You'll find a lot of heavy whipping cream fans here.  I make mine like you do yours sometimes, but with 16 oz. coffee (mostly decaf).  However, I find that this is ~highly~ stimulating for me.  GREAT if I am alone and want to buzz around and get a TON of stuff done...  Not so great if I am doing schoolwork with the kids and actually need to chill out a bit.  😀But I think it is the MCT oil that does this ^ to me.Lately, if I am not hungry or don't have time to cook breakfast right away -- I just eat a tablespoon of unsalted, grass-fed butter with my coffee.  I prefer it black, but I need the fat with it.  I also add my (tasteless) collagen protein powder almost every morning.

Just coffee and HWC here. I HAVE tried coffee/butter before but never with to the BP coffee route.

I still do butter/MCT in my coffee in the morning. I used to do butter/egg yolks. As long as you’re not limiting your fat other places because of it, I don’t see an issue with either method or HWC.
