For the fruit filling, throw rhubarb, strawberries, ¾ Cup granulated sugar and orange zest into a large bowl.
In a separate bowl, mix the cornstarch into the orange juice until it’s dissolved. Pour into bowl with fruit and mix well. I used fresh squeezed orange juice just because we fresh oranges. I used a lemon juicer, which worked just fine, as long as you don’t mind a little orange juice in your eye.
Pour fruit mixture into a 8-by-11-inch baking dish. Place this on a baking sheet lined with parchment paper (to catch mixture if it bubbles over). Don’t pay any attention to the pan in the photo, it’s the wrong size. It has a higher lip, so I didn’t need to worry about it bubbling over.
For the topping, use an electric mixer with a paddle attachment and combine the flour, ½ cup sugar, brown sugar, salt and oatmeal. With the mixer on low speed, add the cold butter and mix it until it’s moist and starts to “crumble.”
Sprinkle the topping over the fruit, covering it completely.
Bake for one hour, until fruit is bubbling and topping is golden brown.
Serve warm with ice cream. Enjoy!
