In a mason jar or container, add the Greek yogurt, almond milk, and honey. Stir together until the honey is fully dissolved and the mixture is smooth—this ensures even sweetness throughout. The yogurt adds creaminess and protein while the milk creates the liquid base that the oats and chia seeds will absorb overnight. Pour in the rolled oats and chia seeds, stirring well to combine and prevent clumping.
Sprinkle the cinnamon (I prefer freshly ground for a warmer, more vibrant flavor) and hemp hearts over the oat mixture and stir thoroughly to distribute evenly. Cover the jar tightly with a lid or plastic wrap—this prevents the mixture from drying out and keeps any odors from the refrigerator at bay. Place in the refrigerator and let sit overnight, or at least 6-8 hours. The oats and chia seeds will absorb the liquid and create a creamy, pudding-like consistency.
Remove the overnight oats from the refrigerator in the morning. If the consistency is too thick, stir in a splash of additional almond milk to reach your desired creaminess. Top with fresh fruit of your choice—berries, sliced banana, or diced apple all work beautifully—and enjoy straight from the jar or transfer to a bowl. I like to add a drizzle of honey on top for extra sweetness and a nice visual touch.
