Heat up a non-stick frying pan, toast the black sesame seeds for around 5 minutes on low to medium heat or until aromatic. Taking care not to burn the sesame seeds.
Transfer the black sesame seeds to a Nutribullet or food processor, blend the sesame seeds until you get a fine paste.
Transfer the ground sesame seeds to the non-stick frying pan, add desiccated coconut, extra virgin olive oil and agave sugar, stir well to form a smooth and thick paste on low to medium heat. Transfer to a bowl and cool in the refrigerator.
Once cooled, divide and roll the sesame paste into 22 small balls (about 2cm/0.8 inch in diameter) and set aside on a large plate. You may have some extra sesame paste leftover.
For the dough:
Add all the glutinous rice flour in a large bowl, make a well in the middle and add 1 cup of water, agave syrup, vanilla extract and salt, use a spatula to mix briefly.
Then start kneading with your hands and gradually add the rest of the ½ cup water as you knead into a smooth and slightly sticky dough.
Pinch and shape the dough into around 22 equal size balls (around 45g/1.6oz), flatten the balls into a 3 inch disc with your fingers with the middle thicker than the edges and fill each disc with 1 small ball of the black sesame paste.
Wrap the black sesame ball with the dough and fold into half. Pinch some dough from the sides to fill the top of the dough and gently form a smooth ball with your palms and place on a large plate. Repeat with the rest of the dough until finished.
Dip each ball into a bowl filled with some water and immediately coat each ball generously with some white sesame seeds, roll and shape into a rounded ball again while pressing the white sesame seeds onto the balls.
For cooking the filled sesame balls:
Heat up a wok filled with some rice bran oil to 120C or 250F and just enough to cover the sesame balls.
Turn the heat to the lowest setting and carefully drop about 7 balls into the wok and cook for about 5 minutes or until lightly golden brown on low heat. Drain on kitchen paper towel. Repeat and cook the balls in 3 batches.
