A quick and easy healthy breakfast recipe featuring creamy overnight oats blended with protein powder, peanut butter, and ripe banana for a satisfying start to your day.

Ingredients

Scale
  • 1/2 cup (45g) rolled oats (old-fashioned)
  • 1 scoop (~30g) vanilla-flavored protein powder (whey or plant-based)
  • 2 tbsp (32g) natural peanut butter (no added sugar)
  • 1 medium ripe banana, mashed
  • 1 cup (240ml) milk of choice (dairy or plant-based)
  • 1 tbsp (12g) chia seeds (optional)
  • 1 tsp honey or maple syrup (optional)
  • 1/2 tsp vanilla extract
  • 1/4 tsp cinnamon (optional)

Instructions

  1. Mash the banana in a mixing bowl or jar until smooth but still a bit chunky (about 2 minutes).
  2. Stir in 2 tablespoons of natural peanut butter. Microwave for 10 seconds if peanut butter is stiff for easier mixing (about 1 minute).
  3. Add rolled oats, protein powder, chia seeds (if using), and cinnamon. Mix well to combine (1-2 minutes).
  4. Pour in milk and vanilla extract. Stir until evenly combined; mixture should be thick but pourable (1 minute).
  5. Taste and add honey or maple syrup if additional sweetness is desired (30 seconds).
  6. Cover the container with a lid or plastic wrap and refrigerate overnight or at least 6 hours.
  7. In the morning, stir the oats. Add a splash of milk if too thick. Serve topped with fresh banana slices, a drizzle of peanut butter, or chopped nuts if desired (2 minutes).

Notes

Use rolled oats for best creamy texture; quick oats may become mushy and steel-cut oats won’t soften enough overnight. Natural peanut butter may separate; stir well before measuring. Protein powder should be added to dry ingredients first to avoid clumps. Chia seeds are optional but add thickness and omega-3s. Refrigerate at least 6 hours, ideally 8-10 hours for creamiest results. Store leftovers up to 3 days in fridge; add milk before eating if thickened. Microwave for 30 seconds to warm without losing creaminess.
