Hairy Bikers Blueberry Mini Loaf Cakes Recipe

These blueberry mini loaf cakes have a tender, buttery crumb, bursts of juicy berries, and a hint of lemon. They are easy enough for a beginner and make a lovely addition to an afternoon tea or a lunchbox. Inspired by the comforting style of British home baking, this version takes about 1 hour, including cooling time.d lightly sweet, with golden edges and pockets of blueberries throughout. Lemon zest lifts the flavour without overpowering the fruit, while a simple lemon glaze adds a tangy finish. Leave the glaze off if you prefer a less sweet cake.

Ingredients

For the Mini Loaf Cakes

• 150g unsalted butter, softened, plus extra for greasing
• 150g caster sugar
• 2 large eggs, at room temperature
• 150g self-raising flour
• ½ teaspoon baking powder
• 2 tablespoons milk
• Finely grated zest of 1 lemon
• 150g blueberries, fresh or frozen

For the Optional Lemon Glaze

• 40g icing sugar, sifted
• 2–3 teaspoons lemon juice

Kitchen Equipment

• 8 mini loaf moulds, each with a capacity of about 150ml
• Large mixing bowl and electric mixer or wooden spoon
• Spatula, measuring spoons, and kitchen scales
• Wire cooling rack

How to Make Blueberry Mini Loaf Cakes

• Prepare the oven: Preheat the oven to 180°C conventional or 160°C fan. Place a shelf in the middle of the oven. Grease 8 mini loaf moulds and line their bases with small strips of baking parchment, or use paper mini loaf cases.
• Cream the butter and sugar: Put the softened butter and caster sugar in a large bowl. Beat for 2–3 minutes until pale and fluffy, scraping down the sides of the bowl as needed.
• Add the eggs: Beat in the eggs one at a time. If the mixture looks curdled, stir in a spoonful of the measured flour before adding the remaining egg.
• Finish the batter: Fold in the self-raising flour and baking powder, followed by the milk and lemon zest. Stop mixing as soon as no dry flour remains.
• Add the blueberries: Gently fold in the blueberries, keeping a few aside for the tops if you like. If using frozen berries, add them straight from the freezer.
• Fill and bake: Divide the batter evenly among the moulds, filling each no more than about two-thirds full. Scatter the reserved berries over the tops. Bake for 22–28 minutes, until golden and a skewer inserted into the cake comes out clean or with a few moist crumbs.
• Cool the cakes: Leave the cakes in their moulds for 10 minutes, then carefully transfer them to a wire rack. Let them cool completely before glazing.
• Make the glaze and finish: Mix the icing sugar with 2 teaspoons lemon juice, adding the remaining juice a little at a time until the glaze is thick but pourable. Drizzle over the cooled cakes and leave to set before serving.

Tips for the Best Blueberry Mini Loaf Cakes

How do I stop the blueberries from sinking?

Make sure the batter is thick enough to hold the berries and fold them in gently. You can also toss the berries with a teaspoon of the measured flour before adding them. Reserving a few for the tops helps distribute the fruit evenly.

Why are my mini loaf cakes dense?

Butter that is too cold can be difficult to cream properly, so let it soften before you begin. Once the flour is added, fold just until combined. Too much mixing can make the cakes firm rather than tender.

How can I tell when the cakes are baked?

The tops should be golden and spring back lightly when touched. Insert a skewer into the cake rather than a blueberry. It should come out clean or with a few moist crumbs, not wet batter.

What if my mini loaf moulds are a different size?

Fill the moulds no more than two-thirds full and place any extra batter in a lined muffin tin. Smaller cakes may bake sooner, while larger moulds may take longer, so start checking a few minutes early.

Serving Suggestions

• Serve with a cup of tea or coffee for an afternoon treat.
