1Preheat your oven to 180°C (350°F).
Core and slice the apples thinly, then arrange them in a baking dish.
In a bowl, mix the rolled oats with cinnamon.
Sprinkle the oat mixture evenly over the sliced apples.
Melt the unsalted butter and drizzle it over the oat and apple layers.
Bake in the preheated oven for 30 minutes or until the apples are soft and the oats are golden brown.
While the apple crisp is baking, carefully break the candy glass into small, bite-sized pieces.
Once the apple crisp is done, remove it from the oven and immediately sprinkle the candy glass pieces on top, allowing them to slightly melt into the warm crisp.
Let the Candy Glass Apple Crisp cool for a few minutes before serving.
