Healthy Oatmeal Banana Apple Cake Recipe
Ingredients
- Oatmeal (Rolled or Quick Oats): 1 cup (90-100 g)
- Milk (Any kind): 150 ml ($approx 2/3$ cup)
- Bananas: 2 large
- Eggs: 2 large
- Vanilla Sugar: 1 tablespoon (15 g) – Optional: Substitute with 1 tsp vanilla extract + 1 tbsp erythritol or stevia for true sugar-free.
- Baking Powder: 1 tablespoon (15 g)
- Raisins: 4 tablespoons ($approx 60$ g)
- Apple: 1 medium
Step-by-Step Instructions
Follow these simple steps to create your easy diet cake.
Step 1: Prep the Wet Ingredients & Oats
- Preheat your oven to 180°C (360°F) and lightly grease or line a small loaf pan or a 6-inch (15 cm) round baking dish.
- In a large bowl, mash the 2 bananas thoroughly until they form a smooth paste.
- Whisk in the 2 eggs and 150 ml of milk until well combined.
- Stir in the 1 cup of oatmeal and let the mixture sit for about 5 minutes. This allows the oats to absorb some of the moisture, resulting in a softer final texture.
Step 2: Combine Dry Ingredients
- Add the 1 tablespoon of baking powder and 1 tablespoon of vanilla sugar (or your sugar substitute) to the banana-oat mixture. Mix well.
- Fold in the 4 tablespoons of raisins.
Step 3: Add the Apple
- Peel and finely grate or chop the 1 apple. Grating makes the apple pieces almost disappear into the batter, adding pure moisture and flavor.
- Gently fold the grated or chopped apple into the cake batter until evenly distributed. Be careful not to overmix.
Step 4: Bake Your Healthy Cake
- Pour the cake batter into your prepared pan.
- Bake in the preheated oven for approximately 40 minutes.
- The cake is done when a toothpick inserted into the center comes out clean.
- Remove from the oven, allow to cool in the pan for 10 minutes, and then transfer to a cooling rack.

Why This Oatmeal Cake is a Healthy Choice
This healthy cake recipe is a powerhouse of nutrition, making it a great addition to a balanced diet:
- High in Fiber: The base of oatmeal and the addition of apple and raisins provide a significant amount of dietary fiber, which aids digestion and promotes satiety, helping you feel fuller for longer.
- Natural Sweeteners: By relying heavily on the sweetness of bananas and apples, this recipe drastically cuts down on refined sugars compared to traditional cakes.
- Sustained Energy: Oats are a complex carbohydrate, meaning they release energy slowly. This helps stabilize blood sugar levels, preventing the energy crash often associated with sugary snacks, making it an ideal breakfast cake.
