Cooking Time

Preparation: 15 minutes
Soaking & Resting: 5 minutes
Baking: 40 minutes
Cooling: 20 minutes
Total Time: approx. 1 hour 20 minutes

Ingredients

1 cup (100 g) rolled oats
200 ml (¾ cup) milk (any variety)
2 large eggs
A pinch of fine salt
½ tsp pure vanilla extract
2 very ripe bananas, mashed (about 200 g)
1 medium apple, peeled and chopped (about 150 g)
½ cup (60 g) cranberries (fresh or rehydrated if dried)
½ cup (60 g) walnuts, chopped
Nonstick spray or butter, for greasing

Step-by-Step Cooking Directions

Preheat & Prep Oats
Preheat your oven to 180 °C (360 °F). In a medium bowl, whisk together the milk, eggs, salt, and vanilla extract. Stir in the mashed bananas until the mixture is smooth and uniform. Add the rolled oats, stirring to coat, then let the oats soak for 5 minutes. This brief rest softens the oats and ensures a tender cake texture.
Fold in Fruit & Nuts
While the oats soak, peel and chop the apple into roughly 1 cm cubes. Gently fold the apple pieces into the oat mixture, followed by the cranberries and chopped walnuts. Mix just until combined—overmixing can make the cake dense.
Prepare the Pan
Line a 7-inch (18 cm) round or square baking pan with parchment paper, or grease generously with butter or nonstick spray. Wetting the parchment lightly helps it conform to the pan shape.
Transfer & Bake
Pour the batter into the prepared pan, spreading it evenly with a spatula. Bake on the center rack for 40 minutes, or until the top is golden and a toothpick inserted into the center comes out with just a few moist crumbs.
Cool & Slice
Remove the cake from the oven and let it cool in the pan for 20 minutes. This allows the structure to set and makes slicing easier. Lift the cake out by the parchment edges and transfer to a wire rack to cool fully. Slice into 8–10 squares or wedges.

The Origins and Popularity of the Recipe

Oat-based bakes trace their roots to early Scandinavian porridges and British flapjacks—simple, hearty preparations designed to fuel laborers with whole-grain energy. The practice of combining oats with eggs and milk to create a cake-like texture emerged as home bakers sought healthier, flour-free desserts. Bananas, introduced to European and North American tables in the 19th century, became popular as a natural sweetener in quick breads. Adding apples and nuts draws on autumnal traditions of fruit-and-nut cakes. Today, this type of cake has soared in health-food circles and on social media as a gluten-free, whole-grain alternative to conventional baked goods, beloved for its simplicity and adaptability.

Reasons Why You’ll Love the Recipe

Minimal Ingredients: Uses pantry staples and seasonal fruit.
One-Bowl Ease: No need for separate dry and wet mixing bowls—cleanup is a breeze.
Naturally Sweetened: Bananas and apples provide sweetness, reducing added sugar.
Texture Contrast: Chewy oats, tender fruit pockets, and crunchy walnuts.
Versatile: Enjoy warm for breakfast or chilled as a snack all week.

Health Benefits

Oats: Rich in beta-glucan fiber, which supports heart health and satiety.
Bananas: Provide potassium and natural sugars for gentle energy.
Apples: Contribute vitamin C, pectin fiber, and moisture.
Walnuts: Deliver omega-3 fatty acids and plant-based protein.
Cranberries: Offer antioxidants and tart flavor with low glycemic impact.

Serving Suggestions

Breakfast Bowl: Top slices with Greek yogurt, a drizzle of honey, and fresh berries.
Afternoon Snack: Serve with a warm cup of chai tea or black coffee.
Kids’ Lunchbox: Pack a slice alongside apple slices and carrot sticks.
Light Dessert: Pair with a scoop of vanilla ice cream and sliced bananas for a special treat.

Common Mistakes to Avoid

Over-Soaking Oats: Soaking more than 10 minutes can yield a gummy texture. Follow the 5-minute rest.
Underripe Bananas: Lack of sweetness and binding power; always use very ripe (spotted) bananas.
Overmixing Batter: Mix only until ingredients are just combined—overmixing activates oat starches, making the cake dense.
Too Shallow Pan: Using a pan that’s too wide results in a dry, thin cake. Stick to an 18 cm pan for proper thickness.

Pairing Recommendations

Spreads: Almond butter or ricotta cheese with a sprinkle of cinnamon.
Drinks: A fresh fruit smoothie or sparkling water with lemon.
Yogurt: Plain or vanilla-flavored Greek yogurt adds creaminess and tang.

Cooking Tips

Uniform Fruit Size: Chop the apple into evenly sized pieces so each bite has consistent flavor.
Room-Temperature Eggs and Milk: Helps the batter come together smoothly without clumps.
Check for Doneness Early: Ovens vary—begin testing at 35 minutes to avoid overbaking.
Let Rest Before Slicing: A 20-minute rest in the pan ensures clean edges when cutting.

Add a tablespoon of pure maple syrup or increase banana quantity if they’re extra ripe.
Can I add spices to the batter?
