This is my go-to dessert for parties - a fruit crisp (which is a variation on a fruit cobbler) can be prepared without gluten, sugar, or dairy. It is super flexible, really easy to make, and yummy year round. (Though I prefer to eat hot desserts in wintertime, this is really good with summer fruits that are overly ripe). You can use fresh, frozen, or canned fruit.
Today this fruit crisp took me exactly 5 minutes to throw together, and 40 minutes in the oven. Measurements are approximate - I'm bad like that. Use enough fruit to fill your pan (I used a 9" square glass pan) about 2/3 of the way full. Make enough topping to cover the fruit.
Preheat oven to 350F. No need to grease the pan unless you want to.
2 cups frozen rhubarb
2 cups frozen mixed berries
1/2 cup applesauce
4 TB water
1/4 cup (1/2 stick) butter, room temperature (can substitute as needed with non-dairy shortening of choice: margarine, coconut oil, etc.)
2 cups oatmeal (not instant)
1 cup brown sugar (can use another granular sweetener like stevia if preferrred)
2 TB flour (optional)
1/4 cup chopped nuts (optional)
Dump fruit in pan. Spoon applesauce over the top. Sprinkle with water. You can also sprinkle with sweetener if you would like.
Put ingredients for topping in a bowl and using your hands or a pastry blender, crumble it up, distributing the shortening evenly throughout the oats and sugar.
Spread topping over fruit and bake for 1 hour (or if using canned fruit, until top is brown and insides are bubbling :)
