Vegetable Brownies?!!

Brownies (With spinach and carrot)
From “Deceptively Delicious,” Jessica Seinfeld,
with my adaptations added in parentheses

3 oz semisweet chocolate
½ cup carrot puree
½ cup spinach puree
½ firmly packed brown sugar
¼ cup cocoa powder, unsweetened
2 tablespoons soft tub margarine spread(I use non-dairy*)
2 teaspoons pure vanilla extract
2 large egg whites(I used egg replacer-can try other substitutes as well)
¾ cup oat flour(blend old fashioned oats in a blender)
½ teaspoon baking powder
½ teaspoon salt

Melt chocolate. Combine melted chocolate, vegetable purees, sugar, cocoa powder, margarine, and vanilla. Whisk 1-2 min until creamy.
Beat egg whites(or egg replacer), then stir in flour, baking powder, and salt. Baker 35-40 min in greased 8 x 8 pan. Cool completely before eating; the spinach flavor disappears when brownie is cool. Absolutely delicious and really healthy for a brownie!

*Smart Balance is the tub spread I currently use, but check labels carefully, most recently only one type of Smart Balance has no casein and no whey.
