Preheat the oven to 400 degrees. Spray 4 ramekins with cooking spray.
In a large bowl combine the strawberries, lemon juice, flour, sugar, and cinnamon. Toss until combined and divide between the ramekins. Set aside.
In another bowl cut the butter into small pieces and place them in the bowl. Add the flour, brown sugar, cinnamon, and salt. Using your hands mix together the butter with the other ingredients until it resembles wet sand.
Sprinkle the crumble over top of the strawberries in the ramekins.
Place the ramekins on a baking sheet and bake for 25 minutes.
Remove from oven and cool for 5 minutes. Top with a mound of whipped cream and enjoy!
