I was looking for a way to use up some of my Special K cereal (I'm sure you could use an equivalent cereal - corn flakes, bran flakes, etc.) and found this recipe on the Kellogg site. It's pretty tasty and very easy - and I think you could vary it with different fruit, or by adding some cinnamon or nutmeg.
1 1/2 cups Special K® (crushed to 3/4 cup)
1/4 cup sugar
2 tablespoons margarine, melted
1 cup Special K®
1 3/4 cups all-purpose flour
1/3 cup sugar
4 teaspoons baking powder
1/2 teaspoon salt
1/4 cup margarine, softened
2/3 cup skim milk
1 can (16 oz.) peach slices in light syrup, drained and chopped
2. Crush the 1 cup cereal to fine crumbs. In mixing bowl combine cereal, flour, sugar, baking powder and salt. Cut in margarine until mixture resembles coarse crumbs.
3. Stir in milk and egg until well combined. Fold in peaches. Spread batter evenly in greased 9 x 9 x 2-inch pan. Sprinkle with topping.
4. Bake at 400°F about 25 minutes or until golden brown. Serve warm or cool.
