hot fudge pudding cake

This is officially my favorite food. The national food of Stephanieland.

6 tbsp butter
2/3 cup cocoa powder
2 oz bittersweet or semisweet chocolate, chopped (= 1/2 cup chocolate chips)
1/3 cup packed brown sugar
1 cup granulated sugar
3/4 cup flour
2 tsp baking powder
1/3 cup milk
1 tbsp vanilla
1/4 tsp salt
1 egg yolk
1 1/2 cups coffee, at room temperature (*I have used water instead and that works fine too)

Heat the oven to 325 and spray an 8x8" baking dish with Pam.

Melt the butter, 1/3 cup of the cocoa, and the chocolate together in the microwave, stirring often, until smooth (1 to 3 minutes).

In a separate bowl, stir the brown sugar, 1/3 cup of the granulated sugar, and remaining 1/3 cup of the cocoa together. In another bowl, whisk the flour and baking powder together.

Mix the remaining 2/3 cup of the granulated sugar, milk, vanilla and salt in a large bowl. Whisk in the yolk, then the melted chocolate mixture until combined. Whisk in the flour mixture till just combined.

Spread the batter in the baking dish. Sprinkle the brown sugar mixture evenly over the batter. Pour the coffee gently over the brown sugar mixture. Whatever you do, don't stir it! Bake 45 minutes. It's best, if you can stand to wait, to let it cool about 20 minutes before spooning it into bowls. You absolutely must serve it with a ton of vanilla ice cream.
