Add mixture into a 8x8 inch (20x20 cm) baking pan lined with greased parchment paper. Firmly press down mixture until it is one smooth layer. (If you grease the spatula as well it will prevent the mixture from sticking to it!)
Bake 15-20 minutes, or until golden brown. Let cool 10 minutes.
Drizzle top with melted dark chocolate. Chill for 30 minutes, or until dark chocolate is solid.
Cut into 8 equal pieces.
Wrap each bar in parchment paper or foil.
Store in the freezer for up to 3 months or in the refrigerator up to 1 week.
