Step 4: Top with butter
Slice the butter into pats and arrange them evenly over the top of the cake.
Step 5: Bake and serve
Bake the dump cake for 40 minutes; it should be puffed with browned areas that look like crust and others that look gooey and melty. Let the cake cool for at least 10 minutes, and then use a large spoon or spatula to serve. It tastes best when it’s warm.
