Description

This Moist Lemon Mug Cake is a quick and easy single-serving dessert bursting with fresh lemon flavor. Perfectly soft and tender, it can be whipped up in just 5 minutes using a microwave, making it an ideal treat for a spontaneous sweet craving. Enhanced with fresh lemon juice and zest, this cake is rich yet light, thanks to the addition of an egg yolk and butter. Serve it as is or with your favorite ice cream or lemon curd for an extra indulgent touch.


Ingredients

Dry Ingredients

  • 1/4 cup all-purpose flour
  • 2 tbsp granulated sugar
  • 1/4 tsp baking powder
  • Pinch of salt

Wet Ingredients

  • 1 tbsp butter, melted
  • 2 tbsp milk (whole milk or 2%)
  • 1/2 tbsp fresh lemon juice
  • 1/2 tsp lemon zest
  • 1/4 tsp vanilla extract
  • 1 egg yolk


Instructions

  1. Combine Dry Ingredients: In a microwave-safe mug, thoroughly whisk together the all-purpose flour, granulated sugar, baking powder, and a pinch of salt to ensure even distribution and aeration of the baking powder.
  2. Mix Wet Ingredients: Add the melted butter, milk, fresh lemon juice, lemon zest, vanilla extract, and egg yolk into the mug with the dry ingredients. Stir until the batter is smooth and well combined, avoiding lumps.
  3. Microwave Cooking: Microwave the mug cake for 50-60 seconds. Start at 50 seconds, then continue in 10-second increments if necessary, until the top is set but still slightly glossy to maintain moisture.
  4. Cool and Serve: Allow the cake to cool for one minute inside the mug before eating. For serving, consider adding a scoop of ice cream, a dollop of lemon curd, or a light dusting of powdered sugar to enhance the flavor.

Notes

  • Be careful not to overcook the mug cake to avoid dryness; microwave times may vary based on wattage.
  • Use fresh lemon juice and zest for the best, brightest lemon flavor.
  • This recipe works well with both whole milk and 2% milk.
  • You can substitute butter with a neutral oil for a dairy-free option, but the flavor and texture may be slightly different.
  • For a sweeter variation, add a sprinkle of powdered sugar on top after cooking.
  • Ensure the mug is microwave-safe to prevent accidents.
