Chocolate muffins - a classic

I have to admit that these are not my favourite muffins, but it was the only recipe for which I had all the ingredients at home :-)
They're still nice and so easy to make, and there are probably very few people in the world who don't like chocolate muffins!

Choco muffins

255 g plain flour
2 tsp baking powder
1/2 tsp bicarbonate of soda
1/2 tsp salt
150 g white granulated sugar
4 tbsp cocoa powder (unsweetened)
1 egg
250 ml milk
1 tsp vanilla essence
90 ml sunflower oil

Sift in a bowl the flower, baking powder, bicarbonate of soda, sugar and cocoa poder.
In another bowl, beat egg and add milk, vanilla and oil.
Pour the wet mix into the flour mix. Stir all together just until combined (it shouldn't be overstirred!).
Fill 12 muffin cups. Bake in the oven for 23 minutes at 185C. I use the fan oven for baking muffins, if you have the top and bottom oven you'll need to increase the temperature 10-15C.
