Slow Cooker Caramel Apple Crisp

5 Stars 4 Stars 3 Stars 2 Stars 1 Star

No reviews

Tender spiced apples slow-cooked in a rich caramel sauce of brown sugar, butter, apple cider, and vanilla, topped with a golden buttery oat crumble. The apples braise gently for hours, soaking up the caramel until deeply flavoured and saucy. The oat topping cooks on top, absorbing just enough steam to turn golden and chewy with crisp edges. Served warm with vanilla ice cream or cold double cream. Cosy, deeply satisfying, and almost entirely hands-off.

  • Total Time: 3 hours 15 minutes – 4 hours 15 minutes
  • Yield: 6 – 8 servings 1x

Ingredients

Scale

Caramel Apple Base

  • 6–7 medium apples — peeled, cored, and sliced into ½ inch pieces; Granny Smith, Honeycrisp, Braeburn, or a mix
  • 113g (½ cup) unsalted butter, cut into pieces
  • 150g (¾ cup) dark brown sugar, firmly packed
  • 60ml (¼ cup) apple cider or good-quality apple juice
  • 1 tsp pure vanilla extract
  • 1 tsp ground cinnamon
  • ¼ tsp ground nutmeg
  • ¼ tsp ground cardamom (optional but recommended)
  • Pinch of ground allspice
  • ¼ tsp fine salt
  • 1 tbsp cornstarch mixed with 1 tbsp cold water

Oat Crumble Topping

  • 120g (1¼ cups) old-fashioned rolled oats — not instant or quick oats
  • 75g (½ cup) plain flour
  • 50g (¼ cup) granulated sugar
  • 75g (⅓ cup) dark brown sugar, packed
  • 1 tsp ground cinnamon
  • ¼ tsp ground nutmeg
  • ¼ tsp fine salt
  • 57g (¼ cup) unsalted butter, melted
  • ½ tsp pure vanilla extract
  • Handful of chopped pecans or walnuts (optional)

To Serve

  • 6–8 generous scoops vanilla ice cream, or cold double cream poured freely

Instructions

Step 1 — Prepare the caramel base Add the butter, dark brown sugar, apple cider, vanilla extract, cinnamon, nutmeg, cardamom, allspice, and salt to the slow cooker insert. Stir briefly to combine — it will look unincorporated at this stage. That’s fine. Turn the slow cooker to LOW and let it begin warming while you prepare the apples.

Step 2 — Prepare and add the apples Peel, core, and slice the apples into pieces roughly ½ inch thick — thin enough to cook through, thick enough to hold their shape. Toss the slices with 1 tbsp of lemon juice to keep them bright, then add them to the slow cooker and stir to coat everything in the caramel base. Spread them into an even layer.

Step 3 — Make the oat topping In a medium bowl, combine the rolled oats, flour, granulated sugar, brown sugar, cinnamon, nutmeg, and salt. Pour the melted butter and vanilla extract over the top and stir until everything is evenly moistened and clumping together. Fold in the chopped nuts if using. The mixture should feel like wet sand that holds together when pressed.

Step 4 — Layer and cook Spoon the oat topping evenly over the apples in the slow cooker. Do not stir it in — it needs to sit on top to form a distinct topping layer. Cover and cook on LOW for 3–4 hours, or on HIGH for 1½–2 hours, until the apples are completely tender and the caramel sauce is bubbling thickly around the edges. Avoid lifting the lid during cooking — every peek adds time.

Step 5 — Optional: finish under the grill For a crispier, more textured topping, carefully transfer the oat layer to a baking tray lined with foil, spread it out, and place under a hot grill for 3–5 minutes until golden and crisped. Watch it closely — it goes from golden to burnt quickly. Spoon it back over the apples before serving.

Step 6 — Serve immediately Scoop the warm caramel apple filling generously into bowls, making sure to get plenty of the sauce from the bottom. Add the oat topping, then finish with a large scoop of vanilla ice cream or a generous pour of cold double cream. Serve straight away while the contrast between warm filling and cold cream is at its best.

Notes

  • Apple variety is everything. Use at least two varieties for the best balance of flavour and texture. Granny Smith brings tartness and holds its shape brilliantly under heat. Honeycrisp adds natural sweetness and a softer bite. Braeburn or Pink Lady add complexity. Avoid Red Delicious — they have almost no flavour once cooked and turn to mush.
  • Use old-fashioned rolled oats. Quick oats or instant oats will turn soggy and disappear into the filling rather than forming a distinct topping. Old-fashioned oats hold their texture and give the crumble its characteristic chew.
  • For a crispier topping. The slow cooker environment creates steam, which softens the topping. If you want real crunch, the grill finish in Step 5 is the solution. Alternatively, bake the topping separately in the oven at 180°C / 350°F for 15 minutes and add it at the table.
  • Sauce consistency. If the caramel sauce looks too thin when the cooking time is up, mix an extra teaspoon of cornstarch with a teaspoon of cold water, stir it into the hot filling, replace the lid, and cook for a further 15 minutes. It will thicken as it sits too.
  • Make ahead and storage. The apple filling can be made up to 2 days ahead and stored in the fridge — reheat gently in a saucepan before serving. The oat topping keeps separately in an airtight container for up to 5 days. Fully assembled leftovers keep refrigerated for 3 days and reheat well in the microwave or a low oven.
  • For a dinner party. Start the slow cooker 3–4 hours before you want to serve dessert. The filling will hold on the WARM setting for up to an hour without overcooking, giving you flexibility around timing. Make the oat topping in advance and add it to the slow cooker for the final hour only.
