Measure your base: Add 1/2 cup rolled oats, 1/2 cup milk, and 1/2 cup water to a small saucepan. Stir in a pinch of salt.
For the microwave, combine everything in a large, microwave-safe bowl to prevent spillover.
Add flavor boosts: Mix in 1/4 to 1/2 teaspoon vanilla extract and a dash of cinnamon if using. These add warmth and depth without extra sugar.
Cook the oats: Stovetop: bring to a gentle simmer over medium heat, then lower to medium-low and cook 4–6 minutes, stirring occasionally, until creamy. Microwave: heat on high for 2–3 minutes, stir, then heat another 30–60 seconds as needed.
Prep the fruit: While the oats cook, slice 4–5 strawberries and half a banana.
Mash the remaining half banana with a fork until smooth. The mash naturally sweetens and thickens the oats.
Stir in banana and seeds: Off the heat, stir in the mashed banana and 1 teaspoon chia or ground flax (optional). Let it sit 1 minute so it thickens slightly.
Incorporate protein powder: Sprinkle in 1 scoop protein powder (about 25–30 grams). Whisk vigorously to prevent clumping, adding a splash more milk if it gets too thick.
Keep stirring until fully smooth and creamy.
Adjust sweetness and texture: Taste. Add a drizzle of honey or maple syrup if desired. Thin with extra milk for a looser texture or let it sit to thicken.
Add fresh fruit and toppings: Fold in half the sliced strawberries and banana coins.
Top the bowl with the rest. Finish with a spoonful of Greek yogurt, a small dollop of peanut or almond butter, or a sprinkle of nuts or seeds for crunch.
Serve warm: Enjoy right away for the best flavor and texture. If meal-prepping, see storage tips below.
