I know a lot of people doing Keto do some version of Bullet Proof Coffee (BPC). The first time I attempted it, I poured my piping hot, just brewed coffee with all the ingredients into our blender only to realize it was not sealed tight at the bottom. Coffee went everywhere… the counter, the floor. Baby was screaming, I was late leaving for work. It was the first and almost the last time I did BPC. Do yourselves a favor and invest in an immersion blender if you haven’t already. I brew my coffee straight to my RTIC tumbler (30oz) and then blend for 10 seconds or so. Does such a good job!
