Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

2 large ripe bananas (about 1 cup mashed), mashed until completely smooth
1 cup fresh strawberries, blended until smooth
1 cup all-purpose flour, sifted
1 to 2 tablespoons honey or maple syrup (optional, for drizzling after baking)

Directions

1. Preheat your oven to 350°F (175°C). Line an 8-inch round or square cake pan with parchment paper to prevent sticking.
2. In a large mixing bowl, mash the ripe bananas thoroughly until smooth and lump-free. The texture should resemble a thick puree.
3. Add the blended strawberries to the mashed bananas. Stir until fully combined. The mixture will turn a vibrant pink and have a naturally sweet, fruity aroma.
4. Gradually fold in the sifted all-purpose flour. Mix gently until just combined. Avoid overmixing, as this can make the cake dense. The batter should be thick yet pourable.
5. Pour the batter into the prepared pan and smooth the top evenly with a spatula.
6. Bake for 30 to 35 minutes, or until the edges are lightly golden and the center is set. A toothpick inserted in the center should come out clean or with a few moist crumbs.
7. Remove from the oven and allow the cake to cool in the pan for 10 to 15 minutes before transferring it to a wire rack to cool completely.
8. Drizzle with honey or maple syrup if desired, then slice and serve.

Variations

For a slightly richer texture, you can replace 2 tablespoons of the mashed banana with 2 tablespoons of plain yogurt.

To enhance the flavor, add 1/2 teaspoon of vanilla extract to the batter.

For a lightly spiced version, mix in 1/4 teaspoon of cinnamon.

You can also fold in 2 tablespoons of finely chopped strawberries for small bursts of fruit throughout the cake.

For a gluten-free option, substitute the all-purpose flour with a 1:1 gluten-free baking flour blend.

Storage/Reheating

Store the cake in an airtight container at room temperature for up to 2 days.

For longer storage, refrigerate it in a sealed container for up to 5 days. Allow it to come to room temperature before serving for the best texture.

To freeze, wrap individual slices tightly in plastic wrap and place them in a freezer-safe container. Freeze for up to 2 months. Thaw at room temperature.

To reheat, warm a slice in the microwave for 10 to 15 seconds to restore softness.

FAQs

Can I use frozen strawberries instead of fresh?

Yes, you can use frozen strawberries. Thaw them completely and drain excess liquid before blending.

How ripe should the bananas be?

The bananas should be very ripe with brown spots. This ensures maximum sweetness and smoother texture.

Why is my cake dense?

Overmixing the batter or using underripe bananas can result in a denser texture.

Can I make this recipe vegan?

Yes, the base recipe is already vegan if you skip the honey or use maple syrup instead.

Can I turn this into muffins?

Yes, pour the batter into a lined muffin tin and bake at 350°F for about 18 to 22 minutes.

Do I need to add sugar?

No additional sugar is necessary. The bananas and strawberries provide natural sweetness.

How do I know when the cake is done?

Insert a toothpick into the center. If it comes out clean or with a few moist crumbs, it is ready.

Can I add baking powder?

This recipe is designed to be simple and dense. However, you may add 1 teaspoon of baking powder for a slightly lighter texture.

Why is my batter too thin?

If your strawberries release too much liquid, the batter may thin out. Add 1 to 2 tablespoons of flour to adjust consistency.

Can I double the recipe?

Yes, double all ingredients and bake in a 9×13-inch pan. The baking time may increase slightly, so check for doneness around 35 to 40 minutes.
