Food and recipes

I saw a video about the heart attack grill does anybody know how to make a butterfat shake?

Not sure if it is the same, but I put 100g of butter into a big cup, fill it up with milk and add 1/2-1 teaspoons sugar and put for 1-2mins into Microwave. That stuff is the pure waist blaster.

Someone in 2012 decided a copycat (with no sources keep in mind) that put it with the maximum butterfat content for churning at an ice cream level and not into butter, here it is fatgirlkitchen.typepad.com/fatgirl/2012/06/homemade-heart-attack-grill-style-butterfat-milkshakes.html
