🛒 Ingredients
The Berry Base:
- 24 to 32 oz (approx. 2 bags): Frozen mixed berries (strawberries, blueberries, raspberries, and blackberries)
- 1/4 cup: Granulated white sugar (adjust based on how sweet your berries are)
- 2 tbsp: Cornstarch (crucial for thickening up the delicious fruit juices)
- 1 tbsp: Lemon juice
The Cobbler Crust:
- 1 box (15.25 oz): Yellow cake mix or White cake mix
- 1/2 cup (1 stick): Unsalted butter, melted
- 1/2 tsp: Ground cinnamon
The Icing Drizzle & Topping:
- 1/2 cup: Powdered sugar
- 1 to 2 tsp: Milk or heavy cream
- For Garnish: A handful of fresh, raw mixed berries to pile high in the center
👩🍳 Step-by-Step Instructions
- Prep the Slow Cooker: Lightly coat the inside of your slow cooker insert with non-stick cooking spray or a thin rub of butter.
- Mix the Berry Filling: Dump the frozen mixed berries directly into the bottom of the slow cooker. Add the granulated sugar, cornstarch, and lemon juice. Toss everything gently with a spoon until the berries are evenly coated and spread them flat across the bottom.
- Prepare the Topping: In a medium mixing bowl, combine the dry yellow cake mix and ground cinnamon. Pour in the melted stick of butter. Stir with a fork until the mixture forms a coarse, crumbly, gravel-like texture.
- Layer the Crumble: Scatter the buttery cake mix crumbles evenly across the entire surface of the berry layer. Do not pack it down tightly; keep it loose so heat can circulate.
- The Paper Towel Trick (Crucial step!): Place a large, clean paper towel across the top of the slow cooker opening, then place the heavy glass lid firmly over it. Why? The paper towel absorbs the rising steam, preventing condensation from dripping back onto your crust, ensuring it bakes up beautifully crumbly instead of soggy!
- Slow Cook: Cook on HIGH for 2.5 to 3 hours (or Low for 4 to 5 hours). You will know it’s ready when the berry juices are bubbling furiously around the edges and the cake mix topping is fully set and a light golden brown.
- Glaze & Garnish: In a tiny bowl, whisk the powdered sugar and milk together until a thick, smooth glaze forms. Drizzle the icing in patterns all over the warm cobbler crust. Pile your extra fresh berries right into the center for a gorgeous presentation.
- Serve Warm: Scoop it out warm straight from the pot and always serve it alongside a massive scoop of vanilla bean ice cream!
