Key Lime Cupcake Recipe

The perfect cupcakes for teaming up with a summer BBQ!

Ingredients you’ll need –

70ml buttermilk
225g self raising flour

150g salted butter

225g caster sugar
3 large eggs
1 – 2 limes for juice and zest

Frosting –
60g cream cheese

200g icing sugar

100g unsalted butter

The cupcakes –
In your mixer, weigh out the butter and caster sugar. Make sure the butter has been softened but not melted. Mix this for 3-4 minutes until light in colour. Add in the buttermilk and mix until just combined.



Next, add in 1 egg and 1 spoon of flour alternating until all combined. Squeeze in your lime juice and grate in the zest. Mix by hand.

Pop your batter into some cupcake cases. Ideally fill around 2/3 full. This should do around 12 cupcakes. Put the tray into a preheated oven at 170 for 22 minutes.



While these are cooking, cut up some quarter slices of lime and pop these into a bowl with a sprinkling of sugar and mix.




Into your mixer, put your softened butter in a mixer and on high for 5 minutes. Add in the icing sugar and mix for 5 minutes. Finally add in your cream cheese and mix for 30-40 seconds. All done and delicious!


Decorating –

Pop the frosting into a piping bag. We just snipped the end off. Once the cupcakes are cool, pipe 3 circles each time getting smaller. Finish off with a quarter slice or a sprinkling of lime zest.

Hints and Tips –

If the buttercream seems a little soft for piping, firm up in the fridge for 15 minutes or add in an extra 25g of icing sugar.

You can tell if the cupcakes are cooked when they feel dry on top. If they feel sticky they aren’t done and cook for a further 2 minutes.

The cream cheese frosting is so delicious, it really does go with lots of flavour cupcakes. Try squeezing a little lime juice over the frosting before eating. Yummy!
