In a medium skillet (cast iron works best), toast the sesame seeds over low heat until fragrant. Once cool, place in a blender with a pinch of salt and blend until smooth. Add sugar to taste and blend to incorporate.
For the oats
Add black sesame butter and a few tablespoons of the milk to a jar. Stir until well mixed. Add remainder of the milk and other ingredients, seal the jar, and shake vigorously. Refrigerate overnight.
Portion into 2 bowls and top with coconut, poppy seeds, sliced banana, and a drizzle more sesame butter.
