Peel and cut fruit. Toss with 1 tablespoon almond flour and dot with 1 tablespoon of the butter.
In a food processor, combine oats, pecans, remaining 3 tablespoons almond flour, salt, muscovado sugar, granulated sugar, remaining 3 tablespoons melted butter and vanilla. Process until crumbs form.
Sprinkle topping over fruit and bake for 20 minutes, or until crispy and golden brown on top (note: I usually bake the apple crisp a bit longer to get the apples to soften more).
Serve warm. You can also serve with vanilla ice cream for those that can have dairy.
