Preheat the oven to 350º.

Generously spray a mini muffin tin with cooking spray or grease with butter. Set aside.

In a heatproof bowl, add the chocolate chips and the butter. Set the bowl over a small saucepan of barely simmering water--not boiling!

Melt the chocolate chips and butter slowly, stirring frequently until the mixture is completely melted and smooth.

Remove the chocolate mixture from the heat and whisk in the cocoa powder until smooth. Set aside.

In a separate bowl, whisk together the eggs, sugar, vanilla, and salt until well combined.

Add a couple of spoonfuls of the warm chocolate mixture to the egg and sugar mixture and whisk to temper the eggs.

Pour the remaining chocolate into the egg mixture and whisk until well combined.

Add the all purpose flour and stir with a wooden spoon or rubber spatula until just mixed.

Scoop the brownie batter into the greased muffin tin a tablespoon at a time (or use a #60 scoop).

Bake at 350º for 11-13 minutes until the centers have risen and cracked and a toothpick inserted comes out with very wet and fudgy crumbs--the toothpick should NOT come out clean.

Remove the pan from the oven and allow the chocolate Brownie Bites to sit and cool completely. About an hour.

To remove the bites from the pan, make sure the brownies are completely cool and set. Gently twist the bites out of the pan or use the tip of a sharp knife to gently loosen. Be careful not to scratch up the pan!

Serve and enjoy!
