Rock cakes are simply the easiest British baked good to make. They are also known as rock buns, depending on where you live in the United Kingdom. The recipe, however, is always the same: A simple dough made of flour, baking powder, butter, sugar, milk, and egg is studded with dried fruit, rolled into balls, and baked.

Children love to make them, and may also have a fondness for them since they happen to be one of Harry Potter's favorite tea time treats.

Recipe Variations

  • You can also add a teaspoon of mixed spice. If you can't find mixed spice, try using pumpkin pie spice.
