Vanilla Cupcakes Recipe UK: Soft, Simple and Reliable

These vanilla cupcakes are light, tender little cakes made with butter, caster sugar, eggs and self-raising flour, then finished with a smooth vanilla buttercream. This straightforward UK-style recipe makes a dozen cupcakes, with familiar ingredients and clear cues for mixing, baking and decorating.

Ingredients

12 standard paper cupcake cases
½ cup plus 1 tablespoon (125 g) unsalted butter, softened, for the cakes
⅔ cup (130 g) caster sugar
2 large eggs, at room temperature
1 cup (125 g) self-raising flour
2 tablespoons (30 ml) whole milk
2 teaspoons (10 ml) vanilla extract, divided: 1½ teaspoons (7.5 ml) for the cakes and ½ teaspoon (2.5 ml) for the icing
A small pinch (about 0.5 g) fine salt
⅔ cup (150 g) unsalted butter, softened, for the buttercream
2½ cups (300 g) icing sugar, sifted
1 tablespoon (15 ml) milk or cream, plus up to 1 tablespoon (15 ml) more if needed for the icing

Instructions

Prepare the tin and oven. Set a rack in the centre of the oven and preheat it to 350°F (180°C), or 320°F (160°C) for a fan oven. Line a 12-hole standard muffin tin with paper cases. Let the butter soften until it gives slightly when pressed but is not oily or melted. Starting with room-temperature butter and eggs helps the batter combine evenly.
Cream the butter and sugar. In a mixing bowl, beat the 125 g butter and caster sugar with an electric mixer on medium speed for about 3 minutes, scraping the bowl once. The mixture should look paler and a little fluffy. A hand whisk and a sturdy bowl work too, though they take more effort. Avoid beating so long that the butter becomes warm and greasy.
Add the eggs and vanilla. Beat in the eggs one at a time, mixing just until each is incorporated. If the mixture looks slightly curdled, add a spoonful of the measured flour and continue; it will usually come back together when the remaining flour is added. Mix in 1½ teaspoons vanilla extract.
Fold in the flour and milk. Add the self-raising flour and salt. Fold gently with a spatula, adding the 2 tablespoons milk as you go, until no dry flour remains. Stop as soon as the batter is smooth. It should fall slowly from the spatula; if it is unusually stiff, mix in another teaspoon of milk. Overmixing at this stage can make the cakes less tender.
Divide the batter. Spoon the batter evenly among the 12 cases, filling each about two-thirds full. A level ice-cream scoop or two spoons makes portioning easier. Keep the cases similar in size so the cupcakes bake at the same rate, and wipe away any drips on the tin before it goes in the oven.
Bake until risen and set. Bake for 18–20 minutes, until the tops are lightly golden, spring back when gently pressed and a skewer inserted into the centre comes out clean or with a few dry crumbs. Because the batter contains eggs, check the centre of a cupcake with a clean food thermometer; USDA FSIS lists 160°F (71°C) as the safe minimum internal temperature for egg dishes. Avoid opening the oven during the first 15 minutes, as a sudden drop in temperature can affect the rise.
Cool completely. Leave the cupcakes in the tin for 5 minutes, then transfer them to a wire rack and cool for at least 40 more minutes before icing. The cakes need to be cool all the way through: buttercream placed on warm cupcakes will soften, slide or melt. Use this cooling time to make the icing.
Make the buttercream. Beat the 150 g softened butter for 2–3 minutes until creamy. Add the sifted icing sugar in two or three additions, mixing on low at first to prevent a cloud of sugar, then beat in ½ teaspoon vanilla and 1 tablespoon milk. Continue beating for 2 minutes. Add the extra milk a teaspoon at a time if needed; the icing should hold a soft peak and be easy to spread or pipe.
Finish the cupcakes. Spread the buttercream on with a small palette knife, or pipe it onto the fully cooled cakes. Allow about 10–15 minutes for finishing the batch. Add sprinkles while the icing is still soft if using them, then serve.

Tips

Measure flour carefully. Spoon flour into a cup and level it rather than scooping and packing it; a packed cup can contain too much flour and make the crumb dry. Weighing the ingredients in grams is the most reliable option. If your self-raising flour has been open for a long time, check the date and replace it if it has lost freshness.
Use a practical US flour substitute. If self-raising flour is unavailable, use 1 cup (125 g) plain or all-purpose flour mixed with 1½ teaspoons (6 g) baking powder and the pinch of salt. This gives the batter the lift it needs. Do not add that extra baking powder if you are already using self-raising flour.
Bring cold ingredients towards room temperature. If you forgot to take the eggs out, place them in warm—not hot—water for about 10 minutes. Cut cold butter into small cubes and leave it to soften; do not microwave it until it melts. A batter made with ingredients at similar temperatures is less likely to split.
Watch the mixing and baking. Fold in the flour only until it disappears, and begin checking the cakes at 18 minutes because ovens vary. A skewer with wet batter means they need longer; a few crumbs are fine. Overbaking is a common reason for dry cupcakes, so take them out once they are risen and set.

Serving Suggestions

Serve the cupcakes at room temperature so the sponge feels soft and the buttercream is easy to enjoy. They are suitable for a birthday table, afternoon tea, bake sale or simple dessert; arrange them on a plate or cake stand just before serving. A cup of tea or coffee is a natural partner, while cold milk works well for children and anyone who prefers a non-caffeinated drink.

For a neat finish, pipe a modest swirl of buttercream and add a few sprinkles, a little grated white chocolate or a small piece of fresh fruit just before serving. If you are making a mixed dessert spread, keep the decoration simple so the vanilla flavour remains clear. These cakes are sweet enough to serve on their own, so extra sauce or cream is optional rather than necessary.

Variations

Make lemon cupcakes: Add the finely grated zest of 1 unwaxed lemon to the butter and sugar, and use lemon juice instead of 1 teaspoon of the milk. The zest gives a fragrant citrus note without changing the basic method. For a matching topping, add a little lemon zest to the buttercream and taste before adding more liquid.

Add chocolate chips: Fold ⅓ cup (55 g) chocolate chips into the finished batter just before dividing it between the cases. Tossing the chips with a teaspoon of flour can help them stay distributed, though it is not essential. The cupcakes may need an extra minute or two; use the same doneness checks rather than relying only on the clock.

Fill the centres: Once the cakes are completely cool, cut a small cone from the centre of each cupcake and add about 1 teaspoon (5 ml) of jam or lemon curd. Replace a little of the sponge, then ice as usual. A thick filling is easier to handle than a runny one; avoid overfilling, which can make the top difficult to cover.

Try a different topping: Use a thin layer of vanilla icing made with icing sugar and a little water or milk if you prefer a lighter finish to buttercream. It will be less rich and will set with a smooth, slightly crisp surface rather than a fluffy swirl. For a simple uniced version, dust the cooled cakes lightly with icing sugar just before serving.

Storage and Reheating

Keep iced cupcakes in a single layer in an airtight container at cool room temperature for up to 2 days. If your room is warm, or the buttercream contains a perishable addition such as fresh fruit, refrigerate them instead. Refrigerate the cupcakes within 2 hours of baking or serving. In the refrigerator, they keep for up to 4 days; the sponge may feel firmer when cold, so bring them back to room temperature for about 30–45 minutes before serving.

For longer storage, freeze the cupcakes for up to 2 months. Freeze them in a sealed container, ideally uniced so the topping keeps its texture; thaw overnight in the refrigerator or for a few hours at room temperature, then decorate. Iced cupcakes can also be frozen, but set them uncovered in the freezer until the buttercream is firm before packing carefully. These cakes are best served at room temperature rather than reheated, which can melt the buttercream and dry the sponge.

Frequently Asked Questions

Why did my cupcakes sink in the middle?
A sunken centre can mean the cakes were underbaked, the oven door was opened too early, or the batter was overmixed after adding the flour. Check that your oven is fully preheated, avoid opening it during the first 15 minutes and use a skewer or thermometer to confirm the centres are baked through. Also check that your self-raising flour is fresh.

Can I make these without an electric mixer?
Yes. Use a wooden spoon or sturdy whisk to beat the softened butter and sugar until noticeably lighter, then add the eggs one at a time. Fold in the flour by hand with a spatula. The process will take a little longer, but gentle mixing once the flour is added is still important for a soft crumb.

Can I make the cupcakes ahead?
Yes. Bake the cakes a day ahead, cool them completely and store them in an airtight container. Make the buttercream on the day you plan to serve them, or refrigerate it in a covered bowl for up to 3 days and let it soften before re-whipping. Allow time for the cakes to cool fully before decorating.

How do I stop the buttercream from being too runny?
Start with softened, not melted, butter and add the milk gradually. If the icing is too loose, beat in more sifted icing sugar a tablespoon at a time, then chill it briefly if the room is warm. If it is too stiff to pipe, add milk in small increments. Temperature and the exact butter brand can affect consistency.

Can I use salted butter?
Yes. Use the same weight of salted butter and leave out the pinch of salt in the cake batter. Salt levels vary between brands, so taste the buttercream before adding any extra salt. Unsalted butter gives you more control over the final flavour, but salted butter works well in this recipe.

What is the best way to tell when they are baked?
The tops should spring back when gently pressed, and a skewer from the centre should come out clean or with a few dry crumbs rather than wet batter. A thermometer inserted into the centre of a cupcake should meet the egg-dish safe minimum stated in the instructions. Start checking at 18 minutes because case size and oven performance can change the baking time.
