bread knife butter knife
First things first: wash your hands. Outrageously important. Once you have done that, cut the tops, bottoms, and edges off the cakes, then cut each cake into equally sized squares with a bread knife. Take one square of each flavor (you should have two) and cut them each in half the long way, so you have the top and bottom half of each square. Then, once you have decided which flavor you want on top, use the butter knife to spread a layer of jam onto your bottom flavor, then place the top flavor on top of the jam. Do that with the rest of the squares.
Now would be a good time to heat up your frosting/glaze to soften it. Put your layered square things on wire cooling racks on top of wax paper and ladle or spoon the frosting/glaze over them, allowing it to drip down the sides.

You can use frosting for the middle layer instead of jam, if you like. Also, you can decorate the tops with icing or something similar. I made a simple swirly design with store-bought edible flavorless black sparkly decorating gel that is easy to use and comes in lots of different colors at target. Sounds too good to be true, right? Anyway, I highly recommend using this product. It's your choice, though!
