My wife and I have adapted a low carb high fat lifestyle and enjoy our coffee every morning. Maryann(my wife) found a simple way to make a coffee which tastes like a frappe or cappuccino.
We use a Magic Bullet to blend it. This "as seen on TV" works really well.
It is a 1/2 tbs butter and 1 tbs coconut oil blended with a cup of coffee. We are addicted! This stuff is great! I want to try it with espresso or super strong coffee(tar).
