Sorry I was trying to fix the recipe and posted it by mistake.  I have searched the web for all kinds of diabetic brownies. This one looked good.

 Low Carb Double Chocolate Walnut Brownies
Low Carb Double Chocolate Walnut Brownies1 1/2 tablespoons wheat bran, or oat bran 
1 1/4 cups plus 1/2 tablespoon soy flour 
4 ounces unsweetened baking chocolate 
1/2 cup unsalted butter 
2 cups sugar substitute (recommended: Splenda) 
1/2 cup heavy cream 
5 large eggs 
1 tablespoon no sugar added vanilla extract 
2 teaspoons baking powder 
1/2 cup chopped walnuts 
Low Carb Chocolate Frosting, recipe follows 
Special Equipment: 8-inch square baking pan 
Preheat oven to 325 degrees F. 
Spray pan with nonstick vegetable oil cooking spray. Set aside. 
Mix wheat bran and 1/2 tablespoon soy flour together and sprinkle evenly over the inside of the greased pan, also coating the sides. Place the unsweetened chocolate and butter in a steel bowl and melt over a saucepan of simmering water. Whisk in 1 cup sugar substitute and 1/4 cup heavy cream. Once thoroughly blended, turn off heat and keep warm until needed. 
With an electric mixer on high, beat the eggs, 1 cup sugar substitute and the vanilla extract just until blended. Reduce to low speed and then blend in the chocolate mixture. With a wooden spoon, mix in the baking powder, 1 1/4 cups soy flour, walnuts, and 1/4 cup heavy cream. 
Spread evenly into the prepared pan and bake on the center rack for 35 to 40 minutes, or until a toothpick inserted in the center comes out clean. (Do not over-bake or brownies will be dry and hard.) 
Cool completely before frosting with low carb chocolate frosting. 
Cut into 5 rows by 5 rows to make 25 pieces.
