How to Make It
In a bowl, thoroughly blend the brown sugar with the oil, Lyle's Golden Syrup and molasses. Beat in the egg. In another bowl, stir the almond meal with the cinnamon, baking soda, cloves, ginger, pepper and cardamom. Stir the dry ingredients into the brown sugar mixture until well blended. Refrigerate the dough for at least 1 hour or overnight.
Preheat the oven to 350° and line 2 baking sheets with Silpats or parchment paper. Scoop the dough into heaping 1-tablespoon mounds and roll into 20 balls, then roll the balls in the demerara sugar. Set the balls 2 inches apart on the prepared baking sheets. Bake the cookies for about 14 minutes, rotating the sheets halfway through baking, until they are slightly firm. Let stand for 5 minutes, then transfer the cookies to a rack to cool completely.
Scoop the ice cream onto the underside of half of the cookies and top with the remaining cookies. Press together slightly and serve.
