Ingredients

Scale
  • 4 tbsp (about 30 g) all-purpose flour
  • 2 tbsp (25 g) sugar
  • 1/4 tsp baking powder
  • A pinch of salt
  • 3 tbsp (45 ml) milk (any kind, whole milk recommended)
  • 2 tbsp (30 ml) vegetable oil (can substitute melted butter)
  • 1 tsp fresh lemon zest
  • 1 tbsp (15 ml) freshly squeezed lemon juice
  • 3 tbsp (about 30 g) fresh or thawed blueberries
  • 1/4 tsp vanilla extract (optional)

Instructions

  1. Mix dry ingredients: In your mug or bowl, combine 4 tbsp (30 g) all-purpose flour, 2 tbsp (25 g) sugar, 1/4 tsp baking powder, and a pinch of salt. Stir until evenly mixed.
  2. Add wet ingredients: Pour in 3 tbsp (45 ml) milk, 2 tbsp (30 ml) vegetable oil, 1 tsp fresh lemon zest, 1 tbsp (15 ml) lemon juice, and 1/4 tsp vanilla extract if using. Mix well with a fork until smooth and slightly thick without lumps.
  3. Fold in blueberries: Gently stir 3 tbsp (30 g) fresh or thawed blueberries into the batter, keeping them intact.
  4. Microwave: Cook the mug in the microwave on high for 90 seconds to 2 minutes (about 1000 watts). The cake should rise and spring back when touched. If wet on top, add 10-second intervals until set, avoiding overcooking.
  5. Cool and enjoy: Let the mug cake rest for a minute to cool slightly before eating.

Notes

Use fresh lemon zest for best flavor. Adjust microwave time based on your microwave’s wattage. Do not overmix batter to avoid rubbery texture. Let cake cool slightly before eating to enhance flavor and avoid burns. For a crispier top, briefly broil for 30 seconds watching carefully.
