1/2 cup milk chocolate chips
1/2 cup semi-sweet chocolate chips
1 stick unsalted butter, cut into cubes
2/3 cups granulated sugar
1/3 cup cocoa powder (plus additional for dusting pan)
1 teaspoon salt
1 teaspoon vanilla extract
4 large eggs
Preheat the oven to 350ºF.
Grease a 9-inch springform pan with butter or cooking spray. Line the bottom of the pan with parchment and grease the paper.
Fill a pot with about 2-inches of water and bring to a slow boil. Place a glass bowl over the pot and add the butter and chocolate. Let that melt while stirring occasionally until smooth. Next remove mixture from the heat. Add the sugar, cocoa powder, vanilla and salt and whisk until well incorporated. Add the eggs, one at a time, whisking until incorporated.
Pour into springform pan, place on a baking sheet and bake for 30 minutes until the top has formed a little crust. Remove from the oven and let cool.
Finally remove from pan and enjoy with fruit, whipped cream or ice cream.
