My husband paid the highest compliment. He's been looking for a crisp that reminds him of when he was a kid, and this was the closest he has come. He loved it, and for me, that's the best. I will be making this for years to come, and rhubarb is easy to grown and comes back year after year. Warm with ice cream is amazing. Bob's all purpose gluten free flour was my main ingredient
1Pre heat over to 350. Mix oatmeal, flour, brown and coconut sugar, cinnamon. Add melted butter and mix until crumbly. In a greased 8 x 8 or 9 x 9 pan, add 3/4 of mix and press into the bottom of the pan.
2Add 1 inch rhubarb, fresh or frozen.
3In a saucepan, combine sugar (I used pure cane sugar) water and corn starch. Cook over medium heat until bubbly and thickened. Remove from heat and add vanilla. Pour over rhubarb and add crumb topping. Bake 1 hour. Cool, enjoy
