Preheat the oven to 350º Fahrenheit. Prepare a nonstick mini muffin pan with cooking spray (or use paper liners).
In a large bowl, whisk together the sugar, butter, vanilla, and eggs until combined.
Stir in the flour, cocoa powder, and salt until just combined.
Using a cookie scoop, distribute the dough evenly among the cupcakes.
Bake for 13 minutes or until an inserted toothpick comes out clean. Try not to over bake these. You want them to stay chewy!
Once they have cooled, pop them out of the tin and top with dulce de leche using a small star tip and icing bag.
Sprinkle with sea salt.
