Ingredients

Scale
  • 1 cup (90g) rolled oats
  • 2 tablespoons (30g) chia seeds
  • 1½ cups (360ml) milk of choice (dairy, almond, oat, or preferred)
  • ½ cup (120g) Greek yogurt, plain or vanilla (optional but recommended)
  • 1 teaspoon vanilla extract
  • ½ teaspoon cinnamon
  • 12 tablespoons maple syrup or honey (adjust to taste)
  • 1 cup (150g) mixed berries (blueberries, raspberries, strawberries), fresh or frozen
  • 1 teaspoon lemon juice

Instructions

  1. Make the mixed berry chia jam: In a small bowl, combine 1 cup (150g) mixed berries with 1 tablespoon maple syrup or honey and 1 teaspoon fresh lemon juice. Mash gently with a fork until chunky and jam-like. Stir in 1 tablespoon (15g) chia seeds and set aside for at least 15 minutes to thicken. Optionally, warm berries gently in a saucepan over low heat for 3 minutes before adding chia seeds to speed thickening.
  2. Prepare the oats: In a medium bowl, mix 1 cup (90g) rolled oats, 2 tablespoons (30g) chia seeds, 1½ cups (360ml) milk of choice, ½ cup (120g) Greek yogurt, 1 teaspoon vanilla extract, ½ teaspoon cinnamon, and 1-2 tablespoons maple syrup or honey. Stir until well combined.
  3. Portion the oats evenly into 4 mason jars or containers (about ¾ cup or 180ml per jar), leaving space for the jam layer.
  4. Add the jam: Spoon 2-3 tablespoons of the thickened mixed berry chia jam on top of each jar. Optionally swirl the jam into the oats or keep layered.
  5. Seal and refrigerate overnight or for at least 6 hours to allow oats to soften and flavors to meld.
  6. Serve cold straight from the jar or warmed slightly in the microwave for 30-45 seconds. Optionally top with fresh berries, nuts, or nut butter.

Notes

Use rolled oats for best creamy texture; instant oats get mushy and steel-cut oats require longer soaking. Chia seeds thicken both jam and oats. Adjust sweetness with maple syrup or honey. Jam can be made ahead and stored separately. If oats are too thick in the morning, stir in a splash of milk. Layering jam keeps a pretty look; mixing jam creates uniform flavor. Refrigerate for 6-8 hours or up to 24 hours for convenience. Use milk with some fat content for creamier oats. Vegan substitutions include plant-based milk and yogurt, and maple syrup instead of honey.
