Mix together almond flour and powdered sugar in a medium sized mixing bowl. If using storebought marzipan, grate the marzipan into a bowl along with 100g of powdered sugar.
Add your egg whites and almond extract (omit the extract if using marzipan) to your almond flour and sugar mixture and work together until you have a dough that resembles sugar cookie dough. Add the egg white one tablespoon at a time! The final result may be a little bit sticky, which is totally fine!
Cover the dough and let it rest overnight in the fridge. This is an important step to prevent the dough from spreading when you bake it; if you need to make it the same day make sure it rests for at least a few hours!
The next day, take the dough out of the fridge.
Begin to roll your dough into logs. You are aiming for logs that are about 1cm to 1.5cm in diameter.
To create a pointed top, flatten the edge closest to you by pressing your palm gently on the rolled out log.
Prepare two sheets of parchment paper that you will bake the rings on. If using our design, print out the stencil, making sure you are printing the PDF at 100% size. Place the stencil underneath one of the pieces of parchment paper and use the outline on the stencil to shape the interior edge of the ring (the inside edge of the dough should line up with the outline on the stencil). Make sure the pointed edge you created is pointing upwards! Repeat the shaping process for all ring sizes, moving the stencil to a different area on the parchment paper for each ring. We place five large rings on one sheet, then the remaining rings and the ball on the other sheet of parchment paper. You can also use the stencil to get the general size, then transfer to your prepared baking sheet by lifting the ring onto it. If not using the stencil, roll logs and cut into the following lengths and then shape into rings: 36cm, 33cm, 30cm, 27cm, 24cm, 21cm, 18cm, 15cm, 12cm, 9cm.
Make sure you have enough dough to make a little ball for the top! You should have 10 rings and a ball at the end.
Now is the time to make sure the shape is as even as possible. If you need to, pinch the sides together to get a more triangular shape. The most important thing is that each ring has an even height across it so you can stack another ring on top without any issue of leaning during final assembly.
Preheat your oven to 390 F (200 C).
Place your rings on two baking sheets (either transfer the parchment paper you used which already has the rings on it to the baking sheet, or you may proceed if the rings are already on the parchment paper lined baking sheet); Leave the rings to dry out at room temperature for about 20 minutes.
Before baking, run water along the inside edge of the rings to prevent any wrinkling along the inside edge.
Bake for about 10 minutes until lightly golden. Remember, the larger rings may take a little bit longer, while the smaller ones may take less time. If you want, you can bake these one at a time in the oven to ensure even browning.
Let the rings cool completely at room temperature before icing.
Combine powdered sugar and water (or pasteurized egg white) in a bowl to create a thick icing consistency (we don't use exact amounts for this, we just go by eye!). Use a piping bag or a ziploc bag to ice your rings in a zig zag pattern; let the icing completely set before assembly.
To assemble, melt a little bit of chocolate (we don't have an exact amount, as we just melt as we go. You can also skip this step, it just may be a little less stable!) Brush chocolate along the bottom of the kransekage rings as you are stacking. This will act as the "glue" for the kransekage!
Stack your rings in size order and your tower is complete!
