Ingredients
 
 

For the Mug Cake:

  • 25 grams almond flour
  • 15 grams powdered erythritol
  • 15 grams butter melted
  • 15 grams full-fat Greek yogurt
  • 1 egg
  • ½ teaspoon vanilla extract
  • ½ teaspoon baking powder
  • ½ teaspoon lemon zest
  • 1 teaspoon lemon juice
  • A few fresh thyme leaves

For the Cream Cheese Glaze:

  • 15 grams cream cheese softened
  • 15 grams heavy whipping cream
  • 5 grams powdered erythritol
  • teaspoon vanilla extract
  • teaspoon lemon zest

Instructions
 

Make the Mug Cake:

  • In a mixing bowl, whisk together the almond flour, erythritol, butter, yogurt, egg, vanilla extract, baking powder, lemon zest, lemon juice, and thyme leaves until smooth and well combined.
  • Pour the batter into a microwave-safe mug or ramekin.

Cook the Cake:

  • Alternatively, bake in a preheated oven at 175°C (350°F) for 15–20 minutes until the cake is set. Avoid using a mug in the oven; use a ramekin or oven-safe dish.
  • Let the cake cool to room temperature before glazing.

Make the Glaze:

  • In a small bowl, whisk together the softened cream cheese, heavy cream, erythritol, vanilla extract, and lemon zest until smooth.

Glaze and Serve:
