How to Make Mary Berry chocolate cupcakes

1. Preheat the oven to 200°C, or 180°C Fan/Gas Mark 6. Line a 12-hole muffin tin with paper cases.
2. Put the cocoa powder into a small bowl and add the boiling water. Mix until it forms a smooth, thick paste.
3. Add the softened butter, golden caster sugar, self-raising flour, eggs, and baking powder to a large mixing bowl. Add the cocoa paste and mix the ingredients with an electric hand whisk until the batter is smooth and well combined.
4. Divide the mixture equally between the paper cases. Fill each case about two-thirds to three-quarters full so the cupcakes have enough room to rise.
5. Bake for 15 minutes, or until the cupcakes are risen and springy to the touch. A skewer or cocktail stick inserted into the centre should come out clean.
6. Leave the cupcakes to cool in the tin for a few minutes. Transfer them to a wire rack and allow them to cool completely before icing.
7. Melt the dark chocolate gently and leave it to cool slightly. Beat the softened butter until smooth, then gradually sift in the icing sugar.
8. Add the melted chocolate, vanilla extract, and milk to the butter mixture. Beat until you have a smooth, creamy, and spreadable buttercream, adding a little more milk if needed.
9. Spoon the buttercream into a piping bag fitted with a star nozzle. Pipe swirls over the completely cooled cupcakes.
10. Finish with chocolate decorations or sprinkles. Allow the icing to set slightly before serving.

Expert Tips for Mary Berry chocolate cupcakes

After making chocolate cupcakes many times, I find that careful measuring and gentle mixing make the biggest difference. These cupcakes are simple, but a few small details help keep them light, evenly baked, and easy to decorate. Pay particular attention to the butter temperature, oven heat, and baking time.

• Use muffin cases if you prefer a deeper cupcake with a taller appearance.
• An ice cream scoop is useful for dividing the batter evenly between the cases. This helps all the cupcakes bake at the same rate.
• Make sure the butter is properly softened before mixing. Cold butter can make the batter harder to combine smoothly.
• Avoid overmixing once the ingredients are combined. Too much mixing can make the finished cupcakes heavier rather than light and tender.
• Keep the oven door closed while the cupcakes are baking. Check them around 15 minutes, or slightly earlier if your oven runs hot.
• Test the cupcakes with a skewer before removing them from the oven. If it comes out clean and the tops feel springy, they are ready.
• For a richer chocolate flavour, use good-quality melted dark chocolate in the buttercream. Allow it to cool slightly before adding it to the butter mixture.
• If piping feels tricky, spread the butter icing over the cupcakes with a small palette knife instead. This is also an easy option when baking with younger children.
• For a simpler one-bowl version, the ingredients can be added in any order and mixed until smooth, making the preparation less messy.
• For a plain butter icing, omit the cocoa powder from the sponge and use the same basic buttercream method. If the icing becomes too thick, gradually add a little milk until it reaches the desired consistency.

FAQs

Q: How do I decorate chocolate cupcakes?

Once the cupcakes are completely cool, fill a piping bag with chocolate buttercream and fit it with a star nozzle. Pipe the icing using a gentle spiral motion, then add chocolate decorations, sprinkles, or seasonal toppings.

Q: Do you have to use chocolate buttercream?

No. You can use plain butter icing if you prefer a lighter topping. Vanilla buttercream also works well with the chocolate sponge.

Q: Can I make these cupcakes extra chocolatey?

Yes. Add a small amount of chocolate chips to the batter for extra chocolate flavour and texture. You can also use melted dark chocolate in the buttercream.

Q: Why are my cupcakes dry?

The most common reason is overbaking. Measure the ingredients carefully and remove the cupcakes when a skewer comes out clean and the sponge feels springy.

Q: Why did my cupcakes sink?

Opening the oven door too early can cause cupcakes to sink before the sponge has set. Too much baking powder or overmixing the batter can also affect the final texture.

Q: Can I make these cupcakes ahead of time?

Yes. You can bake the cupcakes a day ahead and keep them in an airtight container at room temperature. Decorate them with buttercream shortly before serving.

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

Yes. For every 100 g of self-raising flour, use 100 g plain flour with about 2 teaspoons baking powder. Sift the flour and baking powder together before adding them to the mixture.

Q: Can I make these cupcakes gluten-free?

Yes. Replace the self-raising flour with a gluten-free self-raising flour blend suitable for cakes. Check that all other ingredients and decorations are also labelled gluten-free.
