Ingredients

Apple Filling

4 Granny Smith apples (peeled, cored, and sliced)
4 Honeycrisp apples (peeled, cored, and sliced)
¼ cup granulated sugar
¼ cup packed light brown sugar
2 tablespoons freshly squeezed lemon juice (about 1 large lemon)
2 tablespoons cornstarch
1 teaspoon ground cinnamon
¼ teaspoon ground nutmeg

Crumble Topping

1 cup all-purpose flour
½ cup granulated sugar
½ cup packed light brown sugar
½ cup (1 stick) cold salted butter (cut into small cubes)
½ teaspoon ground cinnamon
¼ teaspoon ground nutmeg

Instructions

Peel, core, and slice the Granny Smith apples and honey crisp apples. I peel the skin off and then I use an apple corer, slicer, and cutter that creates 8 slices of apple per apple.
Add the apple slices and all the other apple filling ingredients into your slow cooker. Mix together well until all the apples are thoroughly coated.
4 Granny Smith apples, 4 Honeycrisp apples, ¼ cup granulated sugar, ¼ cup packed light brown sugar, 2 tablespoons freshly squeezed lemon juice, 2 tablespoons cornstarch, 1 teaspoon ground cinnamon, ¼ teaspoon ground nutmeg
In a medium bowl, add all the crumble topping ingredients. Use your clean fingers or a pastry cutter, to pinch and press the mixture together until it forms pea-sized crumbs.
1 cup all-purpose flour, ½ cup granulated sugar, ½ cup packed light brown sugar, ½ cup (1 stick) cold salted butter, ½ teaspoon ground cinnamon, ¼ teaspoon ground nutmeg
Sprinkle the crumble topping evenly over top the apples in the slow cooker.
Place a double layer of paper towels over the top of the slow cooker and then cover with the slow cooker lid.
Cook on LOW heat for 4-5 hours. The apples should be tender and soft, and the crumble topping will be golden brown and cake-like.
Serve warm from the slow cooker with a scoop of vanilla bean ice cream on top. Enjoy!

Notes

Slice The Apples Evenly : This helps them cook at the same rate so they're all soft once the cook time is done. I highly recommend using an apple corer, slicer, and corer to do this. I have linked the one I use in the recipe card.
Don't Slice The Apples Too Thin : The apples will turn into mush if they are sliced too thin. Because the cook time is long (4 to 5 hours) you want to make sure the apples are in thicker slices to hold up to the longer cook time, but not too thick that won't soften in the cook time. Which again, is why I recommend using an apple corer and slicer because it cuts each apple into 8 even-sized slices that are the perfect thickness.
Serve Warm : Apple crumble is at its best when served warm fresh from the slow cooker. I highly suggest serving the crumble with a scoop of vanilla ice cream on top! My family loves vanilla bean ice cream. The cold ice cream just melts right into the warm apple crumble and it's literally the best dessert ever.
Use Fresh Lemon Juice : A little lemon juice balances the sweetness and helps keep the apple flavor bright. Freshly squeezed lemon juice is best for its bright flavor.
Best Served Fresh : This dessert is best served fresh and warm from the slow cooker. Leftovers will reheat well, but for the best texture of the crumble and apples, I definitely recommend eating it fresh and warm after it is done cooking. The crumble does do well on the warm setting, so if needed, you can turn it to warm for a couple of hours while you're serving guests.
Cover With Paper Towels : This helps trap all the condensation before it drips back into the slow cooker and on top of the crumb - it will help prevent the crumble from becoming soggy. Use a double later of paper towels under the lid, or you can use a clean tea towel/kitchen towel if preferred. If the paper towels are becoming soaked during the cook time, quickly change them out with dry paper towels.
