I'm not familiar with the grape nuts recipe you refer to and Judy's recipes are always so good but I thought I would pass this along also. It's a favorite of my husband's. Bakes similar to a custard pie, not the kind of creamy rice pudding I grew up with.

Rice Pudding (Custard)

3 slightly beaten eggs
2 cups milk
1-1/2 cups cooked rice *see note*
3/4 cup granulated sugar
1 teaspoon vanilla
1/2 cup raisins (optional)
1/2 teaspoon salt
cinnamon (topping)

Preheat oven to 325 degrees. Spray Pam in a 10 x 6 x 2" glass oven dish. Mix all ingredients except cinnamon. Pour into prepared dish and bake for 25 minutes. Stir well. Sprinkle cinnamon generously over the top. Continue baking an additional 25 minutes or until knife comes out clean from center.

*Note: My husband loves the custard part so I reduce the rice to between 3/4 c. to 1 cup so there is a fair amount of custard. He is not that fond of raisins so I have never added them. I use leftover converted rice - have never tried minute rice.
