Preheat oven to 425 degrees. Using a double boiler, begin to melt 1 1/4 cups butter.
Add 1 1/2 cups chocolate chips. Use dark, milk, or whatever kind you prefer.
Combine the butter and chocolate chips.
Once butter and chocolate have melted, remove from heat and add 1/2 cup flour and 1 1/2 cups powdered sugar. Combine.
Add 3 eggs and 3 egg yolks, 1/2 teaspoon sea salt, and 1 teaspoon vanilla extract.
Beat ingredients together.
Pour mixture into a baking dish or muffin tin. Bake for 10 minutes.
When cake is done baking, cut around the inside edge of the dish and carefully flip upside down, releasing the cake onto a plate.
Garnish with ice cream, raspberries, shaved chocolate, and powdered cocoa.
