Preparations Before You Start

Before I even crack an egg, I like to get everything ready so the whole bake runs smoothly. Turn your oven on first and set it to 180°C, or 160°C if you’ve got a fan oven, 350°F, or Gas Mark 4.

Give it time to reach full heat while you prepare your tin. Take a 20 x 9cm loaf tin and grease it lightly with butter, working it into the corners and along the base. Then line the tin with non-stick baking parchment, leaving paper hanging over the two long sides.

Those overhangs become handles later, so you can lift your loaf out cleanly once it’s cooled, without wrestling it out or damaging the sides.

Mary Berry Banana Bread Ingredients

2 ripe bananas, mashed – The riper and more speckled, the better. Overripe bananas give natural sweetness and a proper depth of flavour, so don’t rush out for fresh ones when spotty bananas do a far better job here.

175g caster sugar – Tate & Lyle caster sugar works a treat here. It dissolves smoothly into the mix and gives the loaf its light sweetness without turning the crumb heavy or gritty.

100g butter, softened – I always reach for Lurpak or Anchor. Softened butter creams into the mix easily and gives the loaf its rich, rounded flavour that margarine simply can’t match.

2 large eggs – Free-range eggs give the best colour and flavour. They bind everything together and help the loaf rise into that lovely domed top we all want.

225g self-raising flour – Allinson’s or Homepride self-raising flour gives a reliable rise. It already contains raising agents, so your loaf lifts nicely without extra faff or guesswork.

1 tsp baking powder – This gives the loaf that little extra lift alongside the self-raising flour, helping it rise evenly and avoid a dense, heavy centre.

2 tbsp milk – Any full-fat milk from your fridge works fine. It loosens the batter just enough so it drops easily from the spoon rather than sitting stiff and thick.

Ingredient Notes & Smart Substitutions

Bananas: The darker the bananas, the better the flavour. If yours are not quite ripe, leave them for another day before baking.

Butter: Salted butter can be used if that’s all you have. It gives a slightly richer taste.

Caster Sugar: Light brown soft sugar can replace caster sugar if you prefer a deeper, caramel-like flavour. The loaf will be a little darker.

Self-Raising Flour: If you only have plain flour, add 2 teaspoons of baking powder for every 225g of flour.
Milk: Semi-skimmed, whole milk, or even a dairy-free milk such as oat milk all work well.

Gluten-Free Option: Use a good-quality gluten-free self-raising flour blend. If it does not already contain xanthan gum, add it following the packet instructions.

Equipment You’ll Need to Make This Banana Bread

20 x 9cm Loaf Tin: A standard loaf tin that provides the ideal shape and even heat distribution, helping the banana bread bake evenly with consistent results.

Non-stick Baking Parchment: Prevents the loaf from sticking to the tin while making removal easier after baking, keeping the finished loaf intact and neat.

Large Mixing Bowl: A spacious bowl that allows all ingredients to be combined comfortably, reducing spills and making mixing easier and more efficient.

Wooden Spoon or Electric Hand Mixer: Use a wooden spoon for controlled hand mixing or an electric hand mixer for quicker blending into a smooth batter.

Spatula: Ideal for scraping every bit of batter from the bowl, spreading it evenly in the tin, and smoothing the surface before baking.

Wire Cooling Rack: Allows air to circulate around the loaf as it cools, preventing a soggy bottom and helping maintain the perfect texture.

Skewer or Cake Tester: Insert into the centre of the loaf to check doneness. A clean skewer indicates the banana bread is fully baked and ready.

How To Make Banana Bread like Mary Berry

Step 01 – Prepare the Loaf Tin

Lightly grease the inside of a 20 x 9cm loaf tin with butter. Line it with non-stick baking parchment, allowing the paper to extend above the sides of the tin. The butter helps keep the parchment in place while the overhanging paper creates convenient handles for lifting the finished loaf out after cooling.

Step 02 – Combine the Ingredients

Place the mashed ripe bananas into a large mixing bowl. Add the caster sugar, softened butter, eggs, self-raising flour, baking powder and milk. This is an all-in-one method, so all of the ingredients go into the bowl together before mixing.

Step 03 – Mix the Batter

Using a wooden spoon or an electric hand mixer, mix everything together for about 2 minutes until the batter is smooth and evenly combined. If mixing by hand, scrape around the sides and bottom of the bowl regularly to ensure all of the flour and butter are fully incorporated. The batter is ready when it drops easily from the spoon in a thick ribbon.

Step 04 – Fill the Tin

Spoon the batter into the prepared loaf tin. Spread it evenly with the back of a spoon or a spatula, making sure the mixture reaches all four corners. Smooth the surface to encourage even baking.

Step 05 – Bake the Banana Loaf

Place the tin in the preheated oven and bake for about 1 hour, or until the loaf has risen well and developed a rich golden-brown colour. Baking times may vary slightly depending on your oven.

Step 06 – Check for Doneness

Insert a skewer or cake tester into the centre of the loaf. If it comes out clean, with no wet batter attached, the banana loaf is fully baked. If necessary, continue baking for a few more minutes and test again.

Step 07 – Cool the Loaf

Leave the loaf to cool in the tin for a short time before transferring it to a wire rack. Once cool enough to handle, use the overhanging baking parchment to lift the loaf out of the tin without damaging its shape.

Step 08 – Slice and Serve

Once completely cooled, slice the banana loaf with a sharp serrated knife. The finished loaf should have a moist, tender crumb with a soft banana flavour and a lightly golden crust. Serve as it is or with a little butter if preferred.

Chef Tips & Notes for Perfect Mary Berry Style Banana Bread

• Always use very ripe bananas with brown spots for the sweetest flavour.
• Take the butter and eggs out of the fridge before baking so they mix more easily.
• Mix the batter only until smooth. Too much mixing can make the loaf heavy.
• Check your loaf a few minutes before the full baking time if your oven cooks quickly.
• Let the bread cool before slicing. Warm banana bread is lovely, but cutting it too early can make it crumble.
• Leave the loaf wrapped in its baking parchment after cooling if you plan to store it. It helps keep the crumb soft.
• Use a serrated bread knife for cleaner slices without squashing the loaf.

Variations You Can Try

Chocolate Chip Banana Bread

Fold 100g of milk or dark chocolate chips into the batter before baking. They melt into little pockets of chocolate and make each slice feel like a special treat.

Walnut Banana Bread

Stir in 75g chopped walnuts for a bit of crunch. The nuts add a lovely texture and go really well with the sweet banana flavour.

Cinnamon Banana Bread

Mix 1 teaspoon of ground cinnamon into the flour before combining everything together. It gives the loaf a warm, cosy taste that is perfect with a cup of tea.

Mixed Berry Banana Bread

Gently fold a handful of fresh or frozen blueberries into the batter. They add little bursts of fruit without changing the simple feel of the recipe.

Gluten-Free Banana Bread

Swap the self-raising flour for a good-quality gluten-free self-raising flour blend. If the blend does not already include xanthan gum, add it following the packet instructions. The loaf still comes out soft and full of flavour.

Serving Ideas With This Banana Bread

Slice it thick and serve it warm with a scrape of salted butter melting into the crumb. A drizzle of honey works well for something sweeter, while a spread of soft cheese gives a lovely tangy contrast.

Some people like it lightly toasted the next day, which brings out a nutty edge on the crust and warms the kitchen with a proper homely smell. It pairs beautifully with a strong pot of tea or a milky coffee, and it also works well packed into a lunchbox for later in the day.

For a proper treat, add a spoonful of clotted cream on the side, or a dollop of custard if you’re serving it as a pudding after dinner.

Mistakes That Will Ruin Banana Bread (and How to Avoid Them)

Using firm yellow bananas – Wait until they are well spotted. Ripe bananas give much better flavour and moisture.

Mixing for too long – Stop as soon as the batter is smooth. Overmixing makes the loaf heavy.

Skipping the baking parchment – It can make the loaf difficult to remove from the tin.

Opening the oven too early – Leave the door closed for at least the first 45 minutes so the loaf rises properly.

Not testing the centre – Always use a skewer before taking the loaf out of the oven.

Cutting it while it’s hot – Let it cool first so the slices hold together neatly.

Make-Ahead & Storing Leftover

One thing I really like about this loaf is that it keeps well, so I often bake it a day before I need it. Once it has cooled completely, wrap it tightly in its baking parchment or baking paper, then add a layer of cling film or place it in an airtight container. It will stay fresh at room temperature for up to 4 days.

If you want to keep it for longer, slice the loaf first and freeze the slices in a freezer-safe bag or container. They will keep well for up to 3 months. I place a small piece of baking paper between each slice, so I can take out only what I need. Leave the slices to thaw at room temperature, or warm them gently in the microwave for a few seconds before serving.

FAQs

Can I use frozen bananas for this recipe?

Yes, you can. I often freeze very ripe bananas instead of throwing them away. Let them thaw fully before using them, then pour away any extra liquid if there is too much. Mash them well and use them exactly as you would fresh ripe bananas. They give the loaf plenty of flavour and help keep it moist.

How do I know when the banana bread is fully baked?

The easiest way is to insert a skewer or cake tester into the middle of the loaf. If it comes out clean or with just a few dry crumbs, the loaf is ready. If you see wet batter, bake it for another five minutes and test again. The top should also be golden brown and feel firm when lightly pressed.

Why did my banana bread sink in the middle?

This usually happens when the loaf is underbaked or the oven door is opened too early. Too much mixing can also affect the texture. I always bake until the centre is fully cooked and avoid opening the oven during the first part of baking. That helps the loaf keep its shape.

Can I make this recipe without an electric mixer?

Absolutely. I often use a simple wooden spoon when I want a relaxed baking session. It only takes a couple of minutes to bring everything together. Just make sure you scrape the sides and bottom of the bowl so all the flour is mixed in evenly.

Can I reduce the amount of sugar?

Yes, but keep in mind that sugar adds more than sweetness. It also helps the loaf stay soft. You can reduce it slightly if your bananas are very ripe, but taking away too much may change the texture and make the bread less moist.

Can I add nuts or chocolate chips to this recipe?

Yes, and I do it quite often when I want a small change. Fold about 75–100g of chopped walnuts, pecans, or chocolate chips into the batter after mixing. Stir them in gently so they are spread through the loaf. The recipe still bakes well and you get a little extra texture or sweetness in every slice.

Why is my banana bread dry?

Dry banana bread is usually caused by baking it for too long or using bananas that are not ripe enough. Measuring the flour carefully also makes a big difference. Too much flour can make the loaf heavy and dry. I always use very ripe bananas and check the loaf with a skewer a few minutes before the baking time ends.

I hope you enjoy making this Mary Berry Banana Bread Recipe as much as I do. It is one of those bakes that never feels complicated, yet the result is always soft, moist, and full of lovely banana flavour. You only need a handful of everyday ingredients and a little time to create a loaf that everyone will happily slice into.
