Recipe: Rhubarb-Berry Crisp

Who needs another crisp recipe? You do!

Rhubarb Berry Crisp | I'll Make It Myself! 4

This recipe combines rhubarb, raspberries,  and blackberries with my family’s oatmeal topping and a hint of ginger. It’s a snap to throw together and perfect for cuddling up with some Twin Peaks and coffee on those spooky proto-autumn PNW summer nights when the temperature drops and it actually rains.* I’ve made this with a combination of rhubarb, raspberries, and blackberries, as well as with double the blackberries and no raspberries. It’s great either way, and would be good with rhubarb and raspberries only, too.

This recipe is dairy-free and vegan if you use a butter substitute. I’ve made it with Earth Balance and it turned out perfectly. If you’re using frozen berries or rhubarb, you may want to cook it for an additional 5-10 minutes or so to cook off some of the juices.
