and blend smoothly.

Blend the mango and coconut together until completely smooth, creating a fragrant and thick puree. You can add the optional lemon or lime juice at this stage for a little extra brightness—I like adding a splash for a hint of tang.

Transfer the mango-coconut puree into a large bowl. Add the plain yogurt and stir gently with a spoon until everything is well combined and creamy.

Taste the finished yogurt mixture and add honey or maple syrup if you'd like it sweeter. Start with a small drizzle and add more to your liking. Serve chilled as a snack or breakfast.
