Cooking Time

• Preparation Time: 10 minutes

• Resting Time: 5 minutes (for oats to absorb moisture)

• Baking Time: 50 minutes

• Total Time: Approximately 1 hour and 5 minutes

Ingredients

• 130 g rolled oats

• 100 g plain yogurt

• ½ tsp baking powder

• 240 ml warm water

• 50 ml avocado oil (or any neutral oil)

• 2 tbsp stevia (or preferred granulated sweetener)

• 2 egg whites

• 1 tsp vanilla extract

• 30 g almond flakes

• 200 g blueberries (fresh or frozen)

Step-by-Step Cooking Directions

Step 1: Prepare the Oats
In a large mixing bowl, combine the oats, yogurt, baking powder, and warm water. Stir well and let the mixture rest for 5 minutes. This softens the oats and gives the baking powder time to activate, ensuring a fluffier texture.

Step 2: Add the Wet Ingredients
After the oats have absorbed the liquid, whisk in avocado oil, stevia, egg whites, and vanilla extract. Stir until the mixture is well combined and smooth.

Step 3: Add Blueberries and Almonds
Gently fold in the blueberries (especially if using fresh ones to avoid breaking them) and most of the almond flakes. Reserve a few flakes to sprinkle over the top of the cake before baking.

Step 4: Bake the Cake
Preheat your oven to 180°C (360°F). Grease or line a baking dish or loaf tin with parchment paper. Pour in the batter and smooth the surface. Top with the remaining almond flakes.
Bake for 50 minutes, or until the top is golden and a toothpick inserted into the center comes out clean or with just a few moist crumbs.

Step 5: Cool and Serve
Let the cake cool in the pan for 10 minutes before slicing. Serve warm or at room temperature, and enjoy!

Altogether, it’s a nourishing option that supports digestive health, energy levels, and overall well-being.

Serving Suggestions

• Pair with coffee or a matcha latte for a cozy breakfast

• Add a sprinkle of cinnamon or nutmeg on top for warmth

• Enjoy chilled with a side of cottage cheese or kefir

• Turn it into dessert with a spoonful of whipped coconut cream

Common Mistakes to Avoid

• Not letting the oats soak: This step ensures the right texture and fluffiness.

• Using cold water: Warm water helps break down the oats faster and activates the baking powder.

• Overmixing: Once the blueberries are added, stir gently to prevent batter breakdown.

• Not preheating the oven: For even baking, the oven should be fully preheated.

• Overbaking: Check the cake at the 45-minute mark to prevent it from drying out.

• Using too much sweetener: Stevia is potent; adding too much can create a bitter aftertaste.

Pairing Recommendations

• Drinks: Pair with black coffee, herbal teas like chamomile or peppermint, or a smoothie.

• Savory side: Enjoy with a hard-boiled egg or a slice of cheese for protein balance.

• Fruit: Add a side of sliced strawberries or a banana.

• Dairy: Serve with plain kefir, skyr, or cottage cheese for added creaminess.

Cooking Tips

• Use quick-cooking oats for a softer texture or rolled oats for more bite.

• Substitute stevia with honey or maple syrup for a more traditional sweetness (adjust quantity).

• For richer flavor, replace some water with almond or oat milk.

• Add chia seeds or flaxseed meal for extra fiber and nutrition.

• Don’t skip the almond flakes—they add a toasted crunch that elevates the dish.

Ingredient Spotlight: Blueberries

Blueberries are one of the most antioxidant-rich fruits available. They are low in calories, high in fiber, and packed with vitamin C, vitamin K, and manganese. Their deep blue color comes from anthocyanins, compounds that support brain health, reduce inflammation, and promote heart health. In baking, they add bursts of sweetness and moisture, balancing hearty textures like oats perfectly.

10 Comprehensive Frequently Asked Questions

1. Can I use steel-cut oats instead of rolled oats?
Not in this recipe. Steel-cut oats won’t absorb moisture quickly enough and will stay too hard.

2. Is this cake gluten-free?
Yes, as long as your oats are certified gluten-free.

3. Can I use whole eggs instead of just egg whites?
Yes, two egg whites equal one whole egg. You can use one whole egg if preferred, though it will slightly increase the fat content.

4. What’s a good stevia substitute?
You can use 2 tbsp of honey, maple syrup, or coconut sugar. Adjust the wet ingredients slightly if needed.

5. Can I use frozen blueberries?
Yes, no need to thaw. Just fold them in gently to avoid bleeding into the batter.

6. Can I make this in a muffin tin?
Absolutely! It makes about 8–10 muffins. Reduce baking time to 25–30 minutes and check doneness with a toothpick.

7. How do I store leftovers?
Store in an airtight container at room temperature for 2 days, or refrigerate for up to 5 days.

8. Can I freeze this cake?
Yes, slice and freeze in portions. Reheat in a microwave or toaster oven.

9. Why didn’t my cake rise much?
Ensure your baking powder is fresh and that the oats had time to soak. Also, don’t overmix the batter after adding baking powder.

10. Can I double the recipe for a larger batch?
Yes, simply double all ingredients and use a larger pan. Add 5–10 minutes to baking time, and check with a toothpick.
