Ingredients

Dry Ingredients

  • 40 grams plain flour or all purpose flour, sifted
  • 30 grams (2 tablespoons) brown sugar
  • 1/4 teaspoon baking powder
  • Pinch of salt

Wet Ingredients

  • 30 grams (2 tablespoons) unsalted butter, melted
  • 1/2 teaspoon vanilla flavoring
  • 45 ml (3 tablespoons) full fat or whole fat milk
  • 1 egg yolk

Other

  • 30 grams (2 tablespoons) Biscoff cookie spread, divided

Instructions

  1. Mix Dry Ingredients: In a large mug, combine the sifted flour, brown sugar, baking powder, and a pinch of salt. Stir or whisk the dry ingredients thoroughly to ensure they are evenly mixed.
  2. Add Wet Ingredients: Pour in the melted unsalted butter, vanilla flavoring, full-fat milk, and egg yolk to the mug. Stir briefly but thoroughly just until all ingredients are combined to form a smooth batter.
  3. Add Biscoff Spread to Batter: Stir in 1 tablespoon of the Biscoff cookie spread into the cake batter, gently folding it through to integrate the signature flavor into the mixture.
  4. Microwave the Cake: Microwave the mug batter on high (1,000 watt microwave) for approximately 80 seconds. Cooking times may vary depending on your microwave, so watch for when the cake springs back lightly to the touch, indicating it is done. Let the cake cool for one minute after microwaving.
  5. Finish and Serve: Top the warmed cake with the remaining tablespoon of Biscoff cookie spread. Serve immediately, optionally with a scoop of ice cream or a dollop of cream to elevate the dessert experience.

Notes

  • Measurements: For accuracy, it’s best to use a baking scale. This recipe uses UK/US standard tablespoon sizes (1 tablespoon = 15 ml).
  • Cooking Time: Microwave wattage varies, so consider the 80 seconds as a guideline. When the cake feels dry or rubbery, it is overcooked; reduce time next attempt by 10-15 seconds accordingly.
  • Storage: This mug cake is best enjoyed immediately, as it does not keep well or maintain its texture once cooled and stored.
  • Serving Suggestion: Enhance your mug cake by adding a scoop of ice cream or a dollop of cream on top for extra indulgence.
