Easy blackberry cobbler
This blackberry cobbler is quick to prepare and always popular. It uses a lemon cake mix for a bright, balanced sweetness that pairs beautifully with tart blackberries. Fresh berries are ideal when in season, but frozen work fine if fresh ones aren’t available.
The cake has a tender, moist texture with bubbling fruit beneath a golden topping. Serve warm with vanilla ice cream or whipped cream for a classic finish. The oats in the topping add a pleasant crunch and a homemade feel without extra fuss.

Dump cakes are a great no-fuss dessert: canned or fresh fruit, a boxed cake mix, oats or other topping ingredients, and butter are combined and baked. They store well in the refrigerator for a few days and reheat nicely.
What is a dump cake?
A dump cake is assembled in a single dish by layering the components rather than mixing a batter from scratch. For this blackberry cobbler you’ll layer the berry mixture, oats, cake mix, and butter so the fruit becomes a jammy base while the top bakes to a crisp, cake-like crust.
Some variations use canned fruit and different cake or brownie mixes. You can easily swap berries—try raspberries, blueberries, or cherries—or add chopped nuts for texture. Using frozen berries is convenient; just thaw and drain any excess liquid before assembling.
Popular dump cake variations
Pineapple dump cake is a classic and often features brown sugar and butter for a rich topping. Raspberry and blueberry versions are also common, and you can adapt the topping with self-rising flour or oats and a touch of almond extract for extra depth. Whipped cream or ice cream makes a delightful alternative to the traditional brown sugar topping.
