Ingredients

For the cupcakes

100g self-raising flour
25g cocoa powder, sifted
1/2 tsp baking powder
100g unsalted butter, softened
100g caster sugar
2 large eggs, room temperature
2 tbsp whole milk
1/2 tsp vanilla extract

How to Make Mary Berry Chocolate Cupcakes

Prepare the tin and oven: Preheat the oven to 180C (160C fan) and line a 12-hole muffin tin with paper cases, using around 10 of the holes.
Cream the butter and sugar: Beat the softened butter and caster sugar together until pale and fluffy, about 2 minutes with an electric mixer, as this traps air and gives a lighter sponge.
Add the eggs: Beat in the eggs one at a time, adding a spoonful of the flour with the second egg to stop the mixture curdling.
Fold in the dry ingredients: Sift the flour, cocoa powder and baking powder over the mixture, then fold in gently with a metal spoon until just combined.
Loosen the batter: Stir in the milk and vanilla extract until the mixture drops easily off the spoon; this keeps the sponge from turning dense.
Divide and bake: Spoon the batter evenly into the paper cases, filling each about two-thirds full, then bake for 18-20 minutes until well risen and springy to the touch.
Cool completely: Transfer the cupcakes to a wire rack straight after baking and leave until fully cold before icing, otherwise the buttercream will melt.
Make the buttercream: Beat the butter alone for a minute until smooth, then gradually add the icing sugar and cocoa powder, beating well between additions.
Pipe or swirl the topping: Loosen the buttercream with a little milk and vanilla extract, then pipe or spread generous swirls over each cooled cupcake.

Tips for the Best Mary Berry Chocolate Cupcakes

Why do my cupcakes sink in the middle?

This usually happens when the oven door is opened too early or the cupcakes are underbaked, so leave them undisturbed for the first 15 minutes and check they spring back before removing.

Why are my cupcakes dry instead of moist?

Overbaking is the most common cause, so start checking at 18 minutes and remove the cupcakes as soon as a skewer comes out with just a few moist crumbs.

Why did my cupcakes turn out dense instead of light?

This points to under-creaming the butter and sugar or overmixing once the flour goes in, so cream thoroughly first and fold the dry ingredients in gently.

How do I stop the cupcake cases from peeling away from the sponge?

Peeling cases usually mean the cupcakes were iced or wrapped while still slightly warm, so allow them to cool fully on a wire rack before handling.

Why is my buttercream too runny to pipe?

Runny buttercream is often down to butter that is too soft or too much milk added too quickly, so chill it for 10 minutes and add liquid a teaspoon at a time.

Serving Suggestions

Serve at room temperature so the buttercream stays soft and the sponge tastes at its best
Pair with a strong cup of tea or coffee for an afternoon treat
Dust with a little extra cocoa powder or chocolate shavings for a neat finish
Arrange on a tiered stand for birthday parties or afternoon tea gatherings
Add a few fresh raspberries on top to cut through the richness of the buttercream

Storage

Room temperature

Keep the iced cupcakes in an airtight container at room temperature for up to 2 days.

Refrigerator

Store in an airtight container in the fridge for up to 5 days, as the buttercream keeps well chilled. Bring to room temperature for about 30 minutes before serving for the best texture.

Freezing

Freeze the un-iced sponges wrapped tightly in cling film and stored in a freezer bag for up to 2 months. Defrost overnight at room temperature, then make and add the buttercream fresh before serving.

FAQs

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

Yes, use 100g plain flour with 1 1/2 tsp baking powder in place of the self-raising flour and the same amount already listed.

Can I make these cupcakes ahead of time?

Yes, bake the sponges up to 2 days ahead and store them unfrosted in an airtight container, then make the buttercream and ice them on the day you plan to serve.

Can I freeze chocolate cupcakes?

Yes, the plain sponges freeze well for up to 2 months, though it is best to freeze them without the buttercream and ice them fresh after defrosting.

What size cupcake cases work best?

Standard muffin-sized paper cases work best for this recipe, giving a good rise and an even bake within the 18-20 minute timing.

Can I double this recipe?

Yes, all quantities can be doubled to make a full batch of around 20 cupcakes, though it is best to bake in batches rather than overcrowding the oven.
