Ingredients

Scale
  • 1 cup old-fashioned rolled oats (90g)
  • 2 medium ripe bananas, mashed
  • 1/2 cup Greek yogurt (120g), plain or vanilla
  • 1/2 cup milk (120ml), any kind (dairy or plant-based)
  • 3 tablespoons brown sugar, packed
  • 2 tablespoons unsalted butter
  • 2 tablespoons dark rum (optional but recommended)
  • 1 teaspoon ground cinnamon
  • 1 teaspoon vanilla extract
  • Pinch of salt
  • 1/4 cup chopped pecans or walnuts, toasted (optional)

Instructions

  1. Mash 2 ripe bananas in a medium bowl with a fork until smooth but slightly chunky (about 2 minutes).
  2. Add 1 cup rolled oats, 1/2 cup Greek yogurt, 1/2 cup milk, 1 teaspoon vanilla extract, 1 teaspoon ground cinnamon, and a pinch of salt to the mashed bananas. Stir until well combined (about 3 minutes).
  3. In a small saucepan over medium heat, melt 2 tablespoons unsalted butter. Stir in 3 tablespoons brown sugar and let it melt and bubble gently for 2-3 minutes, stirring constantly to avoid burning.
  4. Carefully add 2 tablespoons dark rum while stirring (beware of flare-ups). Simmer for another minute until the sauce thickens slightly.
  5. Remove the caramel from heat and let it cool for 5 minutes until thick but still pourable.
  6. Pour half of the caramel sauce into the oats mixture and gently fold it in. Reserve the other half for topping when serving.
  7. Transfer the oats mixture into 2-3 glass jars or airtight containers. Seal tightly and refrigerate for at least 6 hours or overnight.
  8. Before serving, stir the oats gently. Drizzle the remaining warm caramel sauce on top and add chopped toasted pecans or walnuts if desired. Optionally, garnish with fresh banana slices or a sprinkle of cinnamon.

Notes

Keep a close eye on the caramel to prevent burning and stir constantly. Use ripe bananas for natural sweetness and creaminess. If caramel hardens in the fridge, warm it slightly before drizzling. Rolled oats are preferred for best texture; instant oats may become mushy. For dairy-free or vegan versions, substitute coconut yogurt, plant milk, coconut oil, and rum extract.
