Preheat your oven to 400°F (200°C). Gather all ingredients.

In a medium saucepan, combine peaches, light brown sugar, cornstarch, vanilla extract, ground cinnamon, and sea salt. Cook over medium heat until bubbling, then simmer for 10-15 minutes.

In a mixing bowl, combine butter, granulated sugar, all-purpose flour, ground cinnamon, and sea salt. Mix until it resembles coarse crumbs.

Distribute the warm peach filling between two ramekins, then sprinkle the topping evenly over each.

Bake on a cookie sheet for 15-20 minutes until bubbly and golden brown.

Let cool for 5 minutes before serving.
