Shopping List

• Old-fashioned rolled oats (1/2 cup per serving)
• Milk of choice (dairy or unsweetened almond/soy/oat milk)
• Water (for extra creaminess, use half milk, half water)
• Ripe banana (half mashed into the oats, half sliced for topping)
• Peanut butter (2 tablespoons; natural, no added sugar if possible)
• Greek yogurt or vanilla/plain protein powder (optional, for an extra protein boost)
• Cinnamon and a pinch of salt
• Vanilla extract (optional)
• Honey or maple syrup (optional, to taste)
• Chia seeds or ground flaxseed (optional, for extra fiber and texture)
• Toppings: sliced banana, chopped peanuts, cacao nibs or chocolate chips, berries, a drizzle of peanut butter

Instructions

1. Heat your base: In a small saucepan, add 1/2 cup rolled oats, 1/2 cup milk, and 1/2 cup water. Stir in a pinch of salt and 1/2 teaspoon cinnamon.

   Turn heat to medium.

2. Sweeten naturally: Mash half a ripe banana and stir it into the pot. This gently sweetens the oats and makes them creamy without extra sugar.
3. Simmer and stir: Cook for 4–6 minutes, stirring often, until the oats are thick and tender. If it gets too thick, splash in more milk.
4. Add the peanut butter: Stir in 2 tablespoons peanut butter until fully melted and smooth.

   Taste, then add a few drops of vanilla if you like.

5. Boost the protein (optional): For Greek yogurt, remove the pot from heat and let it cool for 1 minute, then stir in 1/4–1/3 cup. For protein powder, whisk 1–2 tablespoons with a little milk to make a smooth slurry, then stir it into the warm oats off heat to prevent clumping.
6. Adjust sweetness: Taste and add honey or maple syrup if needed. Often the banana is enough.
7. Serve and top: Spoon into a bowl and add sliced banana, a sprinkle of chia or flax, chopped peanuts, and an extra drizzle of peanut butter.

   Add chocolate chips or cacao nibs if you want a treat.

Storage Instructions

• Make ahead: Cook a double or triple batch and store in airtight containers for up to 4 days in the fridge.
• Reheat: Add a splash of milk and warm on the stovetop over low heat or microwave in 30-second bursts, stirring until creamy again.
• Protein add-ins: If using Greek yogurt, it’s best to stir it in after reheating so the texture stays smooth.
• Freezing: Freeze portions in freezer-safe containers for up to 2 months. Thaw overnight in the fridge, then reheat with milk.

Benefits of This Recipe

• High satiety: The mix of protein, fiber, and healthy fats keeps you full and reduces mid-morning snacking.
• Balanced nutrition: Oats offer complex carbs and beta-glucan fiber; peanut butter brings healthy fats and protein; banana adds potassium and natural sweetness.
• Steady energy: No sugar spike-and-crash—just sustained fuel for work, workouts, or a busy day.
• Easy to personalize: Dairy-free, gluten-free (use certified GF oats), and customizable for different calorie and macro needs.
• Comfort factor: Warm, creamy, and nostalgic, yet grown-up enough to meet your nutrition goals.

What Not to Do

• Don’t crank the heat: High heat can scorch the oats and make them gluey. Gentle simmer is best.
• Don’t add protein powder to boiling oats: It can clump and turn grainy.

  Stir it in off heat.

• Don’t skip the salt: Just a pinch makes the flavors pop and balances the sweetness.
• Don’t over-thicken: If the oatmeal gets too stiff, add milk gradually until creamy. It should be spoonable, not paste-like.
• Don’t use green bananas: You’ll miss out on natural sweetness and creamy texture. Ripe is key.

Variations You Can Try

• PB&J Oatmeal: Swirl in a spoonful of your favorite jam and top with fresh berries.
• Chocolate Peanut Butter: Add 1 tablespoon cocoa powder and a drizzle of honey; top with cacao nibs.
• Crunch Boost: Add toasted peanuts or granola on top for texture.
• Vegan Protein: Use soy milk or pea milk for extra protein, and mix in a plant-based protein powder.
• Extra Fiber: Stir in 1 tablespoon chia seeds while cooking; add more liquid as they thicken.
• Spice It Up: Try cardamom or pumpkin pie spice instead of cinnamon for a cozy twist.
• Overnight Version: Combine oats, milk, mashed banana, cinnamon, a pinch of salt, and peanut butter in a jar.

  Chill overnight. Stir in yogurt or protein powder in the morning and add toppings.

FAQ

How much protein is in a serving?

With 1/2 cup oats, 1 cup milk, 2 tablespoons peanut butter, and 1/4 cup Greek yogurt, you’ll land around 25–30 grams of protein, depending on brands. Using protein powder can push it higher.

Can I use steel-cut or quick oats?

Yes.

Steel-cut oats need more time and liquid (about 20–25 minutes, 3:1 liquid to oats). Quick oats cook faster and turn softer; reduce cook time to 1–2 minutes.

What if I’m allergic to peanuts?

Use almond butter, cashew butter, or sunflower seed butter. All work well and still give that creamy, nutty finish.

Can I make it without banana?

Absolutely.

Skip the banana and sweeten lightly with maple syrup or honey. For creaminess, add a little extra milk or a spoon of applesauce.

Is it okay to add the Greek yogurt while cooking?

It’s better to stir it in off heat. Heating yogurt can make it curdle or turn tangy in an odd way.

How do I prevent the oatmeal from sticking?

Use a nonstick or heavy-bottomed saucepan, stir often, and keep the heat medium to low.

A quick rinse of the pot with cold water before cooking can help reduce sticking.

What’s the best way to add protein powder?

Mix the powder with a small amount of milk to form a smooth slurry, then stir it into the warm oats off heat. This prevents clumps and grit.

Can I reduce the calories?

Yes. Use powdered peanut butter, skim or almond milk, and skip sweeteners.

You’ll still get flavor and protein with fewer calories.
