Remove from the oven and let the dump cake cool on the counter for at least 10–15 minutes. This helps it thicken up just enough while still staying warm and gooey.
Serve warm, scooping the cake straight from the baking dish with a large spoon. Top with ice cream or whipped cream if you like, and enjoy that celebration-worthy smell filling your kitchen.
For picky eaters who aren’t sure about cherries, you can mix half cherry pie filling and half canned apple pie filling to gently mellow the flavor. If your family loves extra chocolate, use a fudge or devil’s food cake mix and double the chocolate chips. For a slightly less rich version, use only 6 tablespoons of butter and add 2–3 tablespoons of milk drizzled over any dry spots before baking. You can also sprinkle chopped pecans or walnuts over the top along with the chocolate chips for a bit of crunch. If you need to make it dairy-free, swap the butter for a dairy-free margarine and skip the chocolate chips or use dairy-free ones. This recipe reheats well—just cover the dish and warm individual portions in the microwave for 20–30 seconds to bring back that gooey, fresh-from-the-oven feel.
