Can you make this cobbler in a regular oven?
Yes. Spread the berry mixture in a greased 9×13 baking dish, sprinkle the dry cake mix and butter over top, and bake at 350°F for 45–50 minutes until golden and bubbling.
Do you need to thaw the frozen berries first?
No. Add them directly from the freezer to the slow cooker—the cornstarch and lemon juice will draw out liquid and thicken the filling as it cooks.
How long does it take to cook on low vs. high?
Cook on low for 6–8 hours or on high for 3–4 hours until the berry filling is bubbling at the edges and the cake topping is set and golden.
Can you substitute the cake mix?
Yes. Use yellow or vanilla cake mix, or make a homemade topping with flour, sugar, butter, and baking powder mixed into a crumble.
Is this recipe gluten-free?
