Chocolate Malteaser Cake

Every week I try to bake a cake. This week I made a Chocolate Malteaser Cake. I got the recipe from Nigella Lawson's Feast but I didn't follow it exactly. I actually didn't have malteasers so I didn't decorate the top and the recipe called for horlicks but i didn't have any so I used Ovaltine instead. Hubby said that it really did taste like a big malteaser :D
