So yummy in my tummy, so yummy, so yummy

This I found last night and tried it out. It is probably the best dessert I have made in a long long time.

Crumble:
1 cup flour
3/4 cup old-fashioned oats
1 cup brown sugar, packed
1 tsp cinnamon
1/4 tsp allspice
1/2 cup melted butter or margarine

Fruit:
2 cups diced rhubarb

• Make sure you soak the Rhubarb in cold water for 30 minutes first and remove the outer coating to negate the stringiness
  

2 cups sliced apples

Thick n Gooey Centre:
3/4 cup white sugar
3/4 cup water
2 Tbsp cornstarch
1 tsp vanilla

Mix together flour, oats, brown sugar, spices, and melted butter.
Press half of the mixture into the bottom of a 9" square baking pan.
Arrange the rhubarb and apples evenly on top.

Cook the white sugar, water, cornstarch and vanilla until thick - This should be done slowly over about 30-45minutes while you slowly raise the heat. I would not recommend going much over medium in your heat.

Pour over the rhubarb and apples trying to evenly and completely coat them

Sprinkle the remaining oatmeal mixture on top.

Bake at 350 degrees for 45mins - 1 hour.

Serve warm with ice cream or whipped cream.
