Ingredients

• Rolled Oats (120 g) — Provides heart-healthy soluble beta-glucan fiber for lasting satiety and smooth digestive health.
• Unsweetened Almond Milk (240 ml) — Blends the oat batter into a silky consistency while keeping the recipe light and dairy-free.
• Ripe Banana (100 g) — Adds natural sweetness, potassium, and moisture without the need for refined sugars.
• Vanilla Protein Powder (30 g) — Elevates the protein content to support lean muscle repair and keep hunger signals quiet.
• Pure Maple Syrup (15 ml) — Offers a touch of unrefined, mineral-rich sweetness that perfectly balances the citrus notes.
• Fresh Lemon Zest and Juice (1 lemon / ~5 g zest, 15 ml juice) — Delivers a bright, zestful citrus punch that cuts through the richness of the oats.
• Baking Powder (5 g) — Gives the batter a light, airy rise and an authentic baked-cake texture.
• Fine Sea Salt (1 g) — Enhances all the natural sweet and citrus flavors for a rounded taste profile.
• Fresh Blueberries (100 g) — Creates juicy, antioxidant-packed pockets of flavor throughout every slice.

Step-by-Step Instructions

1. Preheat your oven to 180°C (350°F) and lightly coat a medium baking dish or two individual ramekins with coconut oil spray.
2. Blend the rolled oats, almond milk, ripe banana, vanilla protein powder, maple syrup, lemon zest, lemon juice, baking powder, and sea salt in a high-speed blender for 30 seconds until completely smooth.
3. Fold 80 g of the fresh blueberries gently into the blended batter using a flexible spatula to keep the berries intact.
4. Pour the batter evenly into your prepared baking dish and scatter the remaining 20 g of blueberries over the top.
5. Bake for 22 to 25 minutes, until the top is set, golden around the edges, and a toothpick inserted into the center comes out clean.
6. Cool for 5 minutes before serving warm, optionally topped with a splash of milk or a dollop of Greek yogurt.

Tips for the Best Lemon Blueberry Baked Oats

• Don't skip the fresh zest: Bottled lemon juice lacks the essential aromatic oils found in fresh skin; always use a fine microplane for real citrus depth.
• Careful with frozen berries: If using frozen blueberries, fold them in straight from the freezer without thawing so they don't streak the batter purple.
• Watch the bake time: Avoid over-baking, as protein powder can dry out if left in the oven too long. The center should feel firm yet springy.

Storage and Freezing Instructions

• Refrigeration: Allow leftovers to cool completely, cover tightly, and store in the fridge for up to 4 days. Reheat in the microwave for 45–60 seconds.
• Freezing: Slice into individual portions, wrap tightly in parchment paper and foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before warming up.

Lemon Blueberry Baked Oats Your Way

• Banana-Free: Replace the mashed banana with 100 g of plain Greek yogurt or unsweetened unsweetened applesauce.
• Nut-Free: Swap almond milk for oat milk or unsweetened soy milk.
• Gluten-Free: Ensure your rolled oats are certified gluten-free to avoid cross-contamination.
• Extra Crunchy: Sprinkle 15 g of sliced almonds or chia seeds on top before baking for added texture and healthy fats.

Make Ahead

You can easily prepare the batter the night before! Blend all liquid and dry base ingredients together, store in an airtight container in the fridge overnight, and fold in the blueberries right before pouring into your dish and baking the next morning.

Frequently Asked Questions

Can I use quick oats instead of rolled oats?
Yes! Since the ingredients are processed in a blender, quick oats will yield the exact same creamy oat flour texture.

Can I make this in an air fryer?
Absolutely! Place your air-fryer safe dish into the basket and bake at 160°C (320°F) for 15 to 18 minutes until set.

Why did my baked oats turn out dry?
Dry baked oats are usually caused by over-baking or using an overly absorbent whey protein powder. Try reducing the bake time by 2–3 minutes or swapping to a plant-based protein powder blend.
