Apple Rhubarb Crisp
I love apple crisp, and I love rhubarb crisp, so I tried combining different amounts of apple and rhubarb and came up with this recipe that everyone loves. Best served warm.
apples, cored and diced
6
large
diced rhubarb
1
cup
white sugar (Optional)
1
cup
all-purpose flour, divided
1 ¾
cups
ground cinnamon, divided (Optional)
1 ½
teaspoons
quick-cooking oats
1 ¾
cups
brown sugar
1
cup
chilled butter, cut into pieces
1
cup
white sugar, or to taste (Optional)
2
tablespoons
 Gather the ingredients. Preheat the oven to 350 degrees F (175 degrees C). Butter a 9x13-inch baking dish.
  Mix apples, rhubarb, 1 cup white sugar, 1/4 cup flour, and 1 teaspoon cinnamon in a bowl until thoroughly combined. Spread fruit mixture into the bottom of the prepared baking dish.
  Mix oats, remaining 1 ½ cups flour, and brown sugar in a separate bowl; cut in butter until crumbly. Spread evenly over fruit mixture.
  Mix 2 tablespoons white sugar with remaining 1/2 teaspoon cinnamon in a small bowl; sprinkle over oat topping.
  Bake in the preheated oven until fruit is bubbling and thick and topping is golden brown, about 45 minutes. Let cool 10 to 15 minutes, then serve.
