Directions
Lightly grease the inside of a 4- to 6-quart slow cooker with butter or nonstick spray so the cobbler doesn’t stick.
Pour the frozen strawberries straight from the bag into the bottom of the slow cooker. Spread them into an even layer; it’s fine if you see ice crystals and frosty berries.
Sprinkle the granulated sugar evenly over the frozen strawberries. Do not stir; just let the sugar sit on top so it can melt down into the fruit as it cooks.
In a medium bowl, stir together the all-purpose flour and the melted butter with a fork until you have a thick, crumbly dough that holds together when pressed. It will be a bit shaggy and rustic, like an old-fashioned biscuit dough.
Crumble this flour–butter mixture evenly over the sugared strawberries, breaking it into small clumps and bits so it covers most of the surface. It does not need to be perfect or completely covered; gaps will let the berry juices bubble up.
Cover the slow cooker with the lid. Cook on HIGH for 2 1/2 to 3 hours, or on LOW for 4 to 5 hours, until the strawberries are bubbling and tender and the topping is set and cooked through in the center. The topping will be soft and spoonable, not crisp like an oven-baked cobbler.
Once done, turn off the slow cooker and let the cobbler sit, covered, for about 15 to 20 minutes. This resting time helps the juices thicken a bit and makes it easier to spoon out neat servings.
Serve the cobbler warm, spooned into bowls with plenty of the strawberry syrup and topping in each portion. Add ice cream or whipped cream if you like, and enjoy the simple, vintage flavor.
Variations & Tips
If your strawberries are very tart, you can add an extra 1/4 cup of sugar over the berries, or stir 1 teaspoon of vanilla extract into the melted butter before mixing it with the flour for a more old-fashioned, bakery-style aroma.
For a hint of Midwestern potluck flavor, sprinkle 1/2 teaspoon ground cinnamon or nutmeg over the sugared berries before adding the topping. If you prefer a slightly more cake-like topping, stir 1 teaspoon baking powder and a pinch of salt into the flour before adding the melted butter; this will give the dough a bit more lift.
You can also swap half the strawberries for another frozen berry, such as blueberries or raspberries, but keep the total amount to about 32 ounces so the cobbler cooks properly. For a less sweet dessert, reduce the sugar to 1/2 cup and serve with sweetened whipped cream.
Food safety tips: Always start with commercially frozen fruit that has been kept at a safe freezer temperature (0°F or below). Do not leave the cobbler sitting on WARM or at room temperature for more than 2 hours; cool leftovers promptly, transfer to a covered container, and refrigerate. Reheat individual portions gently in the microwave until steaming hot before eating. Avoid refreezing leftovers that have already been thawed and cooked, as the texture will suffer and quality declines.
