  • Melt butter in the mug you will be using.
  • Place cream cheese in a bowl and microwave in 10-second intervals. do NOT over melt it.
  • Swirl the butter in the mug to coat the edges then add butter to the cream cheese bowl.
  • Beat your egg in a 2nd bowl.
  • Add collagen and baking powder to your egg and beat/mix together.
  • Add a little bit of the butter and cream cheese mix to your egg mixture. Once mixed in, combine the rest. We are only adding a little bit to not overheat the egg if the cream cheese mixture is too hot.
  • Once everything is combined, pour your batter into your mug.
  • Cook for 1 minute and 5 seconds. Less time if you want it gooier.
