Vegan Brownies

I used to make killer vegan brownies all the time, but I haven't made them in years. My daughter needs to contribute to her Daisy crossover today, so I volunteered to make brownies to protect her dairy-free status.

The original Betty Crocker recipe:
Melt
2/3 cup butter
5 ounces unsweetened chocolate

Mix separately
1 3/4 cups sugar
2 teaspoons vanilla
3 eggs

Add chocolate
One cup flour

Mix and bake in greased pan for 40-45 minutes at 350 until brownies pull from side of pan
My version

2/3 cup margarine
3 ounces semisweet chocolate
1 ounce dark chocolate (in candy bar form because I ran out of the other)
3 tablespoons cocoa powder
1 tablespoon canola oil

For pre-batter:
3/4 cup sugar
3/4 cup applesauce
2 teaspoons vanilla

And the flour as directed
