Moist, flavorful banana oat protein cups that are perfect for grab-and-go breakfasts, requiring no baking and minimal prep time.

Ingredients

Scale
  • 2 medium ripe bananas, mashed
  • 1½ cups (150g) old-fashioned rolled oats
  • ½ cup (50g) protein powder, vanilla or unflavored whey or plant-based
  • ¾ cup (180ml) milk, dairy or dairy-free (almond, oat, or cow’s milk)
  • ¼ cup (60g) Greek yogurt, plain or vanilla (can swap with coconut yogurt for dairy-free)
  • 1 tbsp chia seeds (optional)
  • 1 tsp ground cinnamon
  • 1 tsp baking powder
  • 1 tsp vanilla extract
  • Pinch of salt
  • Optional mix-ins: ¼ cup dark chocolate chips, chopped nuts, or dried fruit

Instructions

  1. Mash 2 ripe bananas with a fork until mostly smooth but still slightly chunky.
  2. Stir in ¾ cup milk, ¼ cup Greek yogurt, and 1 tsp vanilla extract into the mashed bananas; whisk gently to combine.
  3. In a separate bowl, mix 1½ cups oats, ½ cup protein powder, 1 tsp baking powder, 1 tsp ground cinnamon, 1 tbsp chia seeds (if using), and a pinch of salt.
  4. Pour the wet mixture into the dry ingredients and stir until just combined; avoid overmixing. Add a splash more milk if too thick.
  5. Fold in ¼ cup chocolate chips, nuts, or dried fruit if desired.
  6. Grease a 12-cup muffin tin or line with paper liners. Spoon batter evenly into each cup, filling about ¾ full.
  7. Cover the tin and refrigerate overnight (at least 6 hours) to allow oats to soften and flavors to blend.
  8. In the morning, serve cold or warm for 20-30 seconds in the microwave. Store leftovers in an airtight container in the fridge for up to 5 days or freeze for longer storage.

Notes

If cups seem too wet in the morning, microwave for 20-30 seconds to firm up. Let batter soak at least 6 hours for best texture. Baking at 350°F for 12-15 minutes is an option for a firmer muffin-like texture. Use ripe bananas with brown spots for natural sweetness. Adjust milk quantity if batter is too thick or thin. Protein powder choice affects texture and flavor.
