Preheat oven to 175C/350F/Gas 4 and place 40 cupcake cases into muffin tins
Combine all the ingredients for the cupcakes in a large bowl and beat with an electric whisk/mixer for about 3-4 minutes until smooth and fluffy
Divide the batter into the cases (I use an ice-cream scoop)
Bake the cupcakes for 20 minutes
Allow to cool for 5 minutes before placing on a wire rack to cool completely
When the cupcakes are cool, use a cupcake corer (or a teaspoon!) to scoop out a small portion of the cake from the centre of each cupcake, fill each hole with a couple of morello/black cherries and pour in a drop of syrup too
To make the buttercream, beat the butter, icing sugar, vanilla and cherry syrup together using an electric whisk/mixer. I added a small amount of cherry syrup to start and adjusted to taste. Beat for 1-2 minutes until smooth and creamy
Fill a large piping bag with the buttercream and pipe swirls on top of each cupcake
Cover with chocolate sprinkles and place a cherry on top
