Purée drained chickpeas in food processor or blender until very smooth. (This may have to be done in batches, depending on the size of the food processor or blender.) Add tahini, brown sugar, Marzipan, and Vanilla Cookie flavours and blend until very smooth and well incorporated.
Place in mixing bowl and stir in the mixed ingredients. Refrigerate for 2 hours or overnight.
Scoop dough into large golf ball-sized balls, place on greased or parchment paper-lined cookie sheet, and flatten with a fork.
Bake at 325°F for 16-20 minutes, rotating halfway through baking time. Cookies will be lightly browned. Let cool and enjoy!
