Oil repels water. Oil is hydrophobic. The fat molecules inside cocoa powder are hydrophobic too. They repel water. On the other hand, the starch molecules are hydrophilic. They love water. Milk is mostly water, so the same rules are true for milk. When you dunk the cocoa powder in milk, the starch molecules quickly absorb the milk. At the same time, the fat molecules stop the milk from getting any further than the surface. This creates a shell of milk around the outside of the cocoa powder. When you poke it with a toothpick, you break the shell’s surface tension. The milk rolls off the cocoa powder, and back down into the cup.
