Ingredients

For the Muffins

275g self-raising flour
1 tsp baking powder
½ tsp bicarbonate of soda
100g caster sugar
3 large ripe bananas (about 300g peeled weight)
2 large eggs
75ml sunflower oil
75ml milk
1 tsp vanilla extract
150g chocolate chips (milk or dark)

Optional Topping

2 tbsp chocolate chips for sprinkling on top
1 tbsp demerara sugar for a crunchy finish

How to Make Mary Berry Banana Chocolate Chip Muffins

Prepare the oven: Preheat the oven to 200°C or 180°C fan. Line a 12-hole muffin tin with paper muffin cases. Place a shelf in the middle of the oven so the muffins bake evenly and rise with a lovely golden top.
Mash the bananas: Peel the ripe bananas and place them in a large mixing bowl. Use a fork to mash them until mostly smooth with just a few small lumps remaining. These little pieces of banana add wonderful texture to the finished muffins.
Combine the wet ingredients: Add the eggs, sunflower oil, milk, and vanilla extract to the mashed bananas. Whisk everything together until well combined and smooth. The mixture should look slightly frothy and evenly blended.
Mix the dry ingredients: In a separate large bowl, weigh out the self-raising flour, baking powder, bicarbonate of soda, and caster sugar. Give them a quick stir with a fork or whisk to distribute the raising agents evenly throughout the flour.
Combine wet and dry: Pour the banana and egg mixture into the bowl of dry ingredients. Use a large metal spoon or spatula to fold everything together gently. Stop mixing as soon as the flour is just incorporated. The batter should still look slightly lumpy. Overmixing will make the muffins tough rather than light and tender.
Fold in the chocolate chips: Scatter the 150g of chocolate chips over the batter and fold them in with just two or three gentle strokes. This keeps the chips evenly distributed without overworking the mixture.
Fill the muffin cases: Divide the batter equally among the 12 muffin cases, filling each one about three-quarters full. Use an ice cream scoop or two spoons for neat, even portions. If you are using the optional topping, scatter a few extra chocolate chips and a pinch of demerara sugar over each muffin now.
Bake the muffins: Place the tin in the preheated oven and bake for 18 to 22 minutes until the muffins are well risen, golden brown on top, and a skewer inserted into the centre comes out clean or with just a few moist crumbs. Avoid opening the oven door during the first 15 minutes to prevent the muffins from sinking.
Cool and serve: Remove the tin from the oven and let the muffins cool in the tin for 5 minutes. Then transfer them to a wire rack to cool slightly before serving. These muffins are absolutely wonderful eaten warm when the chocolate chips are still soft and melty, but they are equally delicious at room temperature.

Tips for Perfect Banana Chocolate Chip Muffins

How ripe should the bananas be?

The riper the banana, the better the muffin. Look for bananas with plenty of brown spots on the skin or even completely brown skins. These bananas are naturally sweeter, softer, and much easier to mash. They also add more moisture, which keeps the muffins incredibly tender. If your bananas are not quite ripe enough, you can speed up the process by placing them in a paper bag at room temperature for a day or two. In a pinch, you can also bake unpeeled bananas in the oven at 150°C for about 15 minutes until the skins turn black and the flesh is very soft.

Why should I avoid overmixing the batter?

Overmixing is the most common reason muffins turn out dense and chewy instead of light and fluffy. When you stir the batter too much, you develop the gluten in the flour, which creates a tough texture. The goal is to mix until the dry ingredients are just barely incorporated. A few small streaks of flour or lumps in the batter are perfectly fine and actually preferred. This gentle approach gives you that lovely, tender crumb that Mary Berry is known for.

Can I use dark chocolate instead of milk chocolate chips?

Absolutely. Dark chocolate chips work beautifully in this recipe and provide a slightly richer, more intense chocolate flavor that pairs wonderfully with the sweet banana. You can also chop a bar of good-quality dark chocolate into chunks for a more rustic look and uneven pockets of melted chocolate throughout the muffins. White chocolate chips are another lovely option if you prefer a milder, creamier sweetness.

What can I use instead of sunflower oil?

Any neutral-flavored oil works well here. Vegetable oil, rapeseed oil, or light olive oil are all suitable substitutes. You can also use melted and slightly cooled butter for a richer flavor, though the texture will be slightly different. Oil-based muffins tend to stay moist for longer than butter-based ones, which is why Mary Berry often favors oil in quick bread and muffin recipes.

How do I stop the chocolate chips from sinking to the bottom?

Tossing the chocolate chips in a tablespoon of flour before folding them into the batter can help them stay suspended throughout the muffin rather than sinking. However, with a thick banana batter like this one, sinking is rarely a major issue. The key is to fold them in at the very end with minimal stirring so they stay distributed evenly.

Serving Suggestions

Serve warm from the oven with a pat of butter and a cup of tea or coffee for a cozy breakfast or afternoon snack.
Pack into lunchboxes for a homemade treat that children and adults will love equally.
Pair with a bowl of Greek yogurt and fresh berries for a more substantial breakfast.
Serve alongside a banana milkshake or hot chocolate for the ultimate banana and chocolate combination.
Display on a cake stand as part of an afternoon tea spread alongside scones and sandwiches.
Warm a muffin slightly and serve with a scoop of vanilla ice cream for a simple dessert.

Storage

Room Temperature

Store the cooled muffins in an airtight container at room temperature for up to 2 days. They will stay soft and moist, especially if you place a sheet of kitchen paper in the bottom of the container to absorb any excess moisture. Keep them away from direct sunlight and heat sources.

Refrigerator

If your kitchen is warm or you want to extend their freshness, store the muffins in an airtight container in the refrigerator for up to 5 days. Bring them to room temperature before eating or warm them briefly in the microwave for 15 to 20 seconds to restore their soft texture.

Freezing

These banana chocolate chip muffins freeze exceptionally well. Let them cool completely, then wrap each muffin individually in cling film or place them in a freezer-safe bag. They will keep in the freezer for up to 3 months. To enjoy, thaw overnight in the refrigerator or defrost in the microwave for 30 to 40 seconds. You can also reheat them from frozen in an oven set to 160°C for about 10 minutes.

Frequently Asked Questions

Can I make these muffins without eggs?

Yes, you can replace each egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, left to sit for 5 minutes). The texture will be slightly denser but still delicious. Mashed banana already acts as a natural binder, so egg-free versions of this recipe work better than many other muffin recipes.

Can I add nuts or other mix-ins to these muffins?

Absolutely. Chopped walnuts, pecans, or hazelnuts are wonderful additions that complement the banana and chocolate flavours. You can also add desiccated coconut, dried cranberries, or a swirl of peanut butter. Just keep the total amount of mix-ins to around 200g so the batter is not overloaded.

Why did my muffins not rise properly?

Flat muffins are usually caused by expired raising agents, an oven that is not hot enough, or overmixing the batter. Always check that your baking powder and bicarbonate of soda are within their use-by dates. Make sure the oven is fully preheated before the muffins go in, and remember to mix the batter gently and briefly.

Can I use plain flour instead of self-raising flour?

Yes, use 275g plain flour and add 2½ teaspoons of baking powder along with the ½ teaspoon bicarbonate of soda already in the recipe. Sift everything together to ensure even distribution of the raising agents throughout the flour.

Can I make mini muffins with this recipe?

Yes, this batter works perfectly for mini muffins. Line a mini muffin tin with small paper cases and fill each one about three-quarters full. Reduce the baking time to 10 to 12 minutes and check for doneness with a toothpick. This recipe will make approximately 24 mini muffins.
