Ingrédients
  

  • 1 cup rolled oats old-fashioned oats
  • 1 cup unsweetened almond milk or milk of choice
  • 1/2 cup plain Greek yogurt 0% or full-fat
  • 1 medium apple diced (about 1 cup)
  • 1 tablespoon chia seeds
  • 1 tablespoon pure maple syrup or honey
  • 1 teaspoon ground cinnamon
  • Pinch of sea salt
  • Optional: 1/4 teaspoon vanilla extract

Equipment

  • Mason jars or airtight containers with lids
  • Medium mixing bowl
  • Measuring cups and spoons
  • Knife and cutting board
  • Whisk or spoon for mixing

Method
 

  1. Mix the base: In a medium bowl, whisk together almond milk, Greek yogurt, chia seeds, maple syrup, cinnamon, vanilla (if using), and salt until smooth and well combined.
  2. Add oats: Stir in rolled oats until evenly mixed with no clumps. The chia seeds will naturally thicken the mixture as it sits.
  3. Fold in apple: Gently stir in diced apple until evenly distributed throughout the mixture.
  4. Refrigerate: Divide the mixture evenly between two mason jars or containers, cover tightly with lids, and refrigerate for at least 4 hours or overnight. The oats will absorb the liquid and become creamy and thick.
  5. Serve: In the morning, give the oats a good stir. Top with extra fresh apple slices, chopped walnuts, a drizzle of nut butter, or a sprinkle of cinnamon as desired.

Notes

Substitute almond milk with oat milk, soy milk, or dairy milk for different flavor profiles.
Add a handful of chopped walnuts or pecans for satisfying crunch and heart-healthy omega-3 fatty acids.
Stir in vanilla or apple cinnamon-flavored protein powder to boost the protein content even higher.
Layer with fresh berries like blueberries or strawberries for added antioxidants and color.
Use grated apple instead of diced for a more integrated apple pie flavor throughout.
Make a larger batch in one big bowl and portion out servings each morning for ultimate flexibility.
Add a tablespoon of almond butter or peanut butter for extra protein and healthy fats.
