Preheat oven to 350°. Line cookie sheets with parchment paper.
Sift together the flour, cinnamon, cardamom, baking powder and salt. Stir in pecans and set aside.
In separate bowl beat together sugars and butter.Add eggs & vanilla and beat until creamy.
Roll dough into 1" balls and place on cookie sheet. Flatten each ball to about ¼" thick. **I use a 1½ tsp measuring spoon (or ½ Tbsp).
Bake for 11-12 minutes until edges are starting to brown. Remove to rack until completely cooled.
Melt chocolate in microwave in 30 second increments, stirring each time until melted.
Sandwich each cookie together with 1-2 teaspoons of chocolate. Drizzle or spread chocolate on top of each cookie. Top with chopped with pecans or toffee bits as desired.*You can chill in refrigerator for up to an hour to speed setting up of chocolate. Allow to return to room temperature.
