Adjust the oven rack to the center position and preheat your oven to 350° F.
If using a ceramic pan, lightly grease it with nonstick baking spray and set it aside. If using a glass or non-stick pan, you don't need to grease it.
In a large bowl, add cake mix & the full can of strawberry pie filling. Using a whisk, gently mix with just the tip of the whisk to avoid the powder from getting all over. Once the mixture begins to combine, use the full whisk and beat until fluffy and combined.
Pour mixture into the cake pan, and bake for 35-40 minutes. The top will be fluffy, and cracked, but will slightly sink as it cools.
Allow cake to cool for 15 minutes before slicing & enjoy!
