In a bowl, combine all the dough ingredients except for the flour. Gradually add flour until you achieve a soft and smooth dough. Refrigerate for 30 minutes.
Combine the nuts, almonds, and cinnamon.
Preheat the oven to 355°F (180°C).
Divide the dough into four parts and roll each part on floured parchment paper. Evenly spread the date spread, sprinkle the nut mixture, and roll into a log using the baking paper. Repeat this process for the remaining dough portions.
Place the rolled dough with the parchment paper on a baking sheet. Using a sharp knife, make deep triangular cuts, and then bake for about 30 minutes or until golden brown.
Allow the cookies to cool on the countertop for 10 minutes and then sprinkle with powdered sugar.
