Preheat the oven to 350°F and prepare a 9x13 pan with a light coating of cooking spray.
Spread 42 ounces canned strawberry pie filling evenly across the bottom of the prepared pan.
Carefully distribute 1 box vanilla cake mix over the strawberries in an even layer.
Pour 1 cup butter over the cake mix.
Bake in the preheated oven for 50-55 minutes, or until the top is golden brown.
Remove from the oven and allow to cool for 10 minutes before serving.
Notes
Strawberry dump cake can be stored at room temperature on the first day, then covered in the fridge for up to 4 days.
We love to serve this warm with a scoop of vanilla ice cream or a mound of whipped cream. Make it look extra fancy by adding a sprig of fresh mint!
We like to use a spoon or a small measuring cup to help control the sprinkling of the cake mix over the pie filling.
Don't forget to give the pan a gentle shake once you've added the cake mix. This helps get the mix into all the nooks and crannies and helps prevent dry cake bites!
This recipe was made for canned pie filling, but homemade will work well, too!
