Ingredients

Scale

Filling

  • 8 Granny Smith green apples, peeled, cored, and sliced (about 2 pounds)
  • 1 teaspoon vanilla extract
  • 1 tablespoon fresh lemon juice (about ½ a lemon)
  • 1½ teaspoons cinnamon
  • ½ cup brown sugar or sweetener (see notes)

Crumble Topping

  • 1 cup rolled oats
  • ½ cup all-purpose flour
  • ½ cup brown sugar or sweetener
  • ½ teaspoon cinnamon
  • 3 tablespoons melted butter (measured solid, then melted)

Additional

  • Clean kitchen towel or several layers of paper towels (to absorb moisture)

Instructions

  1. Prepare the apples: Add the peeled, cored, and sliced apples to the slow cooker. A 7-quart slow cooker works well for this recipe.
  2. Mix the filling spices and liquids: In a bowl, combine vanilla extract, fresh lemon juice, brown sugar or sweetener, and cinnamon. Sprinkle this mixture evenly over the apples and gently stir to coat all the apple slices.
  3. Make the crumble topping: In a separate bowl, mix rolled oats, flour, brown sugar or sweetener, cinnamon, and melted butter. If the mixture feels too dry, add additional melted butter or a little water to achieve a crumbly but moist texture.
  4. Layer the topping: Spread the crumble topping evenly over the apple filling in the slow cooker.
  5. Prevent condensation drip: Place a clean kitchen towel or several layers of paper towels under the slow cooker lid. This step absorbs excess moisture and prevents condensation from dripping onto the topping, which could make it soggy. Then place the lid on the slow cooker.
  6. Cook the apple crisp: Cook on High for 2 to 3 hours or on Low for 4 to 5 hours. The apples should become tender but not mushy, and the filling should bubble around the edges.
  7. Check for doneness: Test the apples by inserting a fork or knife; they should pierce easily with little resistance. The crumble topping should be golden and slightly crisp to the touch.
  8. Cool and serve: Allow the apple crisp to cool slightly before serving to let the topping set and flavors meld.

Notes

  • Brown sugar can be substituted with natural sweeteners like coconut sugar or a sugar substitute for lower sugar options.
  • Peeling the apples is optional but helps create a smoother texture in the filling.
  • Using a towel under the lid is key to keeping the topping crisp in the slow cooker environment.
  • Serve warm, optionally with vanilla ice cream or whipped cream for a classic pairing.
