Step 1

Preheat the oven to 350°F and line an 8x8 pan with foil and lightly grease. Set aside.

Step 2

In a medium sized bowl over low heat, melt the butter. Add in the sweetened condensed milk and stir with a whisk. Add in the dark chopped chocolate and continue mixing until everything is smooth and melted. Remove from heat and set aside.

Step 3

In a large bowl, beat the eggs, egg yolk, vanilla, and both sugars. Whisk vigorously for 2 minutes until light and airy. There should be bubbles forming. You may also use an electric mixer for this part to save elbow grease!

Step 4

Add in the chocolate mixture from earlier and gently fold together using a spatula. Do not overmix!

Step 5

Add in the flour and unsweetened cocoa powder and continue mixing until no streaks appear.

Step 6

Toss in the chocolate chips and mix for a few seconds.

Step 7

Pour into a prepared 8x8 square pan and spread out evenly. Bake for 22-25 minutes or until a toothpick inserted comes out slightly fudgy. If it is wet with batter, continue baking. Turn off oven.

Step 8

Slightly open the oven door for 10 minutes and allow the hot air to come out. Then completely remove the brownies from the oven and cool on the counter.

Step 9

While the brownies are cooling, melt all of the ingredients together on low heat or in the microwave at 15 second intervals. Make sure to stir in between!

Step 10

Drizzle over cooled brownies. Allow to set and enjoy!
