🥣 Ingredients

For one 6-inch (15 cm) round cake — approximately 6 servings:

• 1 cup rolled oats (90 g)
• 1 large ripe banana
• 2 large eggs
• ½ cup plain Greek yogurt (120 g)
• 1 tablespoon honey (optional)
• 1 teaspoon baking powder
• ½ teaspoon vanilla extract (optional)
• ¼ teaspoon ground cinnamon (optional)
• A small pinch of salt

Fresh fruit filling:

• ¼ cup fresh pineapple, finely diced (40 g)
• ¼ cup ripe mango, finely diced (40 g)
• ¼ cup fresh strawberries, chopped (40 g)

Optional toppings:

• Fresh strawberry slices
• A spoonful of Greek yogurt
• A light drizzle of honey
• Chopped nuts

👩‍🍳 Step-by-Step Instructions

Step 1: Make Homemade Oat Flour

Add 1 cup of rolled oats to a high-speed blender.

Blend for approximately 20–30 seconds until the oats turn into a fine, flour-like powder.

This homemade oat flour gives the cake a tender texture without using regular wheat flour.

Tip: Blend the oats as finely as possible for a softer cake.

Step 2: Add the Wet Ingredients

To the blender containing the oat flour, add:

• 1 ripe banana, peeled and broken into chunks
• 2 large eggs
• ½ cup Greek yogurt
• 1 tablespoon honey, if desired
• ½ teaspoon vanilla extract

Blend until the ingredients become smooth and creamy.

The banana provides natural sweetness, while the yogurt helps keep the cake moist.

Step 3: Add the Baking Powder

Add 1 teaspoon of baking powder, a pinch of salt, and optional cinnamon.

Pulse briefly until combined.

The batter should be thick, creamy, and pourable.

If the batter is too thick, add 1–2 tablespoons of milk. Avoid adding too much liquid.

Step 4: Fold in the Fresh Fruit

Pour the blended batter into a mixing bowl.

Add the diced pineapple, mango, and strawberries.

Using a silicone spatula, gently fold the fruit into the batter.

Important: Do not blend the fruit. Keeping the pieces intact creates delicious, juicy fruit pockets throughout the cake.

Pat very juicy fruit pieces dry with a paper towel before adding them to prevent excess moisture.

Step 5: Prepare the Baking Pan

Preheat your oven to 350°F (175°C).

Line a 6-inch round cake pan with parchment paper.

Lightly grease the sides if necessary.

Pour the fruit-filled batter into the prepared pan.

Spread the surface evenly using a spatula.

You can arrange a few extra strawberry or mango pieces on top for decoration.

Step 6: Bake Until Golden and Fluffy

Place the cake in the preheated oven.

Bake for approximately 25–35 minutes, depending on your oven and the moisture content of the fruit.

The cake is ready when:

• The surface looks lightly golden.
• The center feels set and springs back gently.
• A toothpick inserted into a cake-only section comes out clean or with a few moist crumbs.

If the top browns too quickly, cover it loosely with aluminum foil during the final minutes.

Do not overbake! This cake tastes best when the inside remains soft and moist.

Step 7: Cool, Slice, and Enjoy

Remove the cake from the oven and allow it to cool in the pan for about 10–15 minutes.

Carefully transfer it to a cooling rack.

Once it has cooled enough to hold its shape, cut a generous triangular slice.

Look at that beautiful interior! 😍

You’ll see a tender oatmeal crumb filled with colorful pieces of pineapple, mango, and strawberries.

Serve it slightly warm or at room temperature.

For an extra-special treat, add a spoonful of Greek yogurt and a few fresh berries.

💡 7 Tips for the Perfect Oatmeal Fruit Cake

1. Use a very ripe banana. A banana with brown spots is naturally sweeter and helps create a softer cake.

2. Choose thick Greek yogurt. It adds moisture without making the batter overly watery.

3. Cut the fruit into small pieces. Large chunks can sink to the bottom or create overly wet pockets.

4. Drain juicy fruit. Fresh pineapple and strawberries can release extra liquid during baking.

5. Don’t overblend after adding baking powder. A brief pulse is enough.

6. Check the center before removing the cake. Fruit-heavy cakes sometimes need a few extra minutes to bake fully.

7. Allow the cake to cool before slicing. This helps the crumb set and prevents the cake from falling apart.

🍯 Is This Cake Really Sugar-Free?

This cake contains no refined sugar when prepared without added table sugar.

However, bananas, mangoes, pineapple, and strawberries naturally contain sugar. Honey also contains sugar.

If you prefer a recipe with no added sugar, simply leave out the honey and rely on the sweetness of the ripe banana and fruit.

The cake will still have a pleasant, naturally fruity flavor.

🧊 How to Store Your Oatmeal Fruit Cake

Refrigerator: Store the cooled cake in an airtight container for up to 3–4 days.

Freezer: Wrap individual slices tightly and freeze for up to 2 months for best quality.

To reheat: Warm a slice briefly in the microwave or oven until heated through.

Because this cake contains fresh fruit and yogurt, avoid leaving it at room temperature for extended periods.

❓ Frequently Asked Questions

Can I make this cake without honey?

Absolutely! Use a very ripe banana and sweet fruit. The cake will still taste delicious without added honey.

Can I use regular yogurt instead of Greek yogurt?

Yes, but choose a thick yogurt if possible. Thin yogurt may make the batter too wet.

Can I use frozen fruit?

Yes! Use small frozen fruit pieces and avoid adding excess ice or liquid. The baking time may increase slightly.

Can I make this recipe gluten-free?

Yes, use certified gluten-free rolled oats and ensure all other ingredients are gluten-free.

Why is my oatmeal cake too dense?

Possible reasons include too much fruit, excessive liquid, insufficient baking time, or baking powder that is no longer active.

For the best texture, measure your ingredients carefully and avoid overloading the batter with fruit.
