1. Prepare Slow Cooker and Make Batter Topping:
- Grease the insert of your 5-quart (or 6-quart) slow cooker.
- Make Batter: In a medium mixing bowl, whisk together 1 cup of the all-purpose flour, 2 tablespoons granulated sugar, 1 teaspoon baking powder, ¼ teaspoon ground cinnamon, and ⅛ teaspoon salt until well combined.
- In a separate small bowl, whisk together the room temperature large egg, the warmed ¼ cup of 2% milk, and the 2 tablespoons of slightly cooled melted butter until smooth.
- Pour the wet ingredients into the bowl containing the dry ingredients. Stir with a fork or rubber spatula just until the mixture is moistened and combined. The batter will be thick; be careful not to overmix it.
- Spread this thick batter evenly onto the bottom of the greased slow cooker insert.
2. Prepare and Layer Peach Filling:
- Peel, pit, and slice your fresh peaches into roughly ½-inch thick slices. You should aim for about 6 cups of prepared fruit.
- In a separate large mixing bowl, gently combine the sliced peaches, the remaining ¼ cup of all-purpose flour, the 2 tablespoons of packed brown sugar, 1 tablespoon of fresh lemon juice, and 1 tablespoon of vanilla extract.
- Toss the peaches carefully until they are evenly coated with the sugar and flour mixture.
- Spoon this prepared peach filling mixture evenly over the batter layer already in the slow cooker.
3. Slow Cook the Cobbler:
- Cover the slow cooker securely with its lid.
- Cook on the HIGH setting for 1 hour and 45 minutes to 2 hours (1 ¾ – 2 hours).
- The peach cobbler is done when the peach mixture is bubbly and visibly simmering around the edges, and the batter topping underneath is cooked through and has a cake-like texture. A toothpick inserted into the center of the topping portion should come out mostly clean or with just a few moist crumbs attached.
4. Serve Warm:
- Turn off the slow cooker. It’s a good idea to let the cobbler sit for a few minutes (about 10-15) with the lid off; this allows it to cool slightly and for the delicious peach juices to thicken up a bit more.
- Serve the Slow-Cooker Peach Cobbler warm, scooped directly from the slow cooker into individual bowls.
- It is especially delicious and highly recommended to serve it with a generous scoop of vanilla ice cream, if desired. The contrast of the warm cobbler and cold, creamy ice cream is divine! Enjoy this comforting treat
