To prepare the orange truffles desserts recipe, you'll need: 1 cup orange zest, 1 tablespoon orange juice, 2 tablespoons confectioners' sugar, and 1 teaspoon vanilla extract. In a medium mixing bowl, whisk together the flour, baking powder, cinnamon, nutmeg and salt. Pour the dry ingredients into the wet ingredients and stir to combine. Form the mixture into balls and roll them in the sugar mixture. Chill the balls in an airtight container for at least 1 hour before serving.
