Healthy chocolate cake

I tried this recipe for my friends going away party from http://healthyindulgences.net/ and we loved it! I now am adopting it!!

The best part about this cake is that it’s totally budget-friendly. It’s basically beans, eggs, and cocoa.
 
Healthy Flourless Chocolate Cake

Makes a 9″ one layer cake
Ingredients:
1-15 ounce can of unseasoned black beans
OR 1 1/2 cup cooked beans, any color
5 large eggs
1 tablespoon pure vanilla extract
1/2 teaspoon sea salt
6 tablespoons unsalted organic butter OR coconut oil
3/4 cup erythritol + 1/2 teaspoon pure stevia extract
OR 1/2 cup + 2 Tablespoons honey + 1/2 teaspoon pure stevia extract

6 tablespoons unsweetened cocoa powder
1 teaspoon aluminum-free baking powder
1/2 teaspoon baking soda
1 tablespoon water (omit if using honey)

Mint Chocolate variation:
2 teaspoons mint extract (in place of 2 teaspoons vanilla)

Preparation:
Preheat oven to 325 degrees Fahrenheit. Spray a 9″ cake pan with extra virgin olive oil cooking spray, or just grease it with a thin layer of butter. Dust cocoa all over the inside of the pan, tapping to evenly distribute. Cut a round of parchment paper and line the bottom of the pan, then spray the parchment lightly.
Drain and rinse beans in a strainer or colander. Shake off excess water. Place beans, 3 of the eggs, vanilla, stevia (if using) and salt into blender. Blend on high until beans are completely liquefied. No lumps! Whisk together cocoa powder, baking soda, and baking powder. Beat butter with sweetener (erythritol or honey) until light and fluffy. Add remaining two eggs, beating for a minute after each addition. Pour bean batter into egg mixture and mix. Finally, stir in cocoa powder and water (if using), and beat the batter on high for one minute, until smooth. Scrape batter into pan and smooth the top. Grip pan firmly by the edges and rap it on the counter a few times to pop any air bubbles.
Bake for 40-45 minutes. Cake is done with the top is rounded and firm to the touch. After 10 minutes, turn out cake from pan, and flip over again on to a cooling rack. Let cool until cake reaches room temperature, then cover in plastic wrap or with cake dome (I use an overturned plastic chip bowl). For BEST flavor, let cake sit over night. I promise this cake will not have a hint of beaniness after letting it sit for eight hours! If you are stacking this cake, level the top with a long serrated knife, shaving off layers until it is flat and even. Frost immediately before serving


Healthy Chocolate Buttercream Frosting

Makes enough to thickly cover one layer, or fill and frost a halved stacked layer
Ingredients:
1/2 cup (1 stick) unsalted organic butter, softened, OR 7 tablespoons nonhydrogenated shortening
1/4 cup plus 1 tablespoon erythritol, powdered, OR 1/4 cup xylitol, powdered- (for this i used icing sugar)
5-6 tablespoons unsweetened cocoa powder
2 tablespoons half and half OR coconut milk
1 teaspoon pure vanilla extract
Pinch of sea salt
Good-tasting pure stevia extract, to taste
Optional addition for a glossy finish:
1 fresh organic egg yolk

Preparation:
Cream the butter in a small bowl until fluffy. Powder erythritol or xylitol in a coffee grinder or Magic Bullet for a minute or two, until extremely fine in texture (reminiscent of powdered sugar). Let sweetener settle in grinder before opening the top. Stir powdered sweetener into butter with a spatula, then beat until smooth. Slowly blend in the cocoa powder (unless you want to redecorate your kitchen), vanilla, and sea salt. Beat in the half and half and egg yolk, if using. Add stevia, starting with 1/16 teaspoon. You’ll probably use less than 1/4 teaspoon. Just keep tasting and adjust sweetness to your liking.
