How to Make It
Preheat your oven to 350°F (175°C).
In a baking dish, layer your mixed berries evenly on the bottom.
Sprinkle the yellow cake mix evenly over the berries.
Drizzle the melted butter over the cake mix.
Pour the lemon-lime soda gently over the top.
Finish with a splash of lemon juice and a pinch of salt.
Bake for 35-40 minutes until bubbly and golden brown.
Serve
Serve warm with a scoop of vanilla ice cream or just on its own. The juices will be pooling, and the middle will stay soft, making it perfect for spooning right from the dish. Enjoy!
