These inexpensive metal mugs can be found in the camping department and are a great addition to your Sun Oven.
Single Serving Sun Oven Peach Crumble
For the filling:
4 peaches, cut into thin wedges
1/4 cup sugar
1 tablespoon fresh lemon juice
1 teaspoon cornstarch
For the topping
1/4 cup brown sugar, packed
1/4 cup all purpose flour
1 cup muesli (Red Bob Mills is my favorite)
1/4 cup cold butter
Set Sun Oven out to preheat. Spray 4 metal mugs or 4 ramekins with cooking spray; set aside.
In a medium bowl toss the peaches with the sugar, lemon juice, and cornstarch. Divide evenly among the prepared mugs.
In another bowl, whisk together the brown sugar, flour and muesli. Blend in the butter with your fingertips until mixture resembles a coarse meal. Divide the topping evenly over the peaches in the mugs. Arrange the mugs on a rimmed baking sheet and bake until the filling is bubbling and the topping is golden, 45 minutes to 1 hour. Cool on a rack for 10 minutes. Serve with ice cream or whipped cream.
