What You’ll Need
- Old-fashioned rolled oats: The best texture for this recipe.
Avoid instant unless you reduce cooking time.
- Water + unsweetened almond milk (or skim milk): A mix keeps it creamy while staying light.
- Raisins: Classic and naturally sweet. Golden or regular both work.
- Ground cinnamon: The star flavor. Use a generous pinch.
- Pinch of salt: Makes the flavors pop.
- Vanilla extract: Adds warmth and a bakery-like aroma.
- Sweetener of choice (optional): Stevia, monk fruit, maple syrup, or honey—go light to keep it calorie-friendly.
- Optional protein boost: Unflavored or vanilla protein powder, or plain Greek yogurt for serving.
- Optional topping ideas: A few chopped walnuts or almonds, extra cinnamon, sliced banana, or a teaspoon of flaxseed or chia.
How to Make It

- Combine the base: In a small saucepan, add 1/2 cup rolled oats, 1/2 cup water, and 1/2 cup unsweetened almond milk (or skim milk).
Stir in a pinch of salt.
- Add flavor early: Sprinkle in 1/2 to 1 teaspoon ground cinnamon and 2 tablespoons raisins. Cooking the raisins with the oats plumps them up and sweetens the bowl naturally.
- Simmer gently: Bring to a gentle simmer over medium heat, then reduce to medium-low. Cook, stirring occasionally, for 5–7 minutes until creamy and the oats are tender.
- Finish with vanilla: Remove from heat and stir in 1/2 teaspoon vanilla extract.
Taste and add a touch of sweetener if you like.
- Optional protein step: If using protein powder, whisk 1–2 tablespoons with a splash of milk in a separate cup to make a smooth slurry, then stir into the warm oats off heat. If using Greek yogurt, swirl it in right before serving.
- Serve and top: Spoon into a bowl. Add a dusting of cinnamon, a few chopped nuts, or sliced banana if you want more heft without many extra calories.
Microwave method: Combine everything except vanilla in a large microwave-safe bowl (oats expand).
Cook on High for 2–3 minutes, stir, then another 30–60 seconds as needed. Stir in vanilla at the end.
How to Store
- Refrigerate: Store cooked oatmeal in an airtight container for up to 4 days.
- Reheat: Splash in 2–4 tablespoons milk or water and warm on the stove or in the microwave, stirring halfway. Add a little extra cinnamon to refresh flavor.
- Meal prep tip: Portion into single-serve containers so mornings are grab-and-go.
Add fresh toppings after reheating.
- Freezing: Possible, but texture softens. Freeze in portions up to 1 month; thaw overnight and reheat with extra liquid.

Health Benefits
- High in fiber: Rolled oats provide beta-glucan, a soluble fiber that supports heart health and steady energy.
- Steady blood sugar: The fiber and slow-digesting carbs help prevent spikes, especially when paired with protein.
- Naturally sweetened: Raisins add sweetness, iron, and potassium without relying on heavy sugar.
- Lower calorie base: Using water and unsweetened almond milk keeps the bowl creamy with fewer calories.
- Protein boost options: Add protein powder or Greek yogurt for a more balanced, post-workout bowl.
What Not to Do
- Don’t skip the salt: A tiny pinch makes the cinnamon and vanilla shine. Without it, the bowl can taste flat.
- Don’t add protein powder directly to hot oats: It can clump.
Mix with a splash of milk first, then stir in off heat.
- Don’t drown it in sweetener: Start small. Raisins and cinnamon already bring sweetness.
- Don’t overcook: Too much heat dries it out. Aim for creamy with some texture.
- Don’t use a small microwave bowl: Oats bubble up.
Use a large bowl to avoid a mess.
Recipe Variations
- Apple Cinnamon Raisin: Grate half an apple into the pot while cooking for extra volume and natural sweetness.
- High-Protein: Stir in 1/2 scoop vanilla protein powder (pre-slurried) or top with 1/4 cup plain Greek yogurt.
- Nutty Crunch: Add 1 tablespoon chopped walnuts or almonds for texture and healthy fats.
- Gluten-Free: Use certified gluten-free oats and the same method.
- Spice Lover’s: Add a pinch of nutmeg or cardamom with the cinnamon for a bakery-style aroma.
- Maple Morning: Skip other sweeteners and finish with 1–2 teaspoons pure maple syrup and extra cinnamon.
- Overnight Oats Style: Combine 1/2 cup oats, 1/2 cup almond milk, 1/4 cup water, cinnamon, raisins, vanilla, and a pinch of salt. Chill overnight and enjoy cold or warmed with a splash more milk.
- Banana Bread Bowl: Mash 1/3 ripe banana into the pot at the end for natural sweetness and creaminess.
FAQ
Can I use steel-cut oats instead of rolled oats?
Steel-cut oats need more liquid and time. Use about 3 cups liquid per 1 cup oats and simmer 20–30 minutes.
Add raisins halfway through so they plump without breaking down.
Are instant oats okay?
Yes, but reduce the liquid slightly and cut the cook time. The texture will be softer and less chewy than rolled oats.
What’s the best way to add protein without changing flavor?
Use unflavored or vanilla whey or a light plant protein. Make a slurry with a splash of milk, then stir it into warm (not boiling) oats.
Greek yogurt is another neutral option.
How can I keep calories low but still feel full?
Use half water and half unsweetened almond milk, go easy on sweeteners, and add volume with grated apple or extra cinnamon. A small scoop of protein powder or a spoon of Greek yogurt boosts satiety.
Do I need to soak the raisins?
Not necessary. Cooking them with the oats plumps them.
If you like extra-juicy raisins, soak in warm water for 5 minutes and drain before adding.
Can I make this dairy-free?
Absolutely. Use almond, oat, or soy milk, and skip dairy toppings. Check your protein powder if using to ensure it’s dairy-free.
Why did my oatmeal turn gummy?
Overcooking or too much stirring can make oats pasty.
Keep the heat moderate, stir occasionally, and add a splash more liquid near the end if it thickens too much.
