01 / WHAT YOU NEED

Ingredients

½ cup all-purpose flour 1 teaspoon baking powder ½ teaspoon baking soda 1 pinch salt ½ teaspoon olive oil 1 small egg ¼ cup lemon juice 1 tablespoon lemon zest butter for greasing

02 / HOW TO MAKE IT

Let's cook.

Step 1

Start by mixing the flour, baking powder, baking soda, and salt together in a small bowl. In another bowl, whisk the milk, brown sugar, olive oil, egg, lemon juice, and lemon zest until everything is well combined. Pour the wet ingredients into the dry and stir just until the batter comes together—you can leave a few lumps. Grease a large microwave-safe mug with a bit of butter, then pour in the batter. Pop the mug in the microwave and cook it for about 3 minutes. Once it’s done, let it sit for a few minutes to finish setting before digging in.

Cook's tip

- Use fresh lemon juice and zest for the best flavor.
- Do not overcook; microwave in short bursts and check frequently to avoid dryness.
- Stir the batter well to ensure even mixing and a smooth texture.

Serving ideas

Enjoy it warm right out of the mug, perhaps topped with a dollop of whipped cream or a sprinkle of powdered sugar. It also pairs nicely with a scoop of vanilla ice cream for an extra indulgent treat.

Storage & leftovers

This cake is best eaten immediately but can be stored in an airtight container in the refrigerator for up to one day. Reheat gently in the microwave before serving to restore its soft texture.
