Garbanzo Bean Chocolate Cake

I was lucky enough to have an awesome neighbor who used to surprise me with yummy gluten free treats...this was BY FAR the BEST cake I have tried since being diagnosed with Celiac's Disease! It's so good...even non-celiac's gobble this one up!

Garbanzo Bean Chocolate Cake (Gluten Free!)

"A very good high protein alternative to flourless chocolate cake. Give it a try!"

Ingredients:
1 1/2 cups semisweet chocolate chips
1 (19 ounce) can garbanzo beans, rinsed
and drained
4 eggs
3/4 cup white sugar
1/2 teaspoon baking powder
1 tablespoon confectioners' sugar for dusting

Directions:
1. Preheat the oven to 350 degrees F (175 degrees C). Grease and flour a 9 inch round cake pan.
2. Place the chocolate chips into a microwave-safe bowl. Cook in the microwave for about 2 minutes, stirring every 20 seconds after the first minute, until chocolate is melted and smooth. If you have a powerful microwave, reduce the power to 50 percent.
3. Combine the beans and eggs in the bowl of a food processor. Process until smooth. Add the sugar and the baking powder, and pulse to blend. Pour in the melted chocolate and blend until smooth, scraping down the corners to make sure chocolate is completely mixed. Transfer the batter to the prepared cake pan.
4. Bake for 40 minutes in the preheated oven, or until a knife inserted into the center of the cake comes out clean. Cool in the pan on a wire rack for 10 to 15 minutes before inverting onto a serving plate. Dust with confectioners' sugar just before serving.

Suggestion by myceliacs.blogspot.com: ****HINT**** If you have a VitaMix I suggest putting all the ingredients in the mixer, mix until smooth and spoon into the greased pan. You don't have to melt the chocolate first...the speed of the mixer chops them up so fine you don't have to worry about it!!! It works great!
