chocolate cake recipe (and it's healthy!)

I tried a new recipe last night and it was a complete HIT with my family - healthy chocolate cake with a secret.

Looks delicious, right? Yeah, the cake was moist and the frosting perfectly creamy. So what's the secret? Ready for this.....? Black beans. That's right. No flour in the cake whatsoever, instead, there are beans. Crazy right? But it works!

The next thing I want to try is avocado chocolate mousse! I'll let you know how it goes ;)
