Step-by-Step Guide to Making Mary Berry Carrot and Banana Cake

• Prepare the tin – Line and grease a 20cm cake tin to prevent sticking.
• Mix the wet ingredients – Whisk 2 eggs, 2 mashed bananas, 100ml oil, and 1 tsp vanilla until smooth.

• Add carrots – Fold in 150g grated carrots, coating them lightly with the dry mix.
• Combine everything – Pour the wet mixture into the dry ingredients and fold gently until just combined.
• Add extras (optional) – Stir in walnuts or raisins for added texture.
• Bake the cake – Transfer batter to the tin and bake at 170°C (340°F) for 40–45 minutes, or until a skewer comes out clean.

What I Got Wrong (And How I Fixed It)

• Cake turned dense – Mixing too vigorously deflated the batter; gentle folding kept it light.
• Frosting became runny – Ensured cream cheese and butter were cold before beating.
• Carrots clumped together – Tossed them in flour first to distribute evenly.
• Banana flavour too weak – Used very ripe bananas and increased to two for a stronger taste.

FAQs

Why did my carrot and banana cake turn out dense instead of soft?

A dense cake usually means the batter was overmixed after adding the flour. Mix gently until just combined, and ensure the bananas are very ripe so they blend smoothly into the mixture, helping the cake rise properly.

How do I keep the carrot and banana cake moist for several days?

The natural moisture from bananas and grated carrots keeps this cake soft, but storing it in an airtight container is key. Brushing the warm cake with a little syrup or covering it with cream cheese frosting also helps retain moisture.

Why did my cream cheese frosting become runny?

Cream cheese frosting becomes runny when the butter or cream cheese is too warm. Use both ingredients straight from the fridge and beat only until smooth. Adding more icing sugar can help firm it up if needed.

Should I grate the carrots finely or coarsely for the best texture?

Finely grated carrots work best because they blend evenly into the batter and keep the crumb soft. Coarse grating may cause uneven pockets of carrot that affect texture and moisture distribution.

Wrapping It Up

Mary Berry Carrot and Banana Cake is a wonderfully moist and flavourful bake that blends simplicity with richness. With bananas, carrots, warm spices, and a silky cream cheese frosting, this cake brings warmth and comfort to any occasion.
