Ingredients

Scale

Base Ingredients

  • 1 1/4 cups old-fashioned rolled oats
  • 1 cup Greek yogurt (plain, 2% or 0%)
  • 1 cup milk of choice (dairy, oat, almond, etc.)
  • 23 tbsp maple syrup or honey (adjust to taste)
  • 1 tsp vanilla extract
  • 1/2 tsp ground cinnamon
  • Pinch of salt

Protein and Extras

  • 1 scoop protein powder (optional, for extra protein)
  • 12 tbsp seeds or flaxseed (adds protein and fiber)
  • 1/2 cup fresh or frozen berries
  • 23 tbsp nuts or nut butter for extra protein and healthy fat

Instructions

  1. Mix Wet Ingredients: Add the Greek yogurt, milk, maple syrup (or honey), and vanilla extract in a large Tupperware and mix until combined thoroughly. This forms the creamy base for the oats.
  2. Add Dry Ingredients: Add in the rolled oats, salt, and ground cinnamon to the wet mixture and whisk again to ensure an even distribution of flavors and ingredients.
  3. Incorporate Protein Powder or Seeds: Stir in the protein powder or chia/flax seeds if using, to boost the protein and fiber content of the oats.
  4. Fold in Berries and Nuts: Gently fold in the berries and nuts or nut butter as desired to add texture, flavor, and additional nutrition.
  5. Refrigerate: Cover the container tightly and refrigerate the mixture for at least 6–8 hours or preferably overnight to allow the oats to soak and flavors to meld.
  6. Serve: Stir the oats before eating and top with extra fresh fruit, nut butter, or a sprinkle of cinnamon if you like for added flavor and garnish.
