Slice the peach. Heat a small pan over medium heat, add the butter and maple syrup, and once melted, add the peach slices. Cook for a couple of minutes until softened and lightly caramelised. Set aside.

In a bowl or jar, combine the oats, seeds, yogurt, maple syrup, and milk. Stir well to combine. Leave to set in the fridge for at least 1 hour, or overnight, until the mixture is thickened and the oats have absorbed the liquid.

Top the oat mixture with the caramelised peaches.
