    1. Preheat oven to 350°F. Line a 9-inch square pan with parchment paper so there are handles hanging over the sides for easy removal. If you’re using a round pan, cut a round circle of parchment paper to line the bottom.
    2. Rhubarb filling: Put all the filling ingredients into a small saucepan. Stir and bring to a boil. It may seem like you need more water, but the rhubarb already has plenty of liquid in it. Turn the heat down to simmer for 5 minutes. Then remove from heat and set aside.
    3. Streusel topping: Combine all the streusel ingredients in a small bowl. Stir until crumbly and set aside.
