🥛 What Are Overnight Oats?

Overnight oats are simply rolled oats soaked in milk (and sometimes yogurt) overnight. As they rest, the oats absorb the liquid and become thick, creamy, and pudding-like — no cooking needed! It’s a cool, refreshing breakfast that’s perfect for busy mornings or warmer weather.

In this version, mashed banana adds natural sweetness and a soft, silky texture that makes the oats taste like dessert for breakfast.

🍌 Ingredients You’ll Need

To make these high protein peanut butter banana overnight oats, you’ll need just a few pantry staples:

• 1 ripe banana – Naturally sweet and gives that banana bread flavor.
• 1¼ cups milk of choice – Almond milk, oat milk, or dairy milk all work great.
• 1 single-serve vanilla Greek yogurt (or plant-based) – Adds protein and creaminess.
• 1 cup rolled oats – Use gluten-free oats if needed.
• ½ tsp cinnamon – For that warm banana bread flavor.
• 1 tbsp chia seeds – Adds texture, fiber, and helps thicken the oats.
• 2 tbsp creamy peanut butter – For richness, protein, and flavor.

Optional toppings: sliced banana, crushed peanuts, a drizzle of extra peanut butter, or even a sprinkle of mini chocolate chips.
