Print Recipe


  • 3 tablespoons Lotus Biscoff spread warmed
  • 4 tablespoons plain flour
  • 0.5 teaspoon baking powder
  • 4 tablespoons milk
  • 1 tablespoon vegetable oil


  • 1-2 scoops vanilla ice cream
  • 1 tablespoon Lotus Biscoff spread warmed
  • 1 Biscoff Creme


  • Add the Biscoff spread into the mug and microwave for 30 seconds to loosen. Next, add the flour, baking powder, milk and vegetable oil. Use a fork to mix the ingredients together until a batter has formed and white streaks of flour are no longer visible.
  • Microwave for 1 min and 30 seconds (see notes)
  • Remove from the microwave and top with a couple of scoops of vanilla ice cream and a bit more warm Biscoff spread.
  • Eat immediately. Enjoy!



  • Don't forget to warm your Biscoff spread, otherwise the batter will be difficult to mix and will result in you over mixing. 
  • I used semi-skimmed cow's milk but whole milk or any dairy-free alternative will also work perfectly. 
  • Use any flavourless oil such as vegetable, canola or groundnut oil. 
  • If your cake batter feels very thick add another splash of milk to loosen it. 
  • Microwave timings will vary depending on the wattage of your microwave. Check for doneness after 1 minute. When it's ready the mug cake will be dry and springy to the touch. 
  • Best served immediately.
