These cookie cups are like double height cookies that open to reveal a gooey Mars centre when you bite in.

Mars bar fans will go wild for these Mars cookies. They are baked inside cupcake cases, so they're a bit like a hybrid of a cookie and a cupcake. You add half the dough to the bottom and top it with a generous chunk of Mars. Then you cover the chocolate bar over with more cookie dough. These are best eaten still slightly warm from the oven, when the filling will still be melty and hot. Just be careful it's not too hot, though. You can even serve them up as a pudding, with a squirt of cream or a ball of ice cream filling the dip in the top of the cookies.
