Tammy, I'm surprised nobody's posted this old chestnut yet. It isn't a flake ceral, but it usually is called Homemade Grape-nuts.(posted 9674 days ago)4c wholewheat flour 1c dark syrup
1 teaspoon salt
1 teaspoon baking soda
4 tablespoons sugar
Moisten with buttermilk or sour milk until it is thick and stirable. Bake like a cake. When cool, crumble and dry in oven. Run through a food chopper.
There are other versions of this recipe out there, this is from a Mennonite cookbook. I'll watch for one that has better cooking instructions. Somewhere I came across a person who reported making a recipe like this. The person felt that it was too much work and too much energy (baking and drying) for what you get.
As for a flaked cereal, possible you could bake this after pouring the batter into crepe-like sheets, and then hand-crumble it. Gerbil
