I am so excited to be adding this Lemon Cupcake Recipe to our collection of Mini-Dessert Recipes. Lemon cake is sometimes tricky to get right, and we have one killer recipe for you today.

An easy and delicious lemon cupcake recipe that hits the perfect sweet-sour balance, topped with a generous scoop of homemade lemon buttercream. The perfect grown-up party cupcake

It’s so easy to overdo it with the sweetness on a lemon cake, trying to overcompensate for the sour punch. What you really want is a gentle balance of sweet-sour that tingles your tastebuds and hits a delicate balance. It should pair perfectly with a coffee, tea, or party punch but you shouldn’t need to take a sip with every bite. Eating mini desserts can be so great! 

Buttermilk is one of my favourite baking ingredients as it can really bring a bit of nuance and it reacts wonderfully with different flavours – in my Red Velvet Cupcake recipe it helps turn the cocoa red, and here it helps carry through the sour note of the lemon while also mellowing it out to be palatable.

A grown-up twist on the traditional party cupcakes, this lemon cupcake recipe is rich and perfectly sweet-sour

To decorate, I wanted a generous “scoop” of thick lemon frosting and so that’s exactly what I did – I used an ice cream scoop and topped each cupcake with frosting before dipping them in multi-coloured sprinkles. I love this effect for a party cupcake, or you can alternatively try a cream cheese frosting or meringue topping. (I’ll be trying those next time.)

Yum! These lemon cupcakes are that perfect sweet-sour combo and super cute to boot!
