Decadent Chocolate Sauce

Combine cocoa powder and butter in a small saucepan over medium heat, stirring constantly until the butter melts and the mixture becomes smooth, about 2 minutes.

Pour the sweetened condensed milk into the saucepan while continuing to stir, blending it thoroughly with the cocoa and butter until no lumps remain.

Heat the sauce gently, stirring frequently, until it reaches a consistent, glossy consistency and begins to steam slightly, about 5 minutes total.

Remove the saucepan from heat and stir in the vanilla extract until fully incorporated.

Pour the chocolate sauce into a serving dish or drizzle directly over desired desserts while warm, as it will thicken slightly as it cools.
