Keto Vanilla Mug Cake

This keto mug cake is one of my favourite easy treats. It is like a single serve vanilla pound cake. Perfect for a spontaneous sugar free dessert straight out of the mug - or turn it out onto a plate!

Notes

  • 5g net carbs per serving. Makes 1 serving. 
  • My microwave operates at 900W and my cake took 80 seconds to cook. Here's a quick overview of recommended baking times for this cake recipe: 
  • After these times, check whether the cake is done. If it's still undercooked, add increments of 10 seconds. 
  • Choose a cup or ramekin that holds a minimum of 200ml. Otherwise the dough will overflow as it rises. 
  • 600W = low power. 100 seconds. 
  • 800W = 90 seconds.
  • 900W = 80 seconds. 
  • 1000W = 70 seconds.
