Reviews for Rhubarb Oat Bars
"These were a delicious way to use up the few stalks of rhubarb left after making a pie. I agree that the base and topping are crumbly, but it was more the top that was crumbly for me. I think the rhubarb filling bled into the base a bit and made it just right for me. However, next time I will add a bit more butter to the top to help it hold together a bit more. Tastes great!"
"Excellent. Used a couple of the suggestions below. After dividing the topping in half, added 1 more TBLS of butter for the bottom to help keep it together and added 1/2 cup of chopped pecans for the topping."
"These bars are amazing. I took Danerlea's suggestion and used TOH Chocolate Caramel Bar crust for the top and bottom (I did not add coconut). Top with ice cream when they are warm and gooey fresh from the oven. Good the next day also (I refrigerated them). If you like this recipe you should try another great TOH recipe--Rhubarb Raspberry Slab Pie."
"I made this twice already! I added 1/4 cup chopped pecans and it's the best crust/topping ever!,"
"I agree with the previous review- this recipe needs a little tweaking. The bars are delicious- but they are impossible to eat without a fork and plate. I think the next time I make them I'm going to double the filling and add coconut to the crust from TOH's Chocolate Caramel Bars."
