1)First step, eggs

1. Place the mixing bowl on the stand mixer and attach the whisk attachment. Make sure the bowl is clean and dry. Crack the eggs for the brownie into the bowl and add the granulated sugar. Begin mixing at a low speed for about 30 seconds to break up the eggs. Gradually increase the speed to medium high. This will take about 6 minutes, or until they become white-ish.

2)Second step, chocolate and brown butter

1. While the eggs are in the stand mixer you can begin browning the butter. In a light colored sauce pan, melt the butter over medium heat, after a couple minutes it will start to foam, make sure to stir until the butter turns golden brown and develops a nutty aroma. It will take about 5 minutes.
2. In a clean and dry bowl, add the chocolate chips and then pour the browned butter on top to melt the chocolate.

3)Third step, dry ingredients

1. In a clean and dry bowl pour the dry ingredients: all purpose flour, cocoa powder and brown sugar. Mix until they are well incorporated and then pour it to the butter and chocolate mixture. Combine the ingredients together using a spatula.

4)Forth step, eggs into the mixture.

1. To begin take one third of the eggs and gently incorporate them into the chocolate mixture. Use a whisk or mixing spoon to blend them until the texture is well combined.
2. Add the remaining eggs to the bowl. This time use a spatula to fold them into the chocolate mixture. Be gentle during this process you want to combine the ingredients without over mixing as this can affect the texture of the final product. Mix only until you have no more streaks of egg stop as soon as everything is well blended.

5)Fifth step, brownie

1. now take your batter and pour it into a greased cake pan. Make sure to spread it evenly across the pan and set aside. Pre heat your oven at 160 C ( 320 F ).

6)Sixth step, cream cheese

1. Making the cheesecake should take less than 10 minutes. Start by placing the cream cheese in the bowl of a stand mixer fitted with a paddle attachment. Beat the room temperature cream cheese on medium speed until it becomes soft and creamy for about 3 minutes.
2. Once the cream cheese is ready crack the eggs and pour them into the cream cheese and mix until well incorporated.

7)Seventh step, rest of ingredients

1. in a small bowl combine the cornstarch with a few tablespoons of heavy cream and stir until smooth and there are no lumps. This help to prevent the cornstarch from clumping.
2. To the cream cheese add the condensed milk, cornstarch mixture, heavy cream and granulated sugar. Scrape the sides of the bowl to ensure even mixing. Mix until all the ingredients are well incorporated.

8)Eight step, bake

1. Pour the cheesecake batter on top of the brownie batter carefully and bake at 160 C ( 320 F ) for about 1h or until you can see that the edges are set and the center slightly jiggles. Turn off the oven and leave the cheesecake inside for an additional hour with the door slightly ajar. This will help achieve no cracks on the center of your cheesecake. Leave on the fridge for at least 4 h, decorate and serve.
