Ingredients
- 4 tbsp all-purpose flour
- 3 tbsp granulated sugar
- 1/4 tsp baking powder
- 3 tbsp milk
- 2 tbsp vegetable oil
- 1 tbsp lemon juice
- 1 tsp lemon zest
- 1 egg white
- 1/8 tsp cream of tartar
- 1 tbsp powdered sugar
Instructions
- Step 1: In a microwave-safe mug, whisk together 4 tbsp all-purpose flour, 3 tbsp granulated sugar, and 1/4 tsp baking powder. Stir in 3 tbsp milk, 2 tbsp vegetable oil, 1 tbsp lemon juice, and 1 tsp lemon zest until smooth and lump-free.
- Step 2: Microwave the mug cake batter on high for 90 seconds, or until the cake has risen and is set in the middle. Remove carefully; the mug will be hot.
- Step 3: In a clean bowl, beat 1 egg white with 1/8 tsp cream of tartar using an electric mixer until soft peaks form. Gradually add 1 tbsp powdered sugar and continue beating until stiff, glossy peaks develop.
- Step 4: Spread the meringue evenly over the hot cake in the mug. Return to the microwave and cook on medium power for 20-25 seconds until the meringue is puffed and slightly browned. Let cool for 2 minutes before enjoying.
