Bake the pastelitos at 400F for 15-20 minutes, on the highest rack in your oven. If the bottoms are getting dark but the tops are still not golden, you can broil them for a minute or two, but watch them! They can burn in an instant.
Once they're out of the oven, lightly drizzle the pastelitos de carne with the agave nectar, or simple syrup. You don't want to drown them, you just want them to have a kiss of sweetness. Then devour, and repeat!
