This never fails to please; walnut and maple syrup sponge cakes, which are frosted and sandwiched together with maple fudge frosting/icing, divine! This is NOT a light airy-fairy sponge cake, as it is made with soft brown sugar to enhance the fudge and maple flavours - and it needs to be fairly robust to hold the walnuts in the cake mixture. It is however, a soft pudding type cake with lots of texture and an amazing taste. Of course this can be made with excellent maple syrup from the USA, but I have called it a Canadian cake, as the maple syrup and maple extract was sent to me by a kind Zaar friend in Canada. The cake is baked in two cake tins; the two cakes can then be cut in two again, making a three-layer cake, (four pieces of cake = three layers) it depends on how high they rise. If you do make a three-layer cake, you may need a little more fudge frosting and filling. This cake keeps very well in an airtight container or tin for up to a week. The cake can also be frozen before icing and frosting – defrost it overnight, then assemble and ice the cake when fully defrosted. Pecans can also be used in place of walnuts – but I prefer the taste of walnuts with the maple syrup.
