Step 1: Prepare the Apple Filling

1. Peel, core, and thinly slice 5 medium apples (about 6 cups). Place in a large mixing bowl.

2. Add 3 tbsp packed light brown sugar, 1 tbsp granulated sugar, and 2 tsp apple pie spice. Toss until the apples are evenly coated.

   • Tip: Slice apples thinly (about ¼-inch thick) for even cooking. Use a mix of tart (Granny Smith) and sweet (Honeycrisp) apples for balanced flavor. Toss thoroughly to ensure spices coat all slices.

Step 2: Prepare the Crumble Topping

1. In a medium mixing bowl, stir together 1 ¼ cups all-purpose flour, ¾ cup packed light brown sugar, ¾ cup quick oats, and ½ tsp apple pie spice until combined.

2. Pour in ½ cup melted salted sweet cream butter and stir until the mixture forms moist, crumbly clumps.

   • Tip: Use a fork to mix the crumble for even texture. Ensure butter is fully melted for easy incorporation. If too dry, add 1 tbsp more melted butter; if too wet, add 1 tbsp flour.

Step 3: Layer in the Slow Cooker

1. Lightly grease a 4-6 quart slow cooker insert with cooking spray or a thin layer of butter to prevent sticking.

2. Spread the apple filling evenly across the bottom of the slow cooker.

3. Sprinkle the crumble topping evenly over the apples, covering the filling completely. Do not stir; the layers will meld during cooking.

   • Tip: Use a slow cooker liner for easy cleanup. Spread apples in an even layer to ensure consistent cooking. Pat the crumble gently to adhere but keep it loose for texture.

Step 4: Slow Cook

1. Cover and cook on low for 3-4 hours or high for 2-3 hours, until the apples are tender and the topping is set but still slightly soft (it will crisp slightly as it cools).

2. Check doneness at the minimum time; if the apples aren’t soft, continue cooking for 30-minute increments. If the topping looks too wet, remove the lid for the last 30 minutes to evaporate excess moisture.

   • Tip: Place a paper towel or clean dish towel under the lid to catch condensation and prevent a soggy topping. Avoid lifting the lid too often to maintain heat. Cooking times vary by slow cooker model.

Step 5: Cool and Prepare Optional Toppings

1. Turn off the slow cooker and let the apple crisp rest for 5-10 minutes to cool slightly, making it easier to scoop and allowing the flavors to settle.

2. If using, ensure vanilla ice cream and caramel sundae topping are ready. Warm the caramel topping slightly (10-15 seconds in the microwave) for easier drizzling.

   • Tip: Let the crisp cool slightly to avoid melting ice cream too quickly. Store caramel topping at room temperature for easy pouring.

Step 6: Assemble and Serve

1. Scoop the warm apple crisp into 8-10 bowls or dessert cups (about ½ cup per serving), ensuring each portion has a mix of tender apples and buttery crumble.

2. Top each serving with a small scoop of vanilla ice cream (about ¼ cup) and drizzle with 1-2 tsp caramel sundae topping for indulgence.

3. Serve warm for a cozy, campfire-inspired experience. Pair with coffee, hot cider, or a dessert liqueur (like Baileys) for a festive vibe.

   • Tip: Serve in wide bowls to showcase the golden crumble and melting ice cream. Drizzle caramel in a zigzag for a polished look. Offer extra caramel or chopped nuts on the side for customization.
