Hidden away in the comments is not the best place to find a recipe, so here is one that SusanM has shared for some gorgeous-sounding Chocolate Muffins - do let us know if you try them! Thank you very much for the recipe, SusanM.
CHOCOLATE MUFFINS by SusanM
Dry ingreds: 250 g SR flour sifted,
4 tablespoons drinking choc OR 2 tablespoons cocoa powder, 100g choc chips or chopped chocolate, 175g caster sugar. MIX TOGETHER IN A BOWL.
Wet ingreds: 250 ml milk, 90ml veg oil, 1 egg. MIX TOGETHER IN A BOWL OR JUG.
Combine dry and wet ingredients and stir well. Pour into 12 large muffin cases and bake at 180 (165 fan) for 25 minutes. Cool on a wire rack. These freeze well.
For chocolate chips I just use half of a 150g bar of luxury dark cooking chocolate from Aldi at 69p a bar and roughly chop. I also reduce the amount of sugar slightly (pretending to be healthy!) Enjoy x
