Dairy Free Apple Cinnamon Baked Oatmeal with Protein Boost
There is something deeply satisfying about pulling a warm tray of baked oatmeal from the oven on a cool morning. The smell of cinnamon and soft apple filling the kitchen is honestly one of the best things about this dairy free apple cinnamon baked oatmeal. It feels indulgent. It absolutely is not. This recipe was built from the ground up to be genuinely nutritious, not just a traditional comfort dish with one small swap. Every ingredient has a purpose, and together they create something that tastes like a treat but fuels you like a proper breakfast.
What sets this version apart from the usual baked oatmeal recipes you find online is the addition of vanilla protein powder and ground flaxseed. Most baked oatmeal recipes clock in around 6 to 8 grams of protein per serving. This one delivers closer to 18 grams, which makes a real difference when you are trying to stay full and focused through the morning. The flaxseed adds omega-3 fatty acids and bumps the fibre content significantly, while the unsweetened almond milk keeps things completely dairy free without adding unnecessary calories. It is a simple idea, but the results are genuinely impressive.
The apples do a lot of heavy lifting here. Two large apples, diced and folded through the oat mixture, release natural sugars as they bake, softening into juicy pockets throughout every slice. Because the apples bring their own sweetness, you only need a small amount of pure maple syrup to round things out. No refined sugar, no hidden syrups, no artificial sweeteners. A generous amount of ground cinnamon, a little ground ginger and a pinch of nutmeg give the whole dish that warming spiced flavour that makes it feel like autumn in a bowl, no matter what time of year you make it. A flax egg binds everything together beautifully, keeping the recipe fully vegan as well as dairy free.
One of the best things about this dairy free apple cinnamon baked oatmeal is how well it lends itself to meal prep. You bake it once, slice it into six portions and you have breakfast sorted for most of the working week. Each portion reheats in the microwave in under two minutes, and it actually tastes better on day two once the spices have had time to deepen. Serve it straight from the dish with a spoonful of almond butter on top, a handful of chopped walnuts for crunch, or simply a drizzle of extra maple syrup if you want a little more sweetness. It works equally well eaten cold, almost like a slice of dense, spiced oat cake. However you enjoy it, this is the kind of breakfast that genuinely earns a regular spot in your weekly rotation.
Ingredients
- 2 cups rolled oats (use certified gluten-free oats if needed)
- 1 scoop vanilla plant-based protein powder (approximately 30g, use an unsweetened or lightly sweetened variety)
- 2 tablespoons ground flaxseed
- 1.5 teaspoons ground cinnamon
- 0.3 teaspoon ground ginger
- 0.1 teaspoon ground nutmeg
- 1 teaspoon baking powder
- 0.3 teaspoon fine sea salt
- 2 large apples (peeled and diced into 1cm cubes, Granny Smith or Honeycrisp both work well)
- 1 tablespoon ground flaxseed (for the flax egg, combined with 3 tablespoons water)
- 3 tablespoons water (to make the flax egg, mix with 1 tablespoon ground flaxseed and rest 5 minutes)
- 2 cups unsweetened almond milk (or any unsweetened dairy free milk)
- 2 tablespoons pure maple syrup (adjust to taste)
- 1 teaspoon pure vanilla extract
- 1 tablespoon coconut oil (melted, plus extra for greasing the dish)
Instructions
- 1
Preheat your oven to 180 degrees Celsius (350 degrees Fahrenheit). Lightly grease an 8x8 inch baking dish with a little coconut oil and set aside.
A glass or ceramic dish works best here as it holds heat evenly and prevents the bottom from over-browning.
- 2
Make your flax egg by combining 1 tablespoon of ground flaxseed with 3 tablespoons of water in a small bowl. Stir well and leave to sit for 5 minutes until it thickens to a gel-like consistency.
- 3
In a large mixing bowl, combine the rolled oats, protein powder, 2 tablespoons of ground flaxseed, cinnamon, ginger, nutmeg, baking powder and sea salt. Stir everything together until well mixed.
Mixing the dry ingredients thoroughly first ensures the spices and protein powder are evenly distributed through every bite.
- 4
In a separate jug or bowl, whisk together the almond milk, maple syrup, vanilla extract, melted coconut oil and the prepared flax egg.
- 5
Fold the diced apples through the dry oat mixture. Then pour the wet ingredients over the top and stir gently until everything is evenly combined. The mixture will look quite wet, which is normal.
Reserve a small handful of diced apple to scatter over the top of the dish before baking. This gives a lovely caramelised topping.
- 6
Pour the mixture into your prepared baking dish and spread it out evenly. Scatter any reserved apple pieces over the top and finish with a light extra dusting of ground cinnamon.
- 7
Bake in the preheated oven for 38 to 42 minutes, until the top is golden and the centre feels set when you press it gently. A skewer inserted into the middle should come out clean.
If the top is browning too quickly before the centre is set, loosely lay a piece of foil over the dish for the last 10 minutes.
- 8
Remove from the oven and allow to cool in the dish for at least 10 minutes before slicing. This resting time helps the oatmeal firm up into neat, sliceable portions.
It is worth waiting. Cutting too early will result in crumbly pieces that fall apart.

Pro Tips
- ✓
Use old-fashioned rolled oats rather than quick-cook oats. Quick oats absorb liquid faster and can make the texture mushy.
- ✓
Taste your apples before adding them. If they are very tart, you might want to add an extra half tablespoon of maple syrup. If they are sweet, you could reduce the syrup slightly.
- ✓
Do not skip the flax egg. It is what binds the baked oatmeal together and gives each slice structure.
- ✓
The baked oatmeal will firm up considerably as it cools. If it looks a little wobbly when you first take it out of the oven, give it the full 10-minute resting time before worrying.
- ✓
For extra warmth and depth of flavour, add a quarter teaspoon of ground cardamom to the spice blend.
Frequently Asked Questions
Variations
- •
Pear and Cardamom
Swap the apples for two ripe but firm pears and replace the ginger with half a teaspoon of ground cardamom. The result is a more floral, elegant flavour that pairs beautifully with a drizzle of almond butter.
- •
Apple Raisin Walnut
Fold 3 tablespoons of raisins and 3 tablespoons of roughly chopped walnuts into the oat mixture along with the apples. This adds natural sweetness, healthy fats and extra crunch.
- •
Chocolate Chip Apple
Stir 2 tablespoons of dairy free dark chocolate chips into the mixture just before pouring it into the baking dish. The chocolate melts into pockets throughout the oatmeal for a slightly indulgent twist that still keeps the overall sugar reasonable.
Substitutions
- •Almond milk → Oat milk, coconut milk (carton) or soy milk (Use unsweetened varieties to control the overall sugar content of the dish.)
- •Maple syrup → Agave nectar or raw honey (Note that honey makes the recipe no longer vegan. Use the same quantity as maple syrup.)
- •Coconut oil → Light olive oil or avocado oil (Both work well and have a neutral enough flavour to complement the spices.)
- •Flax egg → 1 medium egg (if not vegan) (Using a regular egg gives a slightly firmer, more cake-like texture and increases the protein content further.)
- •Vanilla plant-based protein powder → 2 tablespoons of extra rolled oats or ground almonds (The protein per serving will decrease but the texture remains excellent.)
🧊 Storage
Allow the baked oatmeal to cool completely before covering the dish tightly with a lid or cling film. Store in the refrigerator for up to 5 days. To reheat, microwave individual portions for 60 to 90 seconds, adding a small splash of almond milk to loosen if desired. You can also reheat slices in a low oven at 160 degrees Celsius for about 10 minutes.
📅 Make Ahead
Assemble the full recipe the evening before, cover the unbaked dish and refrigerate overnight. Bake fresh the following morning, allowing an extra 5 minutes of cooking time. Alternatively, bake a full batch on Sunday and refrigerate the sliced portions to enjoy throughout the week.
