Microwave Chocolate Snack Cake - cooking recipe

Ingredients

FOR CAKE
1 1/2 cups all-purpose flour
1 cup granulated sugar
3 tablespoons unsweetened cocoa powder (I use Ghirardelli brand)
1 teaspoon baking soda
1/4 teaspoon salt
1 cup cold water
1/3 cup canola oil
1 tablespoon white vinegar or 1 tablespoon apple cider vinegar
1 teaspoon vanilla extract
FOR SAUCE
1 cup granulated sugar
3 tablespoons cornstarch
2 tablespoons unsweetened cocoa powder
1 cup boiling water
1 tablespoon unsalted butter
1 teaspoon vanilla extract
salt, to taste (optional)

Preparation

Combine flour, sugar, cocoa powder, salt.
Stir in oil, cold water, vinegar, and vanilla until blended well.
Pour into an UNgreased 8\" microwave safe square baking pan.
Microwave on HIGH for about 6-8 minutes, turning the dish every 2 minutes, or until a toothpick tests clean when inserted near the center.
FOR Sauce:In a 1 quart microwave safe bowl, combine sugar, cornstarch, and cocoa powder until combined well.
Stir in water and a dash of salt (if using).
Microwave on HIGH for 2-3 minutes, stirring occasionally, or until the mixture comes to a boil.
Once it hit the boiling point, cook another 1 minute more.
Stir in butter and vanilla and mix well.
Slice cake into squares and serve the warm sauce over the still warm cake.
I like to add some sprinkles, shredded coconut,or chopped nuts on top too.
