Preheat oven to 350 degrees. Grease 8 inch square baking pan. Set aside. In a small saucepan over low heat, melt butter and carob powder, stirring until thoroughly mixed; remove from heat and cool slightly. In a small bowl, beat together honey and eggs; slowly add carob mixture, beating until blended. Stir in vanilla, to taste.

In a medium bowl, sift oat flour, baking powder and salt; add walnuts ( or other nuts). using a spatula, stir in carob mixture and mix. Pour mixture into prepared pan and bake for 25 minutes. When done, the center will still be somewhat soft, but the edges will be cake-like. Cool 10-15 minutes before cutting into squares. If squares are too soft to cut, refrigerate pan 15 minutes or longer, until Carob Brownies are firm enough to cut.

NOTES:
Carob powder can be found at health food and specialty stores.

To make your own oat flour, pulse one cup uncooked oatmeal in a blender container or bowl of a food processor until finely ground; about 30 seconds.
