The first thing I want you to do is to preheat your oven to 350°F (175°C), allowing it to warm up to the perfect baking temperature.
Carefully arrange the drained peaches in a smooth, even layer at the bottom of your dish, creating a perfect foundation for the rest of the ingredients.
Evenly sprinkle the cake mix over the peaches, remember to not stir, just on the top.
If you'd like, you can drizzle a little of the reserved syrup over the peaches for an extra touch of sweetness!
Place small pats of butter evenly across the top of the cake mix or simply drizzle the melted butter over the whole surface for a smooth, even coating.
If you'd like, sprinkle in a little cinnamon or nutmeg for an extra flavor!
Pop it in the oven for 35 minutes, or until the top turns a golden brown and the peach filling starts to bubble up.
Take it out of the oven and let it rest for 10 minutes to cool slightly before serving.
Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream, and here you go, quick and delicious treat!
