Ingredients

Cake Ingredients

  • 1 1/2 tablespoons pure maple syrup
  • 1 tablespoon coconut oil (melted)
  • 2 tablespoons lemon juice (from about 1 lemon)
  • 1 tablespoon almond milk
  • 2 teaspoons lemon zest
  • 4 1/2 tablespoons all purpose flour
  • 1/2 teaspoon baking soda

Glaze Ingredients

  • 2 tablespoons powdered sugar
  • Lemon juice (for thinning glaze as needed)

Instructions

  1. Prepare the syrup and oil mixture: In a large microwave-safe mug, stir together the pure maple syrup and melted coconut oil until fully combined.
  2. Add lemon elements: Stir in the lemon juice, almond milk, and lemon zest. The mixture may slightly separate; if it looks chunky or curdled, microwave for a few seconds until the coconut oil melts again, restoring a smooth consistency.
  3. Incorporate dry ingredients: Quickly add the all purpose flour and baking soda to the mug and stir just until combined. Avoid overmixing to keep the cake light.
  4. Microwave the cake: Cook the mug cake in the microwave for about 70 seconds or until the top surface is no longer wet and the cake springs back when touched gently. Let it cool for a few minutes before serving or glazing.
  5. Make the lemon glaze: In a small bowl, add lemon juice drop by drop to the powdered sugar, mixing until you reach a thin, drizzle-able consistency perfect for pouring.
  6. Glaze and serve: Drizzle the lemon glaze over the mug cake or pour it all on top, then enjoy your fresh, vibrant lemon dessert.

Notes

  • Use freshly squeezed lemon juice and zest for the best bright lemon flavor.
  • Microwave wattages vary, so adjust cooking time slightly if needed: less if your microwave is powerful, more if not fully cooked.
  • Let the mug cake cool slightly after microwaving to set the texture before adding glaze.
  • For a dairy-free option, almond milk and coconut oil are already suitable.
  • Do not overmix the batter to avoid a dense cake.
