2 cups brown sugar
2 cups all-purpose flour
6 tablespoons unsweetened cocoa powder
4 teaspoons baking powder
1 teaspoon salt
1 cup milk
4 tablespoons butter, melted
1 teaspoon vanilla extract
1-1/2 cups brown sugar
1/2 cup unsweetened cocoa powder
3 cups boiling water
1. For the cake: Mix together the sugar, flour, cocoa, baking powder, and salt in a large bowl. Stir in milk, melted butter and vanilla until combined. Spread the batter over the bottom of a large crock pot.
2. For the fudge topping: Mix together the brown sugar and cocoa. Sprinkle mixture over the cake batter.
3. Pour the boiling water over the top. Do not stir! Cover and cook on high for 2 to 2-1/2 hours.
4. Turn off heat, and remove lid. Let sit 20-30 minutes before serving, so its still warm but won't burn your mouth.
