Glenn's Rhubarb Crumble

Recipe by  

"I modified this recipe with an extra 1/4 cup white sugar. I also added a modifier so that you can make extra streusel to smash around the bottom and sides to form a crust. The crumble on the top is extremely delicious!"

If you like rhubarb, this is a good one. I made mine in a 7 x 11 size pan instead of a 9 x 13 pan as the recipe only calls for 3 cups of rhubarb. Rhubarb cooks/bakes down a lot and I wanted a thicker dessert. I also used 1 cup of sugar omitting the need for the extra ¼ cup especially since the topping has another cup of sugar in it. The bake time and temp is spot on for this recipe. We enjoyed it warm the first night with vanilla ice cream and room temp the next evening. It was good both ways, but the topping is definitely better on the first night as it crunchier, which is how my family likes it. On the second day the topping absorbed the liquid from bottom layer, although still very good, just not as crunchy. A very good dessert that I will be making again with all the rhubarb I froze this season. Thanks, Glenn for sharing your recipe.

I started writing my take on this recipe and I accidentally hit enter, so I will try again. First time making this and I guess I thought it was going to be like it looks in the picture; a lot of rhubarb in a serving. It turned out to be more like candy. It was thin, dry and awfully sweet. I'm not trying to say it was really bad, cause my friends still ate some, it just wasn't as fruit filled as I thought it was going to be. Maybe it's supposed to be a thin type of dessert.

I really like this recipe. I did not add the egg and instead added extra flour. I also added an extra cup of rhubarb. Perfect!!

I used this recipe as a starter for the basics and then tweaked it..thank you for the base recipe! For those interested I added a full tsp of cinnamon wherever it called for a 1/2...I love cinnamon. I used 1/2 cup of sugar and the rest stevia natural sweetener (18 of the little scoops)... I added 1 cup of apples (gala) and 1 1/2 cups strawberries.. the topping I used just a bit less brown sugar and just under 3/4 cup of butter. There is LOTS of topping!! I just finished tasting it and I'm so happy there is a whole pan left to eat!! its amazing. possibly sweeter due to the stevia and doesn't even need ice cream! mmmmm.. thumbs up!

YUM! But what's not to like with butter and brown sugar! I used about 5 cups of diced rhubarb to cover bottom of 9 x 13 and kept the other ingredients the same. Also used slightly less butter for top - a little over 3/4 cup. Very good and very sweet!
