Brownie Bottom Cheesecake

So my sister came to visit a couple of months ago and brought a book called "Blissful Brownies". She was excited for us to make a recipe for the site that she found in the book. So out came the pots, pans, mixers, and good ol' quality time. Enjoy the results of an enjoyable Saturday afternoon. Cooking is always better when you have good company. 

The ingredients:

Brownie Base:
4 oz unsalted butter
4 oz bittersweet chocolate broken into pieces

1 cup sugar
2 eggs beaten
1/4 cup milk
1 cup all purpose flour

Topping:
2 1/4 cups cream cheese
2/3 cup sugar
3 eggs beaten
1 tsp vanilla extract
1/2 cup plain yogurt
melted semisweet chocolate to drizzle (optional)

 Hardware:

1 large bowl
1 blender
1 sauce pan
3 measuring cups (1 cup, 1/2 cup, & 1/4 cup)
Brownie pan (not pictured, not sure how I forgot that)

Directions:

1. First things first. Melt the butter and chocolate pieces your sauce pan over low heat stirring frequently. The stirring frequently is VERY important.
2. After about 10-15 min you will have a nice smooth mixture.
3. Next pour your mixture in your bowl with your sugar (1 cup) and beat it together.
4. After it has been beaten stir in your flour until blended. You will notice that it will thicken up quite well.  
5. When you have took a moment to admire your work so far pour your brownie mix in your brownie pan. Bake the brownie for 25 min on 350. If you want keep some of the unused batter to drizzle on top at the end.
6. Remove from oven and let cool. Lower the oven temp. to 325 Congrats!! You just successfully made a brownie from scratch. *Pat on the back*
7. While the brownie is cooling its time to make the top part. Beat together the cheese, sugar, eggs, and vanilla extract until well blended. Then stir in the yogurt.
8. Pour the topping on your brownie evenly.
9. Once you have your topping bake further for 45-55 minutes in the oven for 325. Bake until the center is almost set.
10. When it is done in the oven remove and run a knife along the edge to loosen from the pan. Allow to cool before removing from the pan. Chill in the fridge for at least 4 hours. Overnight is fine also.
11. Drizzle with some chocolate or some of the brownie batter. Voila! you have made a fantastic looking dessert.
