Pre heat the oven at 180 degree c and line a cup cake tray with cupcake liners.
In a mixing bowl, cream butter and sugar till it becomes pale and frothy.
Then, one by one add the eggs while whisking with an electric hand mixer or whatever apparatus you have.
The eggs should be fully incorporated and then sieve in the flour along with cocoa and baking powder.
Using a spatula, fold the flour in gently with the batter. Add vanilla extract and the drops of liquid food colour. If you are using gel food colour, you need to add too much.
You can expect a pale red kind of colour when folded properly. It becomes a nice red once baked.
Finally using a spoon, drop equal quantities into the cup cake liners and place in the oven to bake for about 30 minutes or until a skewer comes out clean when poked in the centre.
Once th cupcakes are done, place them on a wire rack to cool down completely,
