Step 1: Preheat your oven to 350°F (175°C). Lightly grease a 9x13 inch baking dish.
Step 2: Pour both cans of strawberry pie filling into the prepared baking dish and spread evenly.
Step 3: Drop small spoonfuls or dollops of the softened cream cheese over the strawberry pie filling. Try to distribute them somewhat evenly across the dish.
Step 4: Evenly sprinkle the dry cake mix over the strawberry and cream cheese layers. Make sure the entire surface is covered.
Step 5: Slowly pour the melted butter over the dry cake mix. Try to cover as much of the cake mix as possible with the butter. If using, sprinkle the optional chopped nuts over the butter.
Step 6: Bake for 45-50 minutes, or until the topping is golden brown and bubbly around the edges. A toothpick inserted into the cake topping should come out clean (avoiding the gooey bottom layer).
Step 7: Remove from oven and let cool for at least 15-20 minutes before serving. This allows the filling to set slightly. Serve warm, perhaps with a scoop of vanilla ice cream or whipped cream.
