Remove from the oven and use a butter knife to release the cake from the sides of the tin but do not remove the cake from the tin. Let cake cool completely in the tin.
Once cool, remove the cake from the tin. If cakes have risen unevenly, use a large knife to trim the tops of the cakes so that you have two identical pieces.
Using your large knife, cut each cake section in half lengthwise. If you want to make an 8-sectioned cake like the one in the picture above, cut each piece of cake lengthwise a second time so that you have a total of 8 strips of cake, 4 strips of each color.
Remove marzipan from fridge and roll out between two sheets of wax paper to an 8"x12" rectangle, roughly 1/8" thick.
Heat up your jam with a little bit of water so that its a little runny and then pass it through a strainer to remove any big chunks of fruit. If you don't have a strainer or don't want to remove the chunks of fruit, you don't need to. Totally up to you.
Brush one long side of one piece of cake with jam and place it jam side down on the marzipan so that its lined up along one of the short sides of the marzipan.
Brush the other three sides of the piece of cake with jam. Brush a strip of yellow cake and place jam side down next to the pink strip. Brush the remaining sides of the pink piece of cake with jam.
Repeat two more times along the bottom for a total of 4 strips of cake along the bottom and then construct the second tier, making sure to brush all sides of each strip of cake with jam.
Wrap the marzipan over the top of the cake, leaving the ends of the cake exposed. Trim excess marzipan off of the edges and slice ends to neaten.
Top of the cake can be left plain or a pattern can be incorporated. Store cake in an airtight container.
