The bananas are the heart of this cake—ripe ones (with brown spots) pack the most natural sweetness and moisture. Costco or Trader Joe’s often have perfect bananas at the right stage, but your local grocery store’s produce section works too. Look for ones that yield slightly to gentle pressure. The butter should be softened but not melted—Mary Berry’s method relies on that perfect texture for a tender crumb. If your kitchen runs warm, chill the butter for 10 minutes before measuring. For the flour, King Arthur or Gold Medal brands are my go-to—they’re reliable for that perfect rise.
No ripe bananas? Overripe ones work best—the browner, the better. Short on milk? Almond or oat milk works in a pinch, though the texture will be slightly different. The vanilla extract matters here—pure Madagascar bourbon vanilla elevates the flavor, but imitation vanilla is fine if that’s what you’ve got. For the cinnamon, ground is easiest, but if you have whole cinnamon sticks, toast and grind them for a deeper aroma. The powdered sugar can be swapped for confectioners’ sugar—just make sure it’s finely ground. If your cake batter seems too thick, add 1-2 tbsp more milk until it reaches a smooth consistency.
This cake keeps beautifully—wrapped in plastic wrap at room temperature for 2-3 days or in the fridge for up to 5 days. For longer storage, slice and freeze portions for up to 3 months. The golden crust stays crackly if you let the cake cool completely before slicing. Mary Berry’s trick for extra moisture? Brush the warm cake with a simple syrup (equal parts sugar and water, heated until dissolved) before serving. It’s a game-changer for that restaurant-quality finish.

Step-by-step instructions for Mary Berry's banana cake
Here's how to create a perfectly moist banana cake with a golden crust—every layer just as Mary Berry would make it.
👨🍳 Step 1: Prepare the Banana Mixture
Start by mashing the 3 whole ripe bananas until completely smooth—no lumps allowed. I press them through a sieve for extra silkiness, which prevents a dense texture later. In a large mixing bowl, combine the mashed bananas with the 0.75 cup softened unsalted butter and 1.5 cups granulated sugar. Beat with an electric mixer on medium speed for 2-3 minutes until the mixture is light and fluffy.
This step is crucial for incorporating air into the batter, which helps create that signature tender crumb. The butter should be soft enough to mix easily but not melted—you should still be able to press your finger into it and leave a slight indent. If your kitchen is warm, chill the butter for 10 minutes before starting to ensure proper consistency.
👨🍳 Step 2: Combine Wet Ingredients
Add the 2 whole large eggs one at a time, mixing well after each addition. Then stir in the 1 tsp vanilla extract and 0.5 cup milk. The mixture should be smooth and slightly thick. In a separate bowl, whisk together the 2 cups all-purpose flour, 1 tsp baking soda, 1 tsp ground cinnamon, 0.5 tsp salt, and the 0.25 cup powdered sugar. Sift the dry ingredients directly into the wet mixture to prevent clumping.
I fold the dry ingredients into the wet mixture using a spatula, being careful not to overmix. Overmixing develops gluten, which can make the cake tough. Stop mixing as soon as the batter comes together—you should still see a few streaks of flour. The batter will be thick but smooth, like a rich chocolate cake batter.
🔥 Step 3: Bake to Golden Perfection
Preheat your oven to 350°F and grease an 8-inch round cake pan or line it with parchment paper. Pour the batter into the prepared pan and smooth the top with a spatula. Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean with just a few moist crumbs clinging to it. The edges should be golden brown, and the top should spring back when gently pressed.
Here's the thing—banana cakes can dry out easily, so I recommend checking for doneness at the 30-minute mark. If the top is browning too quickly, tent the cake with aluminum foil to prevent over-browning while it continues to cook through. The cake is done when it's fully set but still moist—this ensures that perfect tender crumb we're after.
⏰ Step 4: Cool and Serve
Remove the cake from the oven and let it cool in the pan for 10 minutes. Then transfer it to a wire rack to cool completely. This gradual cooling prevents the cake from developing a crack in the center, which is a common issue with banana cakes. Once fully cooled, dust the top with an additional 1-2 tablespoons of powdered sugar if desired for a sweet finish.
The cake should be moist with a tender crumb and a slightly crisp golden crust. Slice it into 4 equal servings and enjoy it warm or at room temperature. I like to serve it with a dollop of whipped cream or a scoop of vanilla ice cream—it's the perfect balance of spiced banana flavor and sweetness. Store any leftovers in an airtight container for up to 3 days or freeze for up to 3 months.
Pro Tips For Making Banana Cake Recipe Mary Berry
- Mash Bananas Thoroughly: Don’t just chop them—squish those bananas until they’re smooth as pudding. The more you work them, the moister and richer the cake will be. I used to skip this, and the texture ended up dense and uneven.
- Use Room-Temp Butter: Take the butter out of the fridge 30 minutes before you start. Cold butter makes the batter fight you—it won’t creame properly with the sugar, and the cake turns out greasy instead of tender. Trust me, your mixing arm will thank you.
- Skip Overmixing the Batter: Once the flour hits the wet ingredients, stir just until combined—no more. Overmixing develops gluten, and that’s how you end up with a chewy, dense brick instead of a light, fluffy cake. Fold in the dry stuff like you’re tucking in a baby blanket.
- Test Doneness with a Slice: The toothpick trick is fine, but I swear by cutting a small slice to check—if it’s set but still slightly springy, it’s done. Overbaking dries out the cake faster than you can say “Mary Berry.” Pull it when the edges lift but the center still has a tiny wobble.
Common mistakes when making this dish
Overmixing the Batter
This is the #1 mistake I see with banana cakes—overmixing develops gluten, leading to a tough, dense texture instead of that light, tender crumb we want. Mary Berry’s method relies on a gentle fold until just combined. I stop mixing when I see a few streaks of flour remaining—no need for a perfectly smooth batter. Use a spatula for folding to avoid overworking the batter. 💛
Underripe Bananas
Using underripe bananas (firm, no brown spots) means your cake will be less sweet and more dense. The natural sugars in ripe bananas caramelize during baking, creating that signature moist texture. Look for bananas with soft spots and brown speckles—these are perfect. If you only have firm bananas, let them sit at room temperature for 24 hours to ripen faster.
Skipping the Sieve
Mashing bananas with lumps can create a grainy texture in your cake. I always press the mashed bananas through a fine-mesh sieve to remove any fibrous bits. This ensures a silky-smooth batter that bakes up light and even. If you don’t have a sieve, blend the mashed bananas for 10-15 seconds to break down any remaining chunks.
Incorrect Butter Temperature
Butter that’s too soft or melted will make your cake greasy, while too firm butter won’t mix properly. The ideal consistency is softened but still holding its shape—you should be able to press your finger into it and leave a slight indent. If your kitchen is warm, chill the butter for 10 minutes before measuring. I use Land O’Lakes unsalted butter for consistency, but any good-quality brand works.
Overbaking or Underbaking
Banana cakes are tricky—overbaking dries them out, while underbaking leaves them gummy. The toothpick test is key: insert it into the center, and it should come out with just a few moist crumbs (not wet batter, not dry crumbs). I check at 30 minutes and tent with foil if the top browns too quickly. The cake is done when it’s fully set but still moist—this ensures that perfect tender crumb.
Ignoring the Cooling Phase
Transferring the cake to a wire rack too soon can cause it to crack in the center or lose its structure. Let it cool in the pan for 10 minutes first, then transfer. This gradual cooling also helps the moisture distribute evenly. I’ve seen cakes develop ugly sinkholes when rushed—patience pays off here! 🍌

Frequently asked questions
Can I substitute regular sugar for brown sugar in this recipe?
Yes, but there’s a slight trade-off. The recipe calls for granulated sugar to keep the cake light and tender, but you can replace up to half with light brown sugar for deeper caramel notes. Just reduce any other liquid (like milk) by 1-2 tablespoons since brown sugar absorbs moisture. For best results, stick with the original recipe—Mary Berry’s version relies on that balanced sweetness for the perfect texture.
Why does my banana cake turn out dense instead of moist?
Most likely, you used underripe bananas or overmixed the batter. Ripe bananas (with brown spots) are key—they caramelize beautifully for moisture. Also, fold in the dry ingredients just until combined (stop when you see a few flour streaks). Overmixing develops gluten, making the cake tough. For extra tenderness, press the mashed bananas through a sieve to remove fibrous bits.
How do I make this cake extra moist for guests?
Mary Berry’s secret is a simple syrup glaze! After baking, brush the warm cake with 2 tablespoons sugar + 2 tablespoons water (heated until dissolved). Let it soak in for 5 minutes before serving. For even more moisture, add 1 tablespoon yogurt or sour cream to the batter—it keeps the crumb ultra-tender. Store leftovers in an airtight container with a slice of bread to absorb excess dryness.
Can I bake this in a different pan size?
but adjust the baking time. For a 9-inch round pan, reduce oven temperature to 325°F and bake for 30-35 minutes. A loaf pan (8x4 inches) works too—bake at 350°F for 45-50 minutes. The key is to check doneness with a toothpick. Smaller pans may need slightly less time, while larger ones require more. Always grease or line the pan to prevent sticking.
What’s the best way to reheat sliced banana cake?
For maximum moisture, reheat slices in the microwave for 10-15 seconds or wrap them in foil and warm in a 200°F oven for 5 minutes**. Avoid high heat—it dries out the cake. If serving cold, let slices sit at room temperature for 10 minutes first. For a restaurant-style touch, dust with powdered sugar or drizzle with warm caramel sauce before serving.
