Peel and chop the apples into cubes.
Add to the slow cooker with the sugar, honey, and cinnamon.
In a bowl, rub the butter in with the topping ingredients (flour, oats, almonds, and sugar), then add that on top of the apples.
Pop the lid on the slow cooker and cook for 3 hours and 15 minutes on high.
For an extra crispy top, place the slow cooker pot if ovenproof without the lid, under the grill for 5 minutes.
