Add to a large bowl, flour, sugar, cocoa, baking powder, baking soda, and salt. Whisk to mix well.
In a small bowl, combine the milk, oil, and vanilla.
Make a well in the center of the flour mixture. Pour the milk mixture into the well.
Mix until well combined.
Topping
In a small bowl, combine the brown sugar and cocoa. Mix well.
Assemble
Prepare your large crockpot. Either apply grease to the entire interior or use a liner.
Pour the cake mixture into the crockpot.
Sprinkle the topping over the top, dispensing it evenly.
Pour the hot water over the top of the cake. DO NOT STIR IT IN!
Cover the crock pot. Set to low and cook for 3 hours. Check with a toothpick in the cake for doneness. It should come out of the cake clean. NOTE: The bottom will be a pudding-like mixture.
If the cake is not done, allow to continue cooking on low setting until the toothpick tests out clean.
Serve warm and enjoy!
Notes
Note:
This pairs nicely with vegan ice cream or vegan whipped topping.For those raspberry enthusiasts, consider adding a spoonful of raspberry topping when serving.
