To a food processor, add the almond flour and powdered erythritol. Blend until the dry mixture resembles a fine powder. If you don’t have a food processor, you can whisk these 2 ingredients together in a bowl.
Step 2
Add the egg, vanilla, and almond extract to the food processor. Blend until a rough dough comes together. Make sure that no almond flour is left at the bottom of the food processor.
Step 3
Transfer the dough to a bowl. Knead for a couple of minutes until a smooth dough forms. If the dough is sticky, add a little more almond flour. If it’s too dry, add a tsp or 2 of water.
Step 4
Cut a large piece of cling film and lay it flat on your work surface. Shape the dough into a log and place it on the plastic. Wrap the cling film around the dough, secure it from both sides, and roll it until it becomes a smooth cylinder.
Step 5
Place the marzipan log in the freezer for 20 minutes to firm up. When ready to serve, place it on a serving platter, and cut it into 15 slices. Serve on its own or with melted chocolate.
