Notes

  • Use rolled oats for the best texture - quick oats soften more, while steel-cut oats stay too firm.
  • Full-fat or 2% Greek yogurt gives a richer, creamier result.
  • Add a few tablespoons of cottage cheese for even more protein.
  • Mash in a banana for natural sweetness and extra thickness.
  • Toast nuts before topping for a deeper, nuttier flavor.
  • If oats thicken too much, stir in 1–3 tablespoons of milk before serving.
  • Keep things interesting by rotating toppings like apples & walnuts or banana & peanut butter.
