1. В В Adjust oven rack to middle position and preheat oven to 350°F.
Grease and flour eight six-ounce ramekins and arrange on a rimmed baking sheet. 2. В В Whisk flour, cacao powder, baking powder, baking soda, and salt together in a bowl.
In another large bowl, whisk coconut milk, palm sugar, oil, eggs, and vanilla together. Slowly whisk flour mixture into coconut milk mixture until combined. 3. В В Press batter into prepared ramekins, dividing equally. (Batter will be thick, like cookie dough.) Gently press a piece of cacao into the center of each ramekin to submerge.
Bake until cakes rise and the tops turn glossy (about 20 minutes, rotating sheet halfway through baking); the center should be gooey when pierced with a skewer.
Do not overbake.
Serve warm.
