In a medium bowl, whisk together the skyr, collagen peptides, vanilla, and sea salt until completely smooth.
Fold in the chia seeds and rolled oats, ensuring everything is evenly distributed to prevent clumping.
Cover the bowl and refrigerate for at least 2 hours, or ideally overnight, until the mixture transforms into a thick, creamy pudding.
When ready to serve, core and dice the apple into uniform half-inch cubes.
Melt the ghee in a small skillet over medium heat, then toss in the apples, cinnamon, and maple syrup.
Sauté for 3 to 5 minutes until the apples are tender and coated in a fragrant, golden glaze.
Give the pudding a quick stir to loosen the texture, then top with the warm cinnamon apples and enjoy immediately.
