The filling
To prepare the strawberry rhubarb filling, we will need six cups of fruit total. I like to balance the tartness of the rhubarb out with an equal amount of strawberries, so I suggest 3 cups of chopped rhubarb and 3 cups of sliced strawberries.
To prepare the rhubarb, make sure to discard the leaves first, as they are poisonous and should not be consumed. Wash the stalks well, then slice each stalk in half lengthwise before chopping into 1/2 inch pieces. You do not want any larger than 1/2 inch as they may not cook through.
Strawberries should have their stems removed and cut into 3-4 slices each.
The fruit is tossed in granulated sugar and 1/4 cup flour. As the crisp cooks, the flour helps the juices of the fruit thicken into a delicious, velvety sauce.
The oatmeal cookie crisp
Traditional fruit crisp recipes have a simple crisp made from butter, sugar, flour and oatmeal. For this recipe, we are putting a fun twist on this by using oatmeal cookies in addition to these ingredients. This gives the crisp topping a crunchier and slightly nutty flavor.
To prepare the crisp, you will first process the cookies in a food processor until chunky. You could also place them in a ziplock bag and hit it with a wooden spoon.
Next, we will mix with melted butter, oatmeal, flour, sugar and a touch of cinnamon. Sprinkle on top of the strawberry rhubarb filling.
