Healthy Homemade Granola: Crunchy Cinnamon & Vanilla Toasted Oats

A delicious, lower-sugar alternative to store-bought granola that's easy to make at home.

Love the sweet crunch of granola on your morning yoghurt, but wish you could enjoy it with a little less added sugar and oil?

This homemade cinnamon and vanilla toasted oats recipe might be just what you're looking for! Golden, crunchy and lightly sweetened, these toasted oats give you that satisfying granola-like texture using just a handful of everyday ingredients.

And the best part? You can adjust the sweetness to suit your taste.

Is store-bought granola actually healthy?

Granola often has a healthy reputation, and for good reason. Many varieties contain nutritious ingredients such as wholegrain oats, nuts and seeds.

However, depending on the brand, granola can also contain substantial amounts of added sugar and oil.

Ingredients such as honey, maple syrup, coconut oil and dried fruit can make granola quite energy-dense. These aren't necessarily unhealthy ingredients, but the amounts used can make a difference, particularly if you're looking for a lighter breakfast topping.

The solution isn't to avoid granola. It's to find a version that works for you.

Making your own means you can control how much sugar and oil you add while still enjoying the crunch and sweetness.

Why I love these homemade cinnamon toasted oats

As a dietitian, I'm always looking for practical ways to make everyday meals both nutritious and enjoyable.

I particularly love having something crunchy to sprinkle over Greek yoghurt or fruit. It adds texture and flavour without needing a large portion.

This recipe uses traditional rolled oats, cinnamon, vanilla, a little brown sugar and a light spray of vegetable oil.

Unlike traditional granola, which often contains larger quantities of nuts, seeds, oil and sweeteners, this version keeps things simple.

5 nutritional benefits of homemade toasted oats

1. A source of wholegrains

Rolled oats are a wholegrain, providing carbohydrates, fibre and nutrients including magnesium, phosphorus and B vitamins.

Wholegrain foods are an important part of a balanced eating pattern and are associated with better long-term cardiovascular health.

2. Contains beta-glucan fibre for heart health

Oats contain beta-glucan, a type of soluble fibre that can help lower LDL cholesterol when consumed regularly in sufficient amounts.

A small sprinkle of these toasted oats contributes some beta-glucan, although you'll need larger portions of oats and other fibre-rich foods throughout the day to achieve cholesterol-lowering intakes.

3. Supports digestive health

Oats provide dietary fibre, which contributes to healthy bowel function. Including a variety of fibre-rich foods throughout the day also helps support digestive health.

4. Less added sugar

This recipe uses just 15 g of brown sugar across the entire batch, approximately 1.5 g per serving.

You can reduce this further by using a sugar substitute or combining a small amount of brown sugar with an alternative sweetener.

5. A lighter breakfast topping

By using a light spray of oil rather than several tablespoons, this recipe keeps the added fat and energy relatively low.

Each serving provides approximately 65 calories, making it a useful option when you want some crunch without a large portion of granola.

Remember, lower calorie doesn't automatically mean healthier. Nuts and seeds found in many traditional granolas also provide beneficial fats, protein and nutrients.

Recipe: Crunchy Cinnamon & Vanilla Toasted Oats

Preparation: 5 minutes Cooking: 15–20 minutes Makes: Approximately 10 servings

Serving size: Approximately 15–17 g (around ¼ cup, depending on texture)

Ingredients

• 150 g traditional rolled oats (approximately 1⅔ cups)

• 15 g brown sugar (approximately 1 tablespoon, packed)

• 4 g ground cinnamon (approximately 1½ teaspoons)

• 5 mL vanilla extract (1 teaspoon)

• 40 mL water (2 Australian tablespoons)

• Approximately 2 g canola oil or light olive oil, applied using a refillable oil spray bottle (around 8–10 sprays, depending on the bottle)

• Pinch of salt

Australian metric measures: 1 cup = 250 mL, 1 tablespoon = 20 mL and 1 teaspoon = 5 mL. Cup-to-gram conversions are approximate.

Method

1. Preheat your oven to 160°C fan-forced and line a baking tray with baking paper.

2. Combine rolled oats, brown sugar, cinnamon and salt in a mixing bowl.

3. Mix vanilla extract with water and drizzle over the oats. Stir until evenly coated.

4. Spread the oats in a thin, even layer over the baking tray.

5. Using a refillable oil spray bottle filled with canola oil or light olive oil, lightly mist the oats to distribute approximately 2 g of oil across the mixture.

6. Bake for 15–20 minutes, stirring halfway, until lightly golden and fragrant.

   
   

Allow to cool completely on the tray. The oats will become crunchier as they cool.

Transfer to an airtight container once completely cooled.

Dietitian's tip: A refillable oil spray bottle is a handy kitchen tool for controlling the amount of oil used in cooking. A neutral-tasting vegetable oil such as canola oil works beautifully, while a light olive oil is another good option. Both help distribute a small amount of oil evenly across the oats, encouraging golden, crunchy results without needing to pour oil over the mixture.

For the best crunch, spread the oats thinly and allow them to cool completely before storing.

Want to reduce the sugar even further?

This recipe is easy to adapt.

Version	Sweetener alternative
Original	15 g brown sugar
Reduced sugar	5 g brown sugar + 10 g erythritol-based sweetener
No added sugar	Brown sugar-style erythritol sweetener, adjusted to taste
Stevia	A few drops of liquid stevia, adjusted to taste
Allulose	15–20 g allulose, where available

Brown sugar helps create a slightly caramelised flavour, while sugar substitutes provide sweetness without necessarily providing the same browning properties. Check the manufacturer's sweetness conversion when using alternatives.

How to enjoy your homemade granola alternative

These cinnamon toasted oats are delicious sprinkled over:

• High-protein Greek yoghurt with fresh berries

• Overnight oats or chia pudding

• Stewed apples or pears

• Smoothie bowls

• Cottage cheese with fruit

• Plain yoghurt with banana and cinnamon

My favourite combination is Greek yoghurt, berries and a sprinkle of cinnamon toasted oats.

You get a lovely combination of creamy, sweet and crunchy textures, with protein from the yoghurt, fibre from the oats and fruit, and plenty of flavour.

A dietitian's final thoughts

Healthy eating doesn't have to mean giving up foods you enjoy.

Sometimes a small adjustment to an everyday favourite can help you find a balance between flavour, nutrition and your individual health goals.

This homemade granola alternative is a great example. It's simple, inexpensive, easy to prepare and adaptable to your taste.

And if you prefer your favourite store-bought granola? That's absolutely fine too.

The aim isn't perfection. It's having options that make eating well easier and more enjoyable.

1. FAQ

2. Is homemade granola healthier than store-bought granola?

   It depends on the ingredients and portion size. Homemade granola allows you to control the added sugar and oil, while some commercial granolas provide valuable fibre, nuts and seeds.

3. Can I make granola without oil?

   Yes. Oats can be toasted without oil, although a small amount can improve browning and texture.

4. Are toasted oats good for cholesterol?

   Oats contain beta-glucan, a soluble fibre that can help reduce LDL cholesterol when consumed in sufficient quantities as part of a healthy diet. A small granola topping contributes only part of that intake.

5. How do I keep homemade granola crunchy?

   Spread the oats thinly while baking, allow them to cool completely, and store them in an airtight container away from moisture.
