The secret that makes a dump cake truly wonderful is that all you have to do is dump all the ingredients into the pan. Begin by spraying the pan with nonstick cooking spray and getting your oven preheated so that it's ready to go.

Next, dump the blueberry pie filling into the pan and spread it out. Add the fresh blueberries on top of the pie filling. Drop dollops of lemon pie filling all over the top of the blueberries and then spread it out as much as possible to create the lemon layer.

Spread the dry yellow cake mix evenly all the way to the edges of the pan covering the entire surface of the pie filling. Melt the butter and pour it over the top, trying to cover every inch of the cake mix for best results. Bake your dump cake for forty-five minutes and then serve it hot with ice cream.

Tips for Best Results

Try to get the melted butter spread out evenly all over the cake mix so that every part will be transformed by the butter as it bakes.

Our fresh blueberry lemon dump cake works best with in-season blueberries and is a great summer dessert.

Substitute lemon curd or prepared lemon pudding for the pie filling if needed.

If you use small spoonfuls of lemon pie filling all over the surface and then spread it out, it will be easier to spread than if you dump it all in the center and spread from there.

Substitute a lemon cake mix for the yellow cake mix if you want an added intensity for the lemon flavor. Vanilla cake mix will also work. Try to go with a regular cake mix and not one of the fancy "supreme" mixes.

Blueberry lemon dump cake is just one possibility! Change it up and use strawberry pie filling and sliced strawberries in place of the blueberry for an equally delicious strawberry lemon dump cake. You could even try raspberries and raspberry pie filling. All of these are classic flavor combinations with lemon.
