Pre-heat the oven to 160C Fan/350F/Gas Mark 4 and grease and line a 2lb loaf tin
Mix together the butter and caster sugar using an electric mixer or a spoon until light and fluffy, around 3 minutes
Add the eggs and milk and whisk in until well incorporated
Before you whisk in the flour, take away a spoonful and mix it into the blueberries to fully coat them with flour. Then whisk the remaining flour into the cake mixture gently until fully combined
Fold in the lemon zest
Put a layer of the cake batter, about 1cm deep into the base of the lined tin
Then gently fold the blueberries into the remaining cake batter
Pour the batter into the loaf tin and bake for 1 hour, or until a skewer inserted in the centre comes out clean. Leave to cool fully
Mix the lemon juice with icing sugar until you get a pourable consistency, drizzle it all over the cake
Add some blueberries and lemon zest to decorate if you like
Store in an airtight container in a cool place and eat within 3 days

Notes
Make sure all your ingredients (particularly the butter and eggs) are at room temperature before you start baking.
I used a baking spread for the cake, but you can use unsalted butter too.
You will need a 2lb loaf tin for this recipe (you can test the size of your loaf tin by seeing how much water the tin can hold, 2lb will hold about 2 pints/1100ml of water). If you have a 1lb loaf tin, simply halve the ingredient amounts.
Although I provide cup measurements, I highly recommend weighing your ingredients out using digital kitchen scales. It is the most accurate way to measure ingredients and will ensure the best results. Digital scales are very low cost and can be purchased for around £12 ($16.50) .
For teaspoon (tsp) and tablespoon (tbsp) measurements, please use measuring spoons and not the type of spoons you eat with. Again this will ensure accuracy and provide the best results.
