This Dump Cake is an easy, gooey chocolate dessert recipe with a built-in fudge sauce.

A simple batter is made with flour, cocoa powder, and other pantry staples, then topped with brown sugar, more cocoa, and hot water—creating a rich pudding-like layer as it bakes.
Once you layer the ingredients, don’t mix — this is what creates the rich fudge sauce underneath.

Chocolate chips and pecans add texture, and after 40 minutes in the oven, it’s ready to be topped with ice cream, whipped cream, and cherries.
You’ll know the cake is done when top has a brownie-like crust while the bottom remains soft and pudding-like.
Customize the Toppings! Try caramel sauce, crushed cookies, or peanut butter drizzle for extra flavor.


Serve your cake warm for the ultimate indulgent treat! Keep in an airtight container in the fridge for up to 3 days. Reheat before serving.
