• Preheat your oven to 350 degrees Fahrenheit and prepare a 9-inch by 9-inch baking dish (or equivalent size) by greasing it with butter. Place it on a baking sheet and set aside.

For the peach filling:

• In a large bowl combine the peaches, lemon juice, sugar, cornstarch, cinnamon and nutmeg. Toss everything together gently.
• Pour the filling into the prepared dish and smooth out the top.

For the crumble topping:

• In a separate bowl, combine the flour, sugar and cinnamon for the crumble topping with a fork or a whisk.
• Add the cubes of cold butter and use your hands to mix them into the flour mixture until the mixture resembles very coarse crumbs (kind of like wet sand).
• Sprinkle the topping mixture over the filling in an even layer.
• Place the baking sheet with the filled baking dish in the oven and bake at 350 degrees for about 35-45 minutes or until the topping is golden brown and the filling is bubbly. You may have to turn the dish in your oven once during baking for even browning.
• Remove from the oven and let cool for about 10-15 minutes before serving with a scoop of vanilla ice cream.
