Wash the apples. On a cutting board, remove the core and peel skin of the apples. Cut the apples into cubes.
In a bowl, mix apples with sugar with a spoon. After, add flour and cinnamon, and mix again.
Separate the apple mixture evenly in 4 Mason jars and press with a spoon to compact it.
In a bowl, add the crumble ingredients and mix into crumbs.
Place the jars on a baking sheet. Preheat oven at 190 C degrees or 375 F degrees and bake in the oven for 15 minutes or until the crumble is golden brown at the top and you can see the bubbles through the sides of the jars.
Cool the mini apple crisp in a jar for about 10 minutes and serve warm.
