Question: I am making chocolate brownies without sugar using the following ingredients:

* cocoa nibs, 1 & 1/4 cups
* carob powder, 1/4 cup
* margarine, 125 g
* flour, 50 g
* stevia, 1 tablespoon
* vanilla essence, 2 teaspoon
* baking powder, 1/2 teaspoon
* 2 eggs

How can I make the brownie less dry and have more flavor? I don't want to add sugar as it aggravates my skin.

Answer: 
That 1/4th cup margarine and the 2 eggs are not enough to give those brownies the moisture they need. 

I suspect you want something low in sugar and fat. Evelyn Tribole, MS, RD created two books that talk about substitutions for fat and sugar in recipes. One technique to replace fat (like butter) in a recipe is to use *baby food prunes or applesauce*.

Does it work? I made her brownies that substituted baby food prunes for traditional butter. The brownies were super moist and I couldn't taste anything "prunes". This recipe is in her first [Healthy Homestyle Cooking](http://rads.stackoverflow.com/amzn/click/0875963617) cookbook.

**For right now, substitute cup for cup baby food prunes or applesauce for the butter/margarine.** I suggest half margarine and half the chosen substitute. That way you get the flavor of margarine but without the fat.

**Or, if you don't mind the fat just add more margarine.** The average brownie recipe usually calls for nearly a full stick (or more) of butter or margarine. It's the margarine that adds moisture to brownie crumb. Or oil, or any kind of fat you prefer.
First, I agree with Tarak'ha's suggestions because it looks like you're trying to keep things somewhat healthy.

Since it looks like you're trying to make healthier brownies, I just wanted to mention yet another less heard of healthy fat replacement in baking: *Finely shredded / pureed beetroot*. I learned this trick from a show called "Cook Yourself Thin" for their [chocolate cake](http://www.food.com/recipe/beetroot-chocolate-fudge-cake-from-cook-yourself-thin-255558). In the show they talk about how the moisture from the beetroot replaces most of the moisture and fat that is usually added by vegetable oil. It's just another alternative to consider.

Here is a brownie recipe that uses *beets & coconut oil* for the "fat" component. It uses coconut sugar, but you can substitute for your stevia if you'd like.
