I found this recipe in good housekeeping website (http://www.goodhousekeeping.com/recipefinder/healthy-makeover-brownies-recipe?click=recipe_sr)

I took this recipe and modified a little bit.  I don’t like strong cocoa taste or too much sugar.  So I reduced the amount of sugar a little bit and replaced ¼ cup of cocoa powder with all-purpose flour.  The brownies came out quite good.  But I had to keep them in an air tight container.  When I left them outside for a while, they became a little dry.

Here is how the brownie looks when cut:

Ingredients

• 1 teaspoon instant coffee granules
• 2 teaspoons vanilla extract
• ¾ cup all-purpose flour
• ¼ cup unsweetened cocoa powder
• ¼ teaspoon baking powder
• 1/8 teaspoon salt
• ¾ cup sugar
• ¼ cup vegetable oil spread or cooking oil
• 3 large egg whites
• About 10 walnuts chopped (optional)
• Butter of greasing baking pan

Method

• Preheat oven to 350F.
• Butter a square (8 x 8 inch) baking pan
• Add vanilla extract to coffee powder/granules and let it dissolve
• Sift flour and combine cocoa powder, flour, salt, and baking powder
• In a medium bowl whisk together oil, egg whites, sugar and coffee mixture until well mixed and smooth
• Blend in flour mixture and walnuts and mix well
• Spread in the prepared pan and bake for about 25 – 30 minutes or until toothpick inserted comes out clean

• Cool pan for about 2 hours
• When cool cut brownies into squares
• Sprinkle with powdered sugar

• Makes about 16 brownies
