In a large bowl, whisk your oats, cacao powder, chia seeds, and sea salt.
Add in the brewed coffee, milk of your choice, maple syrup or honey, and vanilla.
Stir until well combined, then cover and refrigerate overnight or at least 6 hours.
In a small bowl, stir to combine the Greek yogurt with almond butter and protein powder until very smooth.
Refrigerate this mixture or use immediately.
Once you're ready to assemble the tiramisu oats, take 4 jars and divide the oats and yogurt equally layered as shown.
Finish with a layer of yogurt and sift cacao powder on the top.
These oatmeal jars stay well refrigerated in an airtight container for up to 3 days.
Enjoy!
