preheat the oven to 350˚
line an 8x8 cake pan with foil back parchment OR just foil, make a divider right down the middle of the pan to make 4x8 inch sides, butter or grease the pan completely
If you're using the multi-size cake pan be aware that you must still line this pan with foil to make a divider to make the correct size cakes unless you have an extra divider wall
beat the butter and sugar in a stand mixer with the paddle attachment until soft and fluffy, about 5 minutes, stop halfway through and scrape down the bowl
add the eggs, one by one until the are fully incorporated, scrape down the sides of the bowl between eggs
measure the flour by loosening it up, then spoon into the measuring cup
add the flour and vanilla to the butter mix, and beat until it's smooth
pour half the batter in one half of the prepared pan, smooth out the top
tint the half of the batter light pink and then pour it in the other half of the prepared pan
bake in the hot oven until a toothpick comes out clean, 25-30 minutes
while the cake is baking make the marzipan
mix the almond flour and powdered sugar together in the bowl of the stand mixer with the paddle attachment
add the corn syrup and the vanilla, stir to combine
when the mixture is crumbly pinch it together to see if it holds together, if it doesn't add another 1/2 teaspoon of corn syrup
butter your hand and knead the marzipan on a clean counter to combine
at this point, you could add a drop of food color gel and make it colored marzipan or leave it cream-colored
either way, once you finish it you can roll it in a log, wrap it up in plastic,s and tuck it in the fridge until ready to use
once the cake is done remove it from the oven, let it cool ten minutes then turn it out of the pan and leave to cool on a cooling rack
when ready to assemble remove the marzipan from the fridge and roll it out on a counter dusted with powdered sugar, cut to a rectangle 12x8, if it's too cold to roll or crumbles, let it warm up while you assemble the cake
trim and cut the cakes to make them 1 1/2 inches wide by 8 inches long, trim them as needed
lay two of the opposite color on the bottom, stick them together with apricot jam, layer the other two on top putting jam between the top and bottom layers, and the two sides
then spread the last of the jam over the long edges of the cake
set the cake on the rolled out marzipan, and fold the marzipan up and over the cake matching the cut edges, trim as needed to fit, then turn the whole cake over so the seam is on the bottom
cut a slice off both ends of the cake so it's neat and clean
you can dust it with powdered sugar or score the top in a diagonal pattern
