Preheat oven to 350 degrees and line an 8 x 8 inch pan with a parchment paper.
In a small saucepan over low heat (or in a microwave), melt the fat, sugar, and cocoa powder together, stirring vigorously until a glossy, gritty mixture is formed.
Mixture should be warm, but not scalding hot. Stir in the vanilla and sea salt.
Stir in the flour. Now stir in the eggs, or the egg alternative.
Pour the batter into the prepared pan and spread evenly.
Bake for 25-30 minutes until a toothpick inserted in the center comes out clean.
Let cool completely before attempting to cut. The magic happens in the cooling, I promise!
