Fresh blackberries work beautifully when they’re in season.

White cake mix or vanilla cake mix also works if that’s what you have in the pantry.
 

3. Butter

You’ll need one cup of melted butter, which is two sticks.
 
This is the ingredient that turns dry cake mix into a rich, golden topping whenever you make a blackberry dump cake.
 
Don’t swap it for oil or margarine if you can help it, because real butter gives the best flavor and texture.
 

4. Optional Add-Ins

A little sugar, cinnamon, or lemon zest sprinkled over the berries adds extra depth when you make a blackberry dump cake.
