Sorry, I guess I could post the recipe. Duh. It's nice to have good friends to point out when you're an idiot.
1 cup all-purpose flour
2 teaspoons baking powder
6 tablespoons butter
2 ounces semisweet chocolate (or 1/3 cup chocolate chips)
1 cup sugar (2/3 cup & 1/3 cup, added separately)
3 tablespoons plus 1/3 cup Dutch-processed cocoa
1 tablespoon vanilla extract
1/4 teaspoon salt
1/3 cup milk
1 egg yolk
1/3 cup brown sugar
11/2 cups hot water
Whipped cream or ice cream
Coat the inside of a 2 1/2- to 5-quart slow cooker with cooking spray. (Note: the cake's cooking time and final appearance will vary depending on your crock's size.)
Whisk together the flour and baking powder in a medium bowl and set aside. In a large bowl, melt the butter and chocolate in the microwave or over a pan of simmering water and mix well.
Whisk in the 2/3 cup of sugar, 3 tablespoons of cocoa, vanilla extract, salt, milk, and egg yolk. Add the flour mixture and stir until thoroughly mixed.
Pour the batter into the slow cooker and spread it evenly. In a medium bowl, whisk together the remaining sugar, cocoa, and hot water until the sugar is dissolved.
Pour the mixture over the batter in the slow cooker. Cover and cook on high for 1 to 2 hours, depending on the size of the crock pot.
Even when done, the cake will be very moist and floating on a layer of molten chocolate, but you'll know it's ready when nearly all of the cake is set and the edges begin to pull away from the sides of the pot. (As you check, try not to let the condensed steam from the lid drip onto the cake.)
When it's done, turn off the power and remove the lid. Let it cool for 25 minutes, then serve it in bowls topped with whipped cream or ice cream. Makes 6 to 8 servings.
I think it would be great with raspberries and whipped cream :)
HERE'S THE MYSTERY. It isn't very clear on when to add the brown sugar, so I added mine when it says "remaining sugar" and dissolved it in the water with the granulated sugar. If you feel the need to add it to the cake batter instead, please let me know how it works out for you. I'm curious. I also used a 6 quart crock pot and it needed at least 1.5 hours, maybe two to be sure. It needs to look very done on the top. Enjoy!
