If your Tres Leches cake isn't absorbing the milk mixture properly, it could be due to a few reasons: Cake Density: If the cake is too dense or not aerated enough, it might not absorb the milk well. Ensure you beat the eggs and sugar properly to incorporate air and make the batter light. Not Enough Holes: You need to pierce the cake thoroughly with a fork or a skewer after baking. More holes mean more spaces for the milk to seep in. Overbaking: Overbaking can dry out the cake, making it less absorbent. It’s crucial to bake just until a toothpick comes out clean. Cooling Time: If the cake is too hot when you pour the milk, it might not absorb well. Let it cool to room temperature first.
